Definitions

the invention relates to a device for heating water, in particular a hot water boiler, with heat exchangers surrounding the combustion chamber and arranged below the combustion chamber, parallel, plate-shaped heat exchangers which are offset from one another to form an S-shaped flue gas discharge and longitudinal channels for the two edges Have water that are connected to each other via a plurality of transverse channels that run across the flue gas stream.
the combustion chamber is enclosed by plate-shaped heat exchangers; such a heat exchanger also limits the combustion chamber downwards. It is understood that these heat exchangers are subject to considerable thermal stress; in addition, the water volume is comparatively small, which makes temperature control difficult and the elasticity of the system can be impaired.
the object of the invention is to overcome these disadvantages to eliminate and accordingly to achieve in devices of the type mentioned that the thermal load on the heat exchanger surrounding the combustion chamber is reduced and the elasticity of the system and its control options are improved.
the combustion chamber is arranged according to the invention within a double-walled tube, the outer wall of which is formed at the bottom by a plate-shaped heat exchanger, from which the water can be introduced into the wall of the tube via a large number of small openings.
the double-walled tube opens up the possibility of assigning a larger water volume to the combustion chamber in order to make the water temperature control simpler and more elastic.
no thin-walled plate-shaped heat exchangers which are usually less thermally stable, are used, but rather water receiving rooms, the capacity of which depends on the wall thickness of the double-walled tube, which can be chosen to be comparatively large.
a cylindrical tube is preferably used for the combustion chamber (inner tube of the double-walled tube), while the outer tube is formed by a bow-shaped wall part which merges into the edges of the plate-shaped heat exchanger at the bottom.
the large number of small openings for the passage of water into the wall of the tube still have the great advantage that the wall of the tube or the water therein is whirled through. It also ensures that the water in the wall of the pipe can mix evenly.
the hot water boiler is located in a housing indicated by dashed lines 1; it has a combustion chamber 2 with a burner 3 operated by oil or gas.
the outer diameter of the combustion chamber 2 is determined by a cylindrical metal tube 4. This is enclosed at the top and sides at a distance from a U-shaped wall part 5, the edges of which are watertightly connected to the edges of a plate-shaped, horizontally arranged heat exchanger 6.
the metal tube 4 thus forms the inner wall and the wall part 5 with the heat exchanger 6 forms the outer wall of a double-walled tube which surrounds the combustion chamber 2.
the heat exchanger 6 is the heat exchanger located at the top of a package, which consists of several plate-shaped heat exchangers For example, three heat exchangers 6, 7 and 8 are formed, which are arranged horizontally one above the other and are also laid parallel to the longitudinal axis of the double-walled tube. According to FIG. 2, the heat exchangers 7-8 are also offset from one another in order to achieve an S-shaped flue gas discharge in the direction of the arrows 9. The exit of the flue gases is shown at 10.
each heat exchanger 6 - 8 The two edges of each heat exchanger 6 - 8 are formed by longitudinal channels 11 (parallel to the main axis of the double-walled tube), which are mutually connected via vertical guides 12 for the water.
the longitudinal channels 11 of each heat exchanger 6-8 are connected via a large number of small channels 13, which thus transport the heated water from one longitudinal channel 11 to the opposite longitudinal channel 11.
the water to be heated is fed from below to a longitudinal channel 11 of the heat exchanger 8 and then fed to the channels 13 of the heat exchanger 6 in an S-shaped course. These have 13 small bores with a diameter of about 4-6 mm symmetrical to the longitudinal center plane of the double-walled tube 4-6 in the walls of the channels, which are denoted by 14.
the water heated in the heat exchangers 6-8 therefore flows through the holes 14 arranged in the individual channels 13 in the direction of the arrows 15 into the wall of the double-walled tube. Here it is exposed to the combustion chamber, is further heated and then finally reaches control devices or the consumer via outlet 16 at the top.
the small bores 14 ensure that intimate mixing of the supplied water with the water already in the wall occurs. There is a desirable swirling of the water supplied under pressure and of the water already accumulated in the wall.
the combustion chamber 2 is completely enclosed by a considerable amount of water; towards the outside, the water volume is enclosed by the wall part 5 and a heat exchanger 6. Since the water is under pressure, there is a reinforcement in the form of struts 17 which are distributed over the length of the combustion chamber 2 and which are at an angle and firmly connect the metal tube 4 to the side edge regions of the heat exchanger 6; in addition, a fixed connection between the metal pipe 4 and the heat exchanger 6 can be provided in the middle at 18, e.g. by welding.
the comparatively large volume of water that surrounds the combustion chamber 2 has the advantage that changing temperatures can be better controlled by the consumer; the regulation e.g. bypass is considerably calmed. In addition, the thermal load on the heat exchanger is reduced.
strengthening spacers 19 can be provided between the two walls - parts 4, 5 - which are welded to the metal tube 4 and are firmly connected radially on the outside to strips 20 attached to the inside of the wall part 5.
the wall part 5 is provided with openings 21 in the area of the strips 20, the edges of which can be welded to the strip 20. The openings 21 thus allow access to the strips 20 from the outside (for establishing a firm connection). If the strips 20 are wide enough, the connections or welding points 22 can be offset from one another (FIG. 6).
the boiler according to FIG. 8 additionally has plate-shaped heat exchangers 23 and 24 on its front sides, of which the heat exchanger 24 located on the front front side has a recess 25 for the burner 3.
the heat exchangers 23, 24 also have an inlet indicated at 26, it being understood, however, that only a single cold water inlet for the elements 8, 23 and 24 as a whole is provided, which splits into three ways.
This measure ensures that a water flow through the heat exchangers 23, 24 which is too fast cannot occur and that the measured amount of water heated in these heat exchangers can be supplied to the overall circuit.
the double-walled tube 4, 5 is also shorter at the bottom than at the top; So that the combustion gases can flow favorably into the space between the two heat exchangers 7, 7 located at the top, the double-walled tube 4, 5 is provided at its rear end with an approximately triangular recess 29 (viewed in the side view).
