摘  要：
根据生物质气化原理,针对目前气化炉产气热值低和存在焦油的问题,设计了一种内燃加热式气化炉。内燃加热式气化炉优于已有的固定床气化炉、流化床气化炉;类似于下吸式固定床气化炉,热解气中焦油含量低;设置以热解气为燃料的内加热系统,减少了空气入炉量,提高了热解气热值。内燃加热式气化炉是将生物质气化与焦油的催化裂解集于一体,不需要再为催化裂解提供热源。

摘  要：
Many problems of gasifiers,such as the heat value produced by gas is very low and much tar remains in the gas during the process of operation.Focusing on these,a new internal combustion type heating gasifier was designed according to the principle of biomass gasification.This type is superior to the fixed bed gasifier and the fluidized bed gasifier,which already existed.Similar to the down draft fixed bed gasifier,the tar in the gas content is very low.By designing an internal heating system taking gas as the fuel,the quantity of the air entering the gasifier was reduced,and the quality of the gas was improved.This gasifier combines biomass gasification and catalytic cracking together so that there is no need to provide the heat source again for catalytic cracking.Inner rotary mechanism,snake pipe internal combustion heat exchanger device,atomization humidification equipment and so on make the gasifier perform well.
