Abstract

A heating boiler including a housing having a jacket chamber on the lateral upper and rear surfaces for a water heat carrier, a loading door on the front, an air supply adjustment door, a grate shelf, a solid fuel combustion chamber characterized by the presence of secondary air on the front chamber housing, the presence of a lower secondary air chamber, the presence of an additional exhaust gas combustion chamber, the presence of a solid exhaust fuel lower combustion chamber at the top, and the presence of an inlet pipe secondary air with flame arresters, combined with the front secondary air chamber, the presence of an upper exhaust gas guide for directing them through the exhaust chamber.

Description

The utility model relates to energy and can be used to heat individual and industrial premises and other technological needs.

Known heating apparatus RU 102765 U1 related to thermal technology and can be used to heat residential buildings, industrial premises and individual residential buildings. A heating apparatus comprising a combustion chamber with a ceiling in the shape of a visor, with a loading door in its upper part and a grate, an ash chamber with a drawer, a chimney, cold water supply and hot water outlets, There is a cavity between the walls of the housing, the combustion chamber and the ash chamber for the coolant: air or water, when filled with water, a water jacket is formed.

The disadvantage of this heating apparatus is the rapid combustion of one fuel bookmark, insufficient fuel combustion, leading to its incomplete combustion and release of unburned combustion products (soot) into the atmosphere, (RU 102765 U1 www1.fips.ru)

The task to which the claimed utility model is directed is expanding the possibility of using solid fuel for heating purposes, increasing the economy and efficiency of use, and reducing emissions into the atmosphere.

Disclosure of a utility model.

The stated problem is solved with the help of a heating apparatus consisting of a housing, on the lateral upper and rear surfaces of which there is a camera - shirt, for water coolant, on the front of the housing there is a loading door, an air supply adjustment door and a front secondary air chamber, inside the housing between the jacket and a secondary air chamber there is a solid fuel combustion chamber, in the lower part, a shelf for grates, a lower secondary air chamber, at the top of the combustion chamber there is a lower separating the exhaust gases above it, secondary air supply pipes with flame arresters connected to the front secondary air chamber, above them there is an exhaust gas combustion chamber and an upper exhaust gas guide for directing them through the exhaust chamber into the chimney, The main difference from existing analogues is that solid fuel combustion chamber, an additional exhaust gas combustion chamber, by supplying heated secondary air through pipes with flame arresters, connected to the front chamber which in turn, connected to the lower chamber, The technical result of the claimed utility model consists in efficient heating of the coolant by burning solid fuel and burning exhaust gases - soot emissions are reduced, carbon monoxide (CO) and hydrocarbons (CnHm) are completely absent in the exhaust gases, this complete combustion of fuel, efficiency increases up to 80%, fuel consumption decreases from 2 to 16 times, fuel costs are reduced, the amount of ash is reduced, emissions of unburned products are reduced into the atmosphere bestow which fuel for combustion may be any wood fuel. any fraction, about also combustible solid wastes of industrial production, for example chipboard and tires.

The metal of which the claimed utility model is made is designed to work in an aggressive environment, it is covered with a multilayer shirt consisting of iron oxide (several microns), carbon and resins. The boiler is not clogged with soot from the inside and is constantly washed with creosote, resins and other fuel components, which is significantly extends product life

14 - chimney

15 - branch pipe

16 - return pipe fitting

17 - secondary air

18 - exhaust gases - pyrolysis gas

19 - exhaust gases after re-combustion Implementation of a utility model.

The claimed heating boiler operates as follows, in the solid fuel combustion chamber (6) through the loading door (3), the fuel is placed and fired, after the boiler is ignited, heated and then put into operation, in the solid fuel combustion chamber (6) with a lack of oxygen and exposure to low temperatures (250-350С °), the process of gasification of fuel occurs - pyrolysis, the resulting pyrolysis gas (18), which rises, bypassing the lower guide (9) is connected to the oxygen of the heated secondary air (17). which is fed through a system obtained by connecting the lower, front, secondary air chambers (8), (5) and the secondary air supply pipe with flame arresters (10), ignites and burns in the exhaust gas combustion chamber (11), after which the exhaust gases after repeated of combustion (19) bypassing the upper guide of the exhaust gases (12), is sent to the chimney to the chimney (13) and goes into the chimney (14). In the process of burning pyrolysis gas, a large amount of heat is generated. The heat obtained from double combustion is transferred through the heat exchange surfaces to the boiler water in a jacket (2) located on the side, back and top surfaces of the boiler.

Claims (1)
