Problems solved by technology

[0002] There are some disadvantages in the existing conventional reverse combustion boilers, for example: the furnace has a large appearance, the flow of working medium water is not long enough, the heat recovery is not sufficient, its thermal efficiency is about 80%, and the impurity content in the flue gas is high, so there are It is necessary to provide a new type of coal-fired hot water boiler

Abstract

The invention discloses a novel gasification counter-heating water boiler, which comprises a boiler shell, a boiler furnace, a fire grate, a coal door, a poke door, an ash door, a smoke channel, a chimney and an automatic control device, and is characterized in that: the coal door, the poke door and the ash door are all visible sealed furnace doors with micro positive pressure, and the novel gasification counter-heating water boiler further comprises a circumferential multipoint air distributing device, a wet desulfurizing dust remover of a built-in pipe burying afterheat recycling device, and a smoke gas afterheat recycling air heater. The novel gasification counter-heating water boiler has the advantages of less equipment investment, low running cost, automated operation, 85 percent of the boiler thermal efficiency, low pollutant discharge and boiler modularization, and can be widely used in places needing small-scale heat supply such as residential houses, bath centers, factories, hotels, government agencies and the like.

Description

technical field [0001] The invention relates to a novel coal gasification reverse combustion boiler, in particular to a coal gasification reverse combustion hot water boiler. Background technique [0002] There are some disadvantages in the existing conventional reverse combustion boilers, for example: the furnace has a large appearance, the flow of working medium water is not long enough, the heat recovery is not sufficient, its thermal efficiency is about 80%, and the impurity content in the flue gas is high, so there are It is necessary to provide a novel coal-fired hot water boiler. Contents of the invention [0003] The purpose of the present invention is to provide a new type of coal gasification reverse combustion hot water boiler, the boiler is clean, high thermal efficiency, easy to operate, safe and reliable, less equipment investment, low operating costs. [0004] In order to achieve the above object, the present invention adopts the following technical solutio...
