[0003] The existing biomass gasification furnace is only once carbonized, so the calorific value is low, the hydrogen content is low, and the key is that the oxygen content is high. Combustible gas is with tar, and the combustible gas must be defocued before power generation, hydrogen production, etc. Water washing is generally used for defocuing, but the defocuing effect is very poor, and water washing can only remove 60% of tar. During the operation of power generation, tar can also block the air valve, pipeline or cylinder, which is very unfavorable to production. The best is to use electrostatic defocuing equipment, and the defocuing rate can reach 98%. But when the oxygen content in combustible gas is higher than 1%, the defocuing equipment will explode, which is also the bottleneck that biomass gasification furnace has not been widely applied. The biomass and excrement hydrogen production device of electric and gas mixed heating changes the combustion history of biomass gasification furnace, breaks through from once carbonization to multi-layer carbonization, so that the calorific value of combustible gas is increased by several times, the hydrogen content is also increased by several times, and the oxygen content is also reduced by several times, generally not more than 0.3%.
