Description

1. Field of the invention

The invention relates to a fireplace system for combustion plants, in particular for gas or oil-fired heating systems.

2. State of the art

Buildings are mostly heated by burning hydrocarbons such as oil, natural gas or coal. The resulting carbon dioxide is partly responsible for the greenhouse effect. The retention of carbon dioxide would require such a large amount of energy that it was no longer worthwhile from the energy balance to burn the hydrocarbons. In order to keep air pollution as low as possible and to save our resources on fossil fuels, it is important to reduce the consumption of fuel.

Since the hydrocarbons are derived from living matter, they contain a large amount of carbon and in smaller quantities a variety of other substances, such as sulfur and nitrogen.

These substances get into the combustion gas during the combustion of hydrocarbons. The combustion gas therefore contains in addition to water vapor, carbon dioxide, soot, sulfur oxides and nitrogen oxides and sulfuric acid. Most of the nitrogen oxides are nitrogen, which also comes from the combustion air.

In contrast to carbon dioxide and nitrogen oxides, water vapor, soot, sulfur oxides and sulfuric acid can be at least partially retained by suitable means but with high technical and energy expenditure.

Traditional fireplaces are either made of chamotte or made of stainless steel. These materials are not sufficiently corrosion resistant and sputtered if the combustion gas would condense therein, i. they are exposed for a long time to a liquid, acidic condensate with pH values of 1.5-3.7.

The temperatures in such conventional chimneys must therefore not fall below the dew point of the combustion gas to prevent condensation of the combustion gas. In conventional chimneys, therefore, the temperature of the combustion gas is adjusted to the boiler so that there is no condensation in the chimney and therefore no sooting.

This has the consequence that the combustion gases are completely discharged into the atmosphere, which means a high pollution of the atmosphere and a high energy loss.

For some time, therefore, chimneys made of high-quality plastics such as PVDF (polyvinylidene fluoride) are used, which are able to withstand the action of the condensate. Here, a condensation of the combustion gases is deliberately allowed and thereby recovered a large part of the energy which is bound in the combustion gas. One speaks therefore also of so-called condensation chimneys. In addition, a large part of the pollutants contained in the flue gas, polluting substances such as sulfuric acid, unburned hydrocarbons, water vapor and soot can be retained in the chimney pipe.

The energy savings that come from a lower demand for fuel, this technique is based on several factors. First of all, the condensation temperature of the boiler can be reduced to a minimum become. In the so-called condensing technology, the temperature of the exhaust gas when leaving the boiler only about 30-40 ° C and in the low-temperature technology about 90-140 ° C amount. A reduction of the flue gas temperature means a more efficient use of the heat of combustion for heating the heat carrier (usually water) and a saving of expensive fuel. Condensation chimneys allow for the first time to operate the boiler with the minimum boiler water temperature specified by the manufacturer, from which then the lowest possible exhaust gas temperature and from this again the highest possible efficiency of the firing plant results. In addition, this technology allows considerably longer burner run times, whereby startup and shutdown losses (eg factor 10) of the system are avoided and material stress is minimized.

In addition, a further cooling of the flue gas takes place in the condensation chimney, which is not thermally insulated in this technique and is surrounded by incoming fresh combustion air. The preheated along the chimney pipe of the condensation chimney along fresh and ambient temperature-cold combustion air is preheated. As a result of the cooling of the combustion gases, a large part of them will condense, the heat of condensation in turn being given off to the fresh combustion air.

The thus preheated fresh combustion air is then used to operate the boiler and thus reused the heat of the combustion gases.

When the combustion gases are condensed in the chimney, a liquid, strongly acidic condensate flows down the chimney walls. At the foot of the chimney pipe, the condensate is caught and sent to a neutralization tank, which binds and neutralizes the pollutants. This neutralization tank usually contains an activated carbon filter and a neutralization granules, which neutralizes the acids of the condensate. The neutralization granules are either chemically produced calcium carbonate or natural lime. After neutralization, pure harmless water is released from the condensate, which is sent to the sewage system. For example, one liter of burnt oil produces 0.8 liters of condensate that is not released into the environment as exhaust gas.

