【摘要】 讨论了生物质气化的机理和反应过程,在生物质热解机理研究、煤热解和垃圾焚烧工艺及设备研究的基础上,提出了一种新的以循环灰为热载体的双床秸秆热解工艺,该工艺的优点是:能源回收率高,利于环保,生产的燃气热值高,可达(10~13)MJ/m3(标准状态)。设计产气量为1 500 m3/h的装置,每年可处理秸秆2.2万t。更多还原

【Abstract】 The mechanism and reaction process of biomass gasification have been discussed,and a new type double bed straw pyrolysis process being put forward on the basis of studying the biomass pyrolysis mechanism,and studying the coal pyrolysis and MSW incineration process and equipment.The said straw pyrolysis process uses the cyclic ash as heat-carrying agent,and has many advantages,such as having high energy recovery rate,being beneficial to environmental protection,boasting high calorific value of produced gas——about(10~13)MJ/m3(standard state).The designed facility has gas-producing capability of 1 500 m3/h,it can process straw of 22 thousand tons in one year.更多还原
