摘　　要：燃池是一种利用生物质阴燃的新型加温方式.为探究不同含水率的水稻秸秆对燃池供热的影响,利用自主设计的实验台(600mm×560mm×300mm)进行含水率对水稻秸秆阴燃时内部特性影响实验.结果表明:不同含水率的稻秆均近似呈现整体阴燃传播形式;不同含水率对稻杆阴燃前期干燥过程以及持续300℃以上高温的时间影响显著;对稻杆内部的最高温、内部炭氧化过程以及失质量特性等影响均较小.Burning pool is a new type of heating method that uses biomass smoldering. In order to explore the effect of rice straw with different water content on the heating of the combustion pool, an experimental platform (600mm×560mm×300mm) designed by ourselves has been used to test the effect of moisture content on the internal characteristics of rice straw smoldering. The results show that the rice straws with different moisture content all showed the overall smoldering propagation pattern;different moisture contents had significant influence on the drying process of rice straw and the duration of high temperature above 300°C;the highest temperature inside the rice straw, internal carbon. The effects of oxidation process and weight loss characteristics are small.