The DE 3421 112 A1 describes a condensation chimney, which is used for the application of the technique of cold, wet, condensing chimney. This fireplace is most effective in terms of heat recovery and combustion gas purification in heating systems for smaller buildings. Such a fireplace system is made of individual welded together plastic pipes and is only suitable for a fireplace.

The invention therefore has the task of providing a condensation chimney system for multi-storey buildings with multi-storey heating, to recover heat energy and in particular to significantly improve the installation and investment costs of such a condensation chimney system.

3. Summary of the invention

This object is achieved by the subject matter of the independent claims. Advantageous developments of the invention are the subject of the dependent claims.

In particular, the o.g. Problem solved by a chimney pipe module, comprising a pipe section of a plastic material, a sleeve portion of a plastic material, which connects at the upper end of the chimney pipe section, a Feuerungsanschlussrohr of a plastic material, for connecting a fireplace to the chimney pipe module, wherein the chimney pipe module is configured in one piece, and has a total length at floor level.

With this configuration, in particular its length, the chimney pipe module can advantageously in multi-storey houses, especially high-rise buildings, with floor heating be used. The chimney module is approximately as long as a floor of such a building. Thus, in each case an inventive chimney pipe module per floor can be plugged together to provide an entire chimney system for floor heating. In contrast to solutions with individual components, branches, fittings, etc., which would have to be elaborately welded together or put together in the prior art, the assembly effort is reduced considerably. Furthermore, increased by the one-piece design of the chimney pipe module and the mounting safety, since the chimney pipe module can not have any assembly-related leaks. On the construction site, no adjustments must be made.

Due to the chimney pipe module according to the invention thus for the first time multi-storey buildings with decentralized heat generation by floor heating systems can be economically equipped with the energy-saving wet chimney technology.

Furthermore, the same amount of storey-high chimney pipe modules can reduce packaging costs. For example, at seven storeys seven chimney tube modules of the same length and other elements, such as a roof duct and a base module, can be shipped in a common carton in a theft-proof manner.

Preferably, the total length of the chimney pipe module is 2m-5m, more preferably 2m-4m, even more preferably 2m-3m, and even more preferably 2.3m-2.8m. Thus, only one chimney pipe module is required per floor of a building and the entire chimney system consists essentially of nested floor-high chimney pipe modules.

In a first preferred embodiment, the chimney pipe module further comprises centering tabs which are arranged at the upper end of the sleeve portion and are bent upwards and outwards. These Zentrierlaschen center when nesting the long chimney pipe modules in a conventional masonry shaft, the lower end of the next chimney pipe module in the sleeve section. Thus, the installation of the chimney pipe modules can be done virtually blind, ie without vision.

Preferably, the chimney pipe module further comprises flexible spacers which are arranged on the outside of the pipe section. These spacers center on the one hand the chimney pipe module during installation in the chimney. On the other hand, they ensure that the space required for heat recovery remains between the chimney pipe module and the chimney shaft and can be sucked into the fresh combustion air and preheated.

Preferably, the chimney pipe module further comprises at least one fastening element for fixing the chimney pipe module in a chimney stone, wherein the fastening element is arranged in the region of the upper end of the chimney pipe section. By means of the at least one fastening element, the chimney pipe module can be securely fixed in the chimney shaft without any additional fastening. Each chimney pipe module preferably has three fastening elements.

Preferably, the fastening element is rod-shaped and has a stop and an anchoring area. Through the stop and the anchoring area, the fastener can be used in a defined position in appropriate recordings of a fireplace block. Thus, the installation of the chimney pipe module can be done quickly and safely simply by placing the next fireplace block, wherein the fastener is clamped by the weight of the chimney piece. The anchoring area preferably consists of a different plastic material (eg polyamide 6) than the rest of the fastening element. Therefore, for the anchorage an optimally suitable for anchoring in the chimney stone, for example, softer plastic can be used, as for the rest of the chimney pipe module. For this purpose, preferably an acid-resistant plastic, more preferably PVDF is used.

