中文摘要：

本文对两种典型的生物质燃料在火墙中的放热功率进行了实验。得出了玉米芯和玉米秸秆的放热功率曲线。在相同燃烧条件下,玉米秸秆的燃烧速率和放热功率要远远高于玉米芯。通过用氧气消耗法和二氧化碳产生法两种方法得到计算结果与实验结果进行对比,验证了放热曲线的可靠性,为进一步建立生物质燃料的燃烧模型提供了参考。

英文摘要：

Theoretical basis and calculation method of oxygen consumption method and carbon dioxide generation method are introduced in this paper. Also they are used to predict the heat release rate of fuel when they are burned in hot-wall. The results show that the heat release rate of corn stalk is far higher than corn cob when they are burned in the same hot-wall. Error analysis is done to examine the reliability of the heat release rate curves. These results can be used to provide foundation for combustions model＇s building.
