Description

FIELD OF THE INVENTION

The invention relates to the field of production of boilers, in particular to outdoor boilers, and can be used in systems with individual heating for buildings of different heights and located outside the building.

State of the art

A boiler plant is known, comprising a boiler equipped with a contact air heater and an economizer, connected in parallel to the supply and exhaust lines to the heating paths of the heat network and the surface heat exchanger, the heating path of which is connected to the contact air heater and equipped with a flow regulator, and the economizer is in communication with the boiler supply line, the installation also contains air temperature sensor (see AC SU 1666855, class F22D 1/36).

The disadvantage of this boiler installation is the high cost of its production.

Known boiler installation for external use, containing a thermally insulated fire tube boiler with nozzles of the forward and reverse water lines, a combustion chamber into which the burner nozzle, a chimney are introduced, while it is placed in a thermally insulated casing having openings for external air intake, equipped with shutters with actuators moreover, the boiler in the upper part is equipped with heat-releasing fins for heating the air, an air temperature sensor located inside the casing in the immediate vicinity of the burner device and appointed to manage the drives blinds (see. US Pat. RU №2349844, cl. F24N 1/28, publ. 20.03.2009 city).

The disadvantage of this boiler plant is the high cost of generating heat.

A well-known outdoor boiler containing a gas burner, a boiler heat exchanger, a three-way valve with direct and reverse lines, a chimney, while at the base of the chimney a hatch for cleaning soot and a condensate pipe is installed, and the building heating system contains a vertical riser connected to a straight a boiler line, a deaeration expansion tank, distributing risers with heating devices, a return line to the heating system, a circulation pump, a mud filter (see Condensing boiler l, RGU-M1 operating manual for Ca 2.574.023. RE of Starorusspribor Plant OJSC, 175200 Staraya Russa, Novgorod Region, Mineralnaya St. 24).

The disadvantage of this boiler is its high cost and the cost of heat production, low efficiency.

The closest in technical essence and the achieved positive effect and adopted by the author for the prototype is a hot water boiler containing a fire tube part with an atmospheric gas burner device, a direct and return line, a chimney base with a soot cleaning device and a flow restrictor, while the fire tube part with an atmospheric gas burner device, direct and return lines, the base of the chimney with a device for cleaning soot and a flow restrictor are placed inside a thermally insulated housing, the last one is additionally equipped with a door for servicing the gas burner device and a grill for external air intake, and an automatic thermostatic shut-off and control valve is installed in the straight line of the boiler (see St. PM PM No. 311161, class F24H 1/28 of 03/19/2001 )

The disadvantage of this boiler is its limited functionality, namely the impossibility of using atmospheric and blast burners.

Disclosure of invention

The objective of the invention is the development of an outdoor boiler with versatility, namely the possibility of using both atmospheric and blast burners while reducing the cost of boiler production and simplifying installation work during its assembly.

The technical result that can be obtained using the present invention is reduced to versatility, namely, the possibility of using both atmospheric and blast burners while reducing the cost of boiler production and simplifying installation work during its assembly.

The technical result is achieved using an outdoor boiler containing a thermally insulated body with a service door, an air intake grill, a fire tube boiler placed in it, a chimney base, a soot hatch for cleaning soot, direct and return lines, a gas burner, and it is additionally equipped with a heat insulated a panel for attaching a blast burner, made with the possibility of interchangeability, and under the furnaces of a fire tube boiler is made of heat resistant materials.

Brief Description of the Drawings

In FIG. outdoor boiler, general view.

The implementation of the invention

The outdoor boiler contains a thermally insulated housing 1 with a door 2 for servicing and an air intake grill 3 for external air to enter combustion, while a thermally insulated fire tube boiler 4 is installed inside the thermally insulated housing 1, comprising a heat exchanger 5, a furnace 6, a chimney base 7 with a hatch 8 for soot cleaning, while the heat exchanger 5 contains a straight line 9 and a return line 10, and the furnace 6 contains 11 under the furnace 6, made of heat-resistant refractory materials, heat-insulated panel 12 fixing the blast burner 13, made with the possibility of interchangeability, and a removable thermally insulated panel 12 of fastening the blast burner 13, is fixed in the furnace 6 with the help of pins (not shown in Fig.).

The outdoor boiler operates as follows.

The blast burner 13 generates heat, the flue gas stream is washed under the furnace 11 6, made of refractory materials, heats it to high temperature and swirls the furnace 6 while swirling, the heat exchanger 5 of the fire tube boiler 4 removes cooled flue gases to the base of the chimney 7 and then to atmosphere, and the external air for combustion enters through the intake grill 3, the coolant enters the outdoor boiler through the return line 10 of the boiler, is heated in the furnace 6, heat exchanger 5 of the fire tube boiler 4 and in a straight line 9 the heater is supplied to the heating system (not shown in the FIG.), and if it is necessary to switch the outdoor boiler to work with an atmospheric burner (not shown in FIG.), a blow burner 13 is removed, a replaceable heat-insulated panel 12 and instead of this panel 12 are installed on the same studs atmospheric burner, thus, the outdoor boiler becomes universal in terms of applicability of the burners: blast burner 13 and atmospheric.

As a result of testing a prototype of an outdoor boiler manufactured according to the invention, it was possible to significantly reduce the laboriousness and timing of installing a boiler with a hot water supply system to a heated building while cheapening the production of boilers and to produce a universal outdoor boiler for burner applicability: a blast burner 13 and atmospheric ..

The invention in comparison with the prototype and other known technical solutions has the following advantages:

- versatility through the use of a blast burner 13 and atmospheric.

- cheaper production of outdoor boilers;

- simplification of installation work and reducing the complexity of assembling boilers;

- cheaper heat production.