In another preferred embodiment, the fastening element is designed as a downwardly open U-shaped profile. Thus, it can be hooked into the ribs of a chimney block without further installation effort and thus fasten the chimney pipe module in a very simple manner in the chimney.

Preferably, the chimney pipe module has three fastening elements which are aligned at right angles to one another in a plane and substantially perpendicular to the longitudinal direction of the chimney pipe section. Preferably, three fasteners are provided which secure the chimney pipe module in three sides of the chimney, which is located on the fourth side of the chimney pipe module Feuerungsanschlußrohr. The fasteners are simply clamped during installation between the flange areas of two chimneys and possibly walled or glued to the chimney blocks. If they are designed as U-shaped tabs, they are simply placed on corresponding ribs of a chimney piece.

The pipe section of the chimney pipe module preferably has at least one section of a flexible pipe. As a result, the pipe section is flexible and the chimney pipe module can be easily inserted into the chimney. In addition, the heat transfer between the hot flue gases and the cold along-flowing combustion air increased by the greatly enlarged surface of the flexible tube compared to a rigid tube. In addition, the flex tube is thinner compared to a rigid tube and it can be saved material. Due to the thinner wall thickness results at the same time a better heat transfer. Also, the use of a flexible tube and the expansion distributed to each floor solves the problem of longitudinal expansion during operation.

The above object is also achieved by a chimney system, comprising at least one above-described chimney pipe module and at least one first chimney stone with an upper flange portion, a lower Flange region and a through hole for receiving the chimney pipe module, wherein the first chimney stone at the upper or lower flange portion has a recess for receiving at least a portion of the Feuerungsanschlußrohrs.

Thus, a chimney system is provided in which chimneys, which result in an outer chimney shaft and a chimney pipe module for floor heating, which serves the flue gas duct, are optimally matched to each other. Characterized in that the first chimney stone has a recess for receiving at least a portion of the Feuerungsanschlußrohrs at the upper or lower flange portion, the chimney pipe module can be easily inserted from the top of the storey-high chimney flue chimney stacks. The first chimney stone is the uppermost chimney stone and already provides a recess for the Feuerungsanschlußrohr. This eliminates manual adjustment work on the chimney and the chimney module completely. The installation is easy and fast by high walls of the chimney stones and per floor once insertion of the respective chimney pipe module in the chimney. For example, the chimney pipe module of the ground floor is inserted from the 1st floor and the chimney pipe module of the 1st floor from the 2nd floor.

Preferably, the chimney system further comprises at least a second chimney brick, with an upper flange portion, a lower flange portion and a through hole for receiving the chimney pipe module, wherein the upper or lower flange portion for performing the Feuerungsanschlußrohrs a corresponding to the corresponding lower or upper flange portion of the first chimney piece shape having. The first and second chimney blocks are adapted to each other so that the Feuerungsanschlußrohr between the flange is passed.

Preferably, the recess in the first chimney stone and / or a recess in the second chimney stone on a circular section-shaped, in particular a semicircular section-shaped cross-section.

The upper or lower flange region of the first and / or second chimney block preferably also has at least one recess for fastening the at least one fastening element between two chimney stacks. In this recess, the fastener of the chimney pipe module is inserted and jammed between two chimney blocks. This results in a well-defined mounting position of the chimney pipe module.

The present invention further relates to a chimney with a through-hole for receiving a chimney pipe module, in particular a chimney pipe module described above, wherein the through-opening has three longitudinal ribs which center and fasten the chimney pipe module in the through hole. As a result, further fasteners or spacers that center the chimney pipe module in the chimney shaft can be saved. The chimney pipe module is centered solely by the longitudinal ribs of the chimney. The installation of the chimney pipe module in such a special chimney stone is carried out by the chimney pipe module is inserted into the shaft with the longitudinal ribs and the fastening elements of the chimney pipe module are supported on the upper sides of the longitudinal ribs.

