Environment-friendly energy-saving normal pressure hot-water boiler

Abstract

The invention discloses an environmental protection, energy-saving and atmospheric hot-water boiler, which comprises the following parts: once wind intake pipe, twice wind intake pipe, spiral blowing pipe and smoke cleaning discharge plate, wherein the once wind intake pipe blows the air into the coal seam through wind basin, which connects the coal seam to combust; the tuyere of twice wind intake pipe displays flat seam shape to increase the wind penetration, which blows the spiral wind to mix the combustible gas and fuel fines with air sufficiently in the combustion chamber. The spiral blowing pipe structure blows wind upwards spirally and leaves the dust under to fall down the bottom, which improves the efficiency of dust removal. The inclined water bladder structure absorbs the surplus dust heat, which improves the heat efficiency. The smoke cleaning discharge plate and circulation structure adsorbs dust further, which improves the efficiency of dust removal.

Description

technical field [0001] The invention relates to a normal-pressure hot water boiler, in particular to an environment-friendly and energy-saving normal-pressure hot water boiler. Background technique [0002] The existing atmospheric pressure hot water boilers have the problems of low thermal efficiency, coal consumption and large smoke and dust. Not only the cost of smoke and dust control is high, but also the operating cost of boiler dust removal is also high, which increases the burden on the user. Therefore, how to provide a An energy-saving and environmentally friendly boiler with high thermal efficiency, low dust removal cost and high dust removal efficiency has become a difficult problem in front of people. Contents of the invention [0003] The object of the present invention is to provide an environment-friendly and energy-saving atmospheric pressure hot water boiler, which can effectively solve the aforementioned problems by adopting the structure of the secondary ...
