Description

technical field

[0001] The invention relates to a stove, in particular to a stove for gasifying and burning biomass fuel. Background technique

[0002] At present, there are generally two technical solutions for biomass stoves, one is semi-gasification combustion, and the other is full gasification combustion. Full gasification is to put the biomass raw material in the gasifier, and produce combustible gas (including carbon monoxide, hydrogen, methane, ethane, etc.) can. For example, the gas-making furnace patent (ZL02277000.3) technology belongs to this type of furnace. Although it is currently the most advanced in the gasification furnace technology, there are still three technical deficiencies in the following aspects: a. It needs to be equipped with a fan; b. tar; c has certain requirements on the use of raw materials. The technology of the semi-gasification stove mainly adopts the method of adding sufficient material at one time and burning from the top to the bottom...