Preferably, the passage opening for the chimney pipe module has a substantially rectangular or square cross-section and at three of the four inner surfaces of the passage opening, a longitudinal rib is arranged in each case. Thus, the chimney pipe module is centered on each of three of four sides by each chimney stone, on the remaining side - without longitudinal rib - the Feuerungsanschlußrohr can run through the chimney stone.

The present invention further relates to a chimney system with at least one above-described chimney pipe module and a chimney, which is constructed of at least two chimney stones described above, wherein two consecutive chimney blocks are installed twisted to each other, so that the chimney pipe module is centered in the chimney of all four sides. This can be centered on all four sides with the same chimney stone with only three longitudinal ribs only by clever twisted installation of chimney blocks the chimney pipe module. In the chimney shaft longitudinal ribs are then arranged on all four sides, which support the chimney pipe module and center.

Preference is sucked through the passage opening in the area between chimney stone and chimney pipe module and / or in the area between the recess and the Feuerungsanschlußrohr fresh air for the operation of a furnace and thereby preheated by the flue gases. In such a chimney pipe system, the fresh combustion air is preheated by the hot combustion gases, recovering much of the heat of the combustion gases.

Preferably, the chimney stone is designed as a double chimney stone and additionally has a second passage opening for air for ventilation of the living space. This can be supported with the help of a chimney piece, both the actual chimney function and a controlled and energy-saving Wohnraumbe- or ventilation.

The present invention also relates to a base part for a chimney pipe, wherein the chimney pipe has a sleeve portion made of a plastic material for receiving a chimney pipe, in particular a chimney pipe module according to one of the previous embodiments, and fastening elements made of a plastic material for fastening the base part to a chimney stone and a flange Closure with condensate drain from a plastic material, wherein the base part is designed so that it can extend through the basement ceiling in the basement, the sleeve section above the basement ceiling and The flange closure with condensate drain can be arranged below the basement ceiling. Thus, the conventionally provided chimney shaft can be saved from the basement floor to the basement ceiling. The remaining chimney shaft sits on top of the basement ceiling. Thus, it is possible with the base part to direct exhaust gases through the basement ceiling into the first chimney pipe module. At the same time accumulating condensate can be led into the cellar, where it is neutralized centrally. The flange closure is used as a revision opening.

The present invention also relates to a bird protection for a chimney pipe, wherein the bird protection has a tubular connecting portion of an acid-resistant plastic material, for connecting the bird protection with a chimney pipe, in particular with a chimney pipe module according to one of the previous embodiments, as well as rod-shaped cover elements made of an acid-resistant plastic material, covering the tubular connecting portion at its upper end. The bird protection is therefore very simple and inexpensive and constructed by the use of rod-shaped cover made of acid-resistant plastic, very durable and low maintenance. Bird protection prevents birds from entering the chimney module and clogging it. Particular advantages of bird protection arise in connection with the base part described above, since this has only a small inspection opening and thus blockages by penetrating into the chimney pipe module objects - such as birds - should be avoided as possible.

Further preferred embodiments emerge from the subclaims.

5. Detailed description of preferred embodiments

Hereinafter, preferred embodiments of the present invention will be explained in detail with reference to the drawings.

Fig. 1 shows a chimney pipe module 1 with a pipe section 10 and an adjoining top sleeve portion 20. The entire chimney pipe module 1 is made in one piece and consists of a plastic material, preferably an acid-resistant plastic material, in particular PVDF (polyvinylidene fluoride). The chimney pipe module 1 is therefore suitable for the construction of wet chimney systems, in which the combustion gases condense for heat recovery and environmental protection on the inner wall.

