Coal gasification smokeless combustion boiler

The utility model discloses a coal gasification smokeless combustion boiler, comprising a boiler body, a gas generating chamber, a burner and a burning chamber. The utility model is characterized in that the gas outlet on the center of the flat pipe sheet I on the upper part of the gas generating chamber is communicated with the burning chamber and is opposite to the burner. The upper part of the gas generating chamber is provided with a secondary wind pipe, and the angle of design is 15-30 degrees. The lower part of the burning chamber is provided with a triple wind pipe, the angle of design is 15-30 degrees. The secondary wind pipe on the upper part of the gas generating chamber is communicated to the wind box out of the boiler body from the gas generating chamber. Because two or a plurality of secondary wind pipes are arranged on the upper part of the gas generating chamber, the burner is arranged on the gas outlet of the gas generating chamber, and the triple wind pipe is arranged on the lower part of the burning chamber, compared with prior art, the coal gasification smokeless combustion boiler has the advantages of adapting many kinds of coal, sufficient burning and saving coal more than 20 percents. The dust removing quantity of the chimney is below 80 mg/m3 under standard condition, and theflue gas ringelman blackness is smaller than one grade.
