2nd, according to the combustion characteristics of biomass, deslagging and continuous material are controlled whether by the temperature of biomass lower-layer fuel,
Biomass can be made when Indoor Combustion is burnt, the burning zone of multilayer is formed, the superiors are biomass preheating, dry, pre-burning layer, are
The primary combustion of the second layer plays booster action, and the second layer is then primary combustion layer（Characteristics Control according to biological material its
Suitable temperature of the temperature below 800 DEG C）, biomass fissioned in smoulder, decomposed, at the same biomass in burning again
By the airflow influence sent into, air-flow aids in it to burn, and the combustible gas purity that now biomass are decomposited is higher, undermost
Biomass are further fissioned in burning, decomposed, and carry out temperature control to orlop using temperature sensor（Control temperature is 800
Between DEG C -1000 DEG C）, after ignition temperature reaches design temperature value, temperature sensor transmit a signal to motor-operated control valve and
The motor of blanking device, motor-operated control valve is opened, and starts deslagging, while feed arrangement starts charging, into the biology in body of heater
Matter forms layered circulation burning, it is to avoid temperature is too high to cause the impurity, the combustible gas of generation such as biomass carbonated generation carbon dioxide
Purity is higher；
3rd, the combustible gas produced after biomass combustion in uphill process in dirt pocket, is sprayed after through an air outlet
Water or limewash are lowered the temperature and are dissolved to it so that the dust contained in combustible gas is discharged in being dissolved in shower water or limewash
Outside dedusting room；
4th, the handicapping aerofoil at an air outlet, after combustible gas is through an air outlet, certain resistance is played to combustible gas
Gear is acted on, the time for delaying it to reach secondary air outlet, and on the direct jet of combustible gas to dirt pocket side wall, on the wall of dirt pocket side
Filter dedusting further is carried out to it, enhance the dust removing effects of dirt pocket.