In the sleeve portion 20 is preferably a seal (not shown) is provided, which seals the chimney pipe module 1 with another chimney pipe module 1, which is inserted from above in the sleeve portion 20. For ease of assembly, the sleeve portion 20 further comprises at the top centering tabs 40, which are bent upwards and to the side and thereby quasi enlarge the diameter of the sleeve portion 20. They facilitate the centering and joining together of several chimney pipe modules 1 in a masonry floor-high chimney.

As in FIG. 1 can also be seen, the chimney pipe module 1 a arranged at the upper end of the chimney pipe section 10 Feuerungsanschlussrohr 30, to which a fireplace, for example, a gas floor heating can be connected. The Feuerungsanschlussrohr 30 open to the hollow chimney pipe section 10 and the hollow sleeve portion 20 of the chimney pipe module 1, so that combustion gases can be introduced into the chimney pipe section 10.

Furthermore, the chimney pipe module 1 has three fastening elements 60 which protrude perpendicularly from the chimney pipe module and have a generally rod-shaped design are. The fasteners 60 are shown in detail in FIG Fig. 4 shown and serve to firmly anchor the chimney pipe module 1 in a chimney. For this purpose, they have an anchoring area 64 at their front end, as well as a stop 62 in order to position the chimney pipe module 1 exactly within the chimney shaft. The anchoring region 64 may be provided with ribs or circumferential barbs to ensure a secure anchoring of the chimney pipe module in or on a chimney stone. For this purpose, the anchoring region 64 may also consist of a different plastic material than the chimney pipe module 1.

Furthermore, the chimney pipe module 1 has a plurality of spacers 50, which are preferably made of steel or plastic rings, and which are compressed during insertion of the chimney pipe module 1 in a chimney shaft 130, as in Fig. 2 shown to center the chimney pipe module 1 in the chimney tray 130.

The chimney pipe module 1 has an overall length of 2 to 5 meters. Thus, the chimney pipe module 1 is approximately as long as the floor height of the building in which it is used. In particular, length 1 of the chimney pipe module 1 is longer by the amount than the storey height of the building, which is necessary for the mating of two chimney pipe modules 1 and the expansion-related length compensation. Thus, only one chimney pipe module 1 must be used for each floor, which results in the above advantages in terms of simple and inexpensive installation, as well as the prevention of assembly errors and the prevention of leaks. Preferred overall lengths of the chimney pipe module are 2m - 4m, 2m - 3m and 2.3m - 2.8m. So it is optimally adapted to common room heights of about 2m - 5m.

Fig. 2 shows the chimney pipe module 1 Fig. 1 in partially installed condition. It can be seen that the spacers 50 are compressed and center the chimney pipe module 1 inside the chimney shaft 130. The chimney shaft exists of several masonry chimney blocks 100, 110, 120 of a conventional mineral material, such as brick, clay, chamotte or the like.

The fact that each standardized chimney pipe modules 1 are used in defined chimneys 130 and with defined fastening and centering, the wall thickness of the chimney pipe module can be made very thin and possibly as a flexible flexible tube. Unlike, for example, the retrofitting of old fireplaces or individual chimney systems made of individual components, each chimney module only has to support itself and otherwise take no further support function. Due to the smaller wall thickness of the chimney pipe module on the one hand expensive acid-resistant plastic is saved and on the other hand improves the heat transfer.

The in Fig. 2 top chimney, which is referred to below as the first chimney 100, is particularly adapted to the chimney pipe module 1. In addition to the usual upper flange portion 102, a lower flange portion 104 and a passage opening 106, like any ordinary chimney block 120, it additionally has a recess 108 for receiving at least a portion of the Feuerungsanschlußrohrs 30 at the upper 102 or lower flange portion 104. In the in Fig. 2 1, the upper flange region 102 has a semicircular section-shaped recess which has a larger diameter than the firing connection tube 30. However, the recess could also be arranged in the lower flange region 104.

As in Fig. 3 to see, the first chimney 100 further has three recesses 105 for attaching at least one fastener 60 between two chimney blocks 100, 110.

