Smokeless burning technique and equipment with fire fontanel being setup inside furnace

Abstract

A smokeless combustion device with fire stack in furnace consists of destructive distillation gasification combustion chamber, the second combustion chamber, top fire grate, bottom fire grate, fire stack in furnace, firepot, heated surface and fender. The extensive fuel materials such as raw coal, bulk coal, section coal, wood, straw and agricultural wastes can be used as fuel material of said device.

Description

technical field [0001] The invention relates to solid fuel combustion equipment, in particular to civil boiling water furnaces, water heaters, organic heat carrier boilers, steam boilers and kilns that use coal and biomass as fuel. Background technique [0002] In my country's energy structure, coal is the primary energy source and is mainly used as boiler fuel. For a long time, coal-fired equipment generally has the phenomenon of insufficient combustion, low thermal efficiency, serious waste of coal resources, and serious pollution of the atmospheric environment. Environmental pollution has become a major problem in the current development of our country. my country's "Eleventh Five-Year Plan" put forward two goals, that is, in the next five years, the growth of unit GDP, energy consumption should be reduced by 20%, and the discharge of pollutants should be reduced by 20%. To drop 10%. Premier Wen Jiabao of the State Council emphasized in his important speech at the Sixth ...

Problems solved by technology

However, the disadvantages of this type of boiler are that the ignition conditions are not good, the ignition and combustion are slow, and the coal types are narrowly applicable.
