【摘要】 应用综合热分析仪对秸秆、稻壳、木屑三种生物质型煤的燃烧过程进行分析,研究了生物质成型工艺和不同氧气浓度对不同种生物质燃料燃烧过程及燃烧特性参数的影响。结果表明:与粉末相比生物质型煤的挥发份释放特性指数降低,燃尽特性指数和综合燃烧特性指数均有所提高;随着氧浓度的增加,挥发分初析温度降低,着火点提前,燃尽特性指数和综合燃烧特性指数均有明显提高。更多还原

【Abstract】 The combustion processes of three kinds of biomass briquettes in powder and particle and the influence of craft to the characteristic parameter of combustion process were analyzed by using the comprehensive thermal analysis instrument.The experimental results show that as compared with the case of powder sample,biomass briquette has lower pyrolysis characteristic parameter with an enhanced burnout characteristic parameter and comprehensive combustion characteristic parameter.TG-OSC analyses to combustion processes of three kinds of biomass briquette in different concentration of oxygen(30%-100%) show that with the increasing of the oxygen concentration,the biomass briquette has lower ignition temperature,obviously enhanced burnout characteristic parameter and comprehensive combustion characteristic parameter.更多还原