The entire chimney system is now manufactured as follows: First, a chimney 120, 140 is placed, then it will be described in more detail below Base 400 mounted and secured with another patch chimney stone 120, 140. Then further chimneys 120, 140 are placed on each other, and glued or bricked on each other to form a hollow chimney shaft 130. The chimney stack 130 serves to later receive the chimney pipe module 1 and to provide a region 106 between the chimney pipe module 1 and the inner wall 132 of the chimney flue through which fresh air can be drawn for combustion.

The chimney shaft 130 is bricked up with chimney blocks 120, 140 to below the height of the Feuerungsanschlußrohrs 30. Then, the first chimney 100 is placed, which has the recess 108 for the Feuerungsanschlussrohr 30, and the Aussparrungen 108 for the fasteners 60th

In this state, a chimney pipe module 1 for the underlying floor (EC) is now inserted from the first floor through the chimney hole in the chimney hood 130, so that the Feuerungsanschlussrohr 30 is at least partially received in the recess 108 of the first chimney block 100. At the same time, the attachment areas 64 of the attachment elements 60 are inserted into the corresponding recesses 105 in the upper flange area of the first chimney block 100. The stops 62 then abut the inner wall 132 of the chimney block 130.

When inserting the very long chimney pipe module 1 into the hollow chimney shaft 130, the flexible spacers 50 center the tube section 10 within the chimney shaft 130, so that the lower end 2 can be inserted into the sleeve section 20 with the aid of the centering straps 40. As a result, a gas-tight chimney system for energy-saving wet chimney technology is being built in pieces. Length changes of the chimney pipe module 1 by the thermal expansion are compensated by the sleeve portion 20.

Fig. 3 shows a view from above of a first chimney 100 with just inserted chimney pipe module 1. If the assembly is done so far, a second chimney block 110 is placed on the first chimney 100, the lower flange portion 114 is formed corresponding to the upper flange portion 102 of the first chimney piece 100 , In particular, the upper chimney block 110 is formed so that a corresponding recess 118 is provided for the passage of the Feuerungsanschlußrohrs 30. Furthermore, recesses may also be provided for the attachment regions 64 of the attachment elements 60.

Fig. 5 shows that the recesses 108 and 118 together have a larger diameter than the Feuerungsanschlußrohr 30. This is necessary so that in the area 109 between the recesses 108, 118 and the Feuerungsanschlussrohr 30 preheated fresh air can be sucked to operate a furnace.

In operation, by passing the cold fresh air past the hot chimney pipe module 1, heat of the combustion gases or flue gases 12 is transferred to the fresh air in the region 106. As a result, the flue gases cool 12 and the fresh air is preheated, whereby a large part of the heat energy of the flue gases 12 can be recovered. At the same time, the flue gases 12 condense inside the chimney pipe module 1 and are collected in the base module 400 and neutralized and filtered in the usual way, for example by means of a neutralization box with limestone filling.

In Fig. 6 is a second preferred embodiment of the chimney pipe module 1 and the entire chimney system 101. This embodiment is similar to the first embodiment according to the Fig. 1 - 4th except for the anchoring and centering of the chimney pipe module 1 in the chimney shaft 130. The chimney pipe module 1 is provided for anchoring to a chimney block 140 of the chimney shaft 130 with four fasteners 160, which are formed as U-shaped profiles. These fasteners 160 are, as well as in Fig. 8 represented, in a plane E and arranged at right angles to each other.

With the fastening elements 160, the chimney pipe module 1 can be hung on corresponding longitudinal ribs 142 within the passage opening 134. Other fasteners are not necessary. Here, only three of the four existing fasteners 160 are used. A corresponding chimney block 140 with three longitudinal ribs 142 is in Fig. 8 shown. In this figure, a longitudinal rib 144 of another chimney block 140 is shown in dashed lines, the chimney pipe module to the fourth side (in Fig. 8 upwards) centered. The chimney pipe module 1 has four fastening elements 160 so that it can be used independently of direction (depending on the direction of the Feuerungsanschlußrohres 30) in the chimney. In addition, it can be better injection-molded round if it is symmetrical as possible.

