【摘要】 研究小型层燃炉燃烧实验系统,设计并搭建了生物质多功能实验台,可进行层燃燃烧、室燃燃烧及配风等实验的模拟。同时对水稻秸秆和玉米芯燃料层燃燃烧过程进行了研究,分析了风量对生物质燃料层燃燃烧的影响。研究表明:对床层内部分布的热电偶的温度和整个燃烧过程中床层上方的气体浓度变化进行分析,燃烧过程的温度变化曲线与床层上方气体浓度变化曲线吻合的很好;随着风量增大,燃料燃烧完全所需要的时间缩短,对比于粉碎秸秆,成型的玉米芯燃料更适合在高给风量条件下燃烧。更多还原

【Abstract】 The article studies on the experimental system of miniature layer combustion burner,designing and putting up biomass multi-function experimental table,this experimental table can be used to simulate the experiments of layer combustion,chamber combustion and air distribution.Emphasizing on process in layer combustion of biomass fuel and analyzing the influence of different air flow to layer combustion.The results show that temperature variety curve is accord with gas concentration variety curve by analyzed on temperature of thermocouple distributed in fuel bed and gas concentration in whole combustion process;burn-off time is shorter as increasing air quantity;comparing to cut straw,corn cob is more fit for burning in high air flow.更多还原
