Straw coal gasification warming stove

Abstract

The invention relates to a straw coal gasification warming stove which comprises a stove body (1), wherein a vertical water jacket partition plate (2) is longitudinally arranged in the stove body (1); a positive combustion smoke and fire outlet (21) is formed above the vertical water jacket partition plate (2); a second combustor (13) is internally provided with a positive / reversal combustion conversion turning plate (3); a reversal combustion smoke and fire outlet (22) is formed between the lower side of the vertical water jacket partition plate (2) and the back side of a fire grate (14); a plurality of reversal combustion ventilation fire grate tubes (4) are arranged on the position of the reversal combustion smoke fire outlet (22); smoke dust passing gaps are arranged between the adjacent reversal combustion ventilation fire grate tubes (4); the second combustor (13) is internally provided with a gasification combustion-supporting tube (5); the straw coal gasification warming stove has the advantages that the combustion efficiency of fuels is high, the flue gas purification effect is good ,and the usage cost is low; the straw coal gasification warming stove is convenient to use; the effect is good; the fuel combustion is more fully; smoke dust can be fully burned in the second combustor; discharged flue gas is cleaner; the energy conservation and environmental protection property is better; the fuels are further saved by using the straw coal gasification warming stove; the usage cost is lower; the using effect is better.

Description

technical field

[0001] The invention relates to a heating device, in particular to a heating furnace. Background technique

[0002] At present, the heating furnaces for civil use with forward and backward burning functions are generally equipped with a forward and reverse burning conversion flap in the furnace body, so that the heating furnace can be converted between normal burning and reverse burning according to the needs of use. However, when this type of heating furnace backfires, the smoke needs to pass down through the fuel layer and the fire grate and then enter the second combustion chamber. The purpose of improving fuel combustion efficiency and purifying flue gas. If an induced draft fan is installed at the mouth of the chimney to force the induced air, the use cost will be increased. In addition, the second combustion chamber of this boiler is not equipped with a combustion-supporting ventilation device, so the combustion condition of the smoke in the second co...
