针对秸秆气化炉运行中填料时易泄露燃气、原料压实不准确、点火不均匀以及入炉空气量不合理等问题,设计了一种以玉米秸秆为原料,带有连续输料机构和原料压实机构的秸秆气化炉.实现了点火控制及入炉空气量的控制.以原料的气化量试验确定原料输入量;以原料气化强度和氧化区温度试验确定原料压实电机电流、入炉空气量及电炉丝点火时间.结果表明:螺旋旋料装置转速20 r/min 时,进料量等于秸秆消耗量;电炉丝点火10 s后通风,持续点火1 min 时达到秸秆气化点火要求;压料电机电流为0.9 A、入炉空气量为2.5 m3/h 时气化强度和产气率最佳.试验研究对气化炉优化和改进具有指导意义.

In order to solve the problems of straw gasifier such as packing easy to leak,raw material compaction unaccurate,gas ignition ununiform,into the air volume unreasonable.A new straw gasifier is designed with corn straw as the raw material,with continuous feeding mechanism and raw material compac-tion mechanism.The control of ignition and amount of air into the straw gasifier are improved.Input of raw materials is determined by amount of raw materials of gasification.In biomass gasification strength and oxi-dation temperature are determined by the compressive strength of raw materials,air flux and electric stove wire into the ignition time.The results show that Spiral screw feeder rotate 20 r/min.The rotation rate of consumption is equal to the straw.Pressure feed motor current is 0.9 A.Charging air volume of 2.5 m3/h when gasification intensity and gas rate is the optimum.Electric stove wire fire ventilation after 10 s.Con-tinuous ignition 1 min to gasification ignition requirements.Experimental study of gafier has guiding signif-icance for further optimization and improvement.
