Abstract

The invention relates to a coal gasification normal atmosphere water heating horizontal boiler, comprising a boiler body, an air blaster, an air guide device, a desulfurization and dust collecting device, a coal gas generating area, an open fire igniting area, the upper part of the boiler body is a sleeve water-jacket pipe hot water circulating device, the lower part is arranged with a sealed slag removing pool, the coal gas generating area is arranged with an anti-explosion coal gas guide pipe above and it is communicated with the adequate water sealed place of the water sealed groove, the coal gas generating area is arranged on the front outer place of the boiler body, a sealed separating arch is arranged between the coal gas generating area and the open fire igniting area, the arch is arranged with one or two smoke via burning holes above. The open fire igniting area is arranged at the front of the boiler body and it is separated from the burning room, and a round or elliptical or square flame spraying hole is provided. The invention makes the coal gasified to burn, therefore it is burned more sufficiently and the efficiency is improved with energy saved, the operation is easy and the desulfurization and dust collecting effect is extinctive.

Description

(1) Technical field [0001] The invention relates to a boiler, in particular to a coal-fired gasification atmospheric pressure hot water horizontal boiler which converts loose coal into gas and uses it as fuel. (2) Background technology [0002] At present, the boiler is still the leading equipment for thermal power production, and the fuel used by the boiler is basically coal, specifically, coal or coal powder is fed into the boiler for combustion. At present, the main problem of coal-fired boilers is that the combustion efficiency is not high, which is a great waste of energy. There are also a large amount of slag and a large amount of soot containing dust, which is a serious pollution to the environment and is urgent. Big problem to be solved. [0003] Although people think of various ways and measures to improve these problems, they have not been fundamentally solved, and the effects are not ideal, and the problems of low combustion efficiency and air pollution have not ...
