Problems solved by technology
[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 air distribution device with high thermal efficiency, low dust removal cost and high dust removal efficiency has become a difficult problem before people

An atmospheric hot water boiler adopts the structure of the primary air inlet pipe, the secondary air inlet pipe, the spiral blowing pipe and the smoke-clearing water plate. The primary air inlet pipe blows air into the coal seam through the air basin and mixes it with the coal seam. After combustion, the air outlet of the secondary air pipe is in the shape of a flat slot, so the penetrating power of the wind increases, and the spiral wind blown out by it can fully mix the combustible gas and fuel fines floating in the combustion chamber with the air to obtain sufficient combustion , which improves the thermal efficiency of the boiler; the invention adopts a spiral blowing pipe structure, and the blown air spirals upward along the flue, and the smoke in the flue is thrown to the outer wall of the flue under its action, so it sinks at the bottom of the flue and can be passed through The dust removal port removes the furnace, and the dust removal efficiency is higher; the invention adopts the inclined water tank structure, which can further absorb the waste heat of the flue gas and improve the thermal efficiency; the invention adopts the smoke removal water plate and the circulating water structure, which can further absorb the smoke Improve dust removal efficiency.
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 air distribution device 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 atmospheric pressure hot water boiler, which can effectively solve the aforementioned problems by adopting the structure of the secondary air pipe and the spiral blowing pipe. [0004] The object of the...
