1The entire device is made of high-temperature refractory materials,24Continuous use at high temperatures without interruption, suitable for large tonnage oil and gas boilers, chain boilers, with stable combustion and high adjustability of boiler load;
2Biomass fuels have high selectivity, including wheat straw, rice straw, corn stover, wood shavings, bamboo powder, sawdust, etc., ensuring fuel supply and effectively guaranteeing stable supply of boiler fuel;
3This gasifier adopts multi-stage air distribution and unique low nitrogen combustion technology. Continuous feeding and production are possible, with stable flames and high temperature range up to1100Biomass fuel has a high combustion rate and thermal efficiency of up to95above;
4No tar, wastewater or other waste discharge. By adopting high-temperature pyrolysis combustion technology, tar and other substances are directly burned in gaseous form, solving the technical problem of high tar content in biomass gasification and avoiding secondary pollution of water quality caused by washed tar;
5The fluidized bed gasifier has the characteristics of rapid heating, frequent start stop, uniform bed temperature, good gas-solid contact and mixing, high gasification intensity, and good comprehensive economy.