The chimney block 140 has in the passage opening 134 only on three sides of a longitudinal rib 142, so that on the remaining free side of the Feuerungsanschlußrohr 30 can be passed through the chimney block 140. Three longitudinal ribs 142 on the chimney block 140 are also sufficient, since the same Kaminsteintyp can be walled rotated by 180 ° and then ribs 142 on the "missing side" in the chimney shaft 130 are available. This is with the rib 144 in Fig. 8 shown.

Further shows Fig. 8 in that the chimney block 140 can also be equipped as a double chimney block with a further pull or passage opening 132, which can preferably be used for ventilation of the living space.
In Fig. 7 the connection of the chimney system 101 to a flat roof 152 is shown. After inserting the uppermost chimney pipe module 1 from the roof chimneys 140 are still placed, so that at least two stones on the flat roof 152 also protrude. A standard insulation is pulled up around these stones and, if necessary, the chimneys 140 are plastered. On the chimneys 140 is a fireplace cover 154 placed and fixed ceramic. A seal 150 seals the chimney cover 154 upwards. In the chimney pipe module 1, another chimney pipe 2 is inserted, which merges into a bird guard 300, which forms the upper end 330 of the entire chimney system.

The bird guard 300 has for connection to the chimney pipe 2 a tubular connecting portion 310, and rod-shaped cover 320 made of an acid-resistant plastic material. A preferred star-shaped arrangement of the rod-shaped cover members 320 on the bird guard 300 is shown in FIG Fig. 10 shown. Such star-shaped arrangements of rod-shaped cover members 320 are formed as sprues in the production of injection molded parts and are usually thrown away or re-processed into granules. Here, individual sprue stars or several welded one above the other to a plastic chimney pipe and prevent so that birds or objects can penetrate into the chimney pipe.

Fig. 9 shows the situation of the fireplace system at the bottom. Through a special base part 400, it is possible to completely dispense with the otherwise necessary brick fireplace in the basement. The base part 400 is completely made of an acid-resistant plastic material and has a sleeve portion 414, for receiving a chimney pipe, in particular a chimney pipe module 1. So that a chimney pipe module 1 can be easily inserted, the sleeve portion 414 further comprises upward and outwardly bent centering tabs 412.

Furthermore, fastening elements 402 are provided, which are designed as U-shaped tabs and can be supported on the longitudinal ribs 142 of a chimney block 140. The sleeve portion 414 passes through a reduction in a pipe section 404, which extends through the basement ceiling 420.

Connected to this tube section 404 is a flange closure 406 with condensate discharge 408, which in the illustrated embodiment merges into an arc 410 followed by a smooth tube 418. In turn, a hearth in the basement can be connected to this smooth tube 418. If not required, the smooth tube 418 is sealed with a closure lid 420.

The base part 400 is therefore designed so that it extends through the basement ceiling 420, wherein the sleeve portion 414 above the basement ceiling 420 and the flange closure 406 is arranged with condensate drain 408 below the basement ceiling 420. Thus, especially in retrofits can be dispensed with an expensive major breakthrough in the basement ceiling. A small opening with, for example, 160 mm diameter in the basement ceiling is sufficient. For secure attachment of the base part 400 to the basement ceiling 420 and the fireplace blocks 140, it can be additionally secured with a hard foam 416.

The tube section 10 of the chimney pipe module 1 can consist of a smooth tube as well as of a flexible tube with a corrugated wall in both embodiments. As a result, changes in position and direction in the chimney shaft 130 can be compensated. In addition, a flexible tube with corrugated wall has the advantage that it has a much larger surface area, so that the heat transfer between the flue gases 12 and the fresh air is improved. Furthermore, the flue gas is swirled by the corrugated wall whereby the heat gain is improved.
