一维炉系统的调试实验

Debugging Experiment of One-dimensional Furnace System

为研究一维炉内的燃烧情况,以稻壳粉作为燃料,在一维炉上进行燃烧调试实验,对原稻壳粉和燃烧后的灰分进行热重分析,通过烟气分析仪对尾部烟气的检测结果来判断稻壳粉的燃尽情况,以此来调整风量和燃气量的配比。结果表明:尾部烟气中氧气含量和灰渣中固定碳的剩余量在理论计算的误差范围内,说明一维炉实验台密封性良好,自动化程度高,可以较好地保证实验的准确性。

In order to study the combustion conditions in the one-dimensional furnace,rice husk powder was used as fuel to conduct combustion debugging experiments on the one-dimensional furnace.Thermogravimetric analysis was performed on the original rice husk powder and the burned ash.The tail smoke was analyzed by a flue gas analyzer.The gas detection results are used to judge the burnout of rice husk powder,so as to adjust the ratio of air volume and gas volume.The results show that the oxygen content in the tail flue gas and the remaining amount of fixed carbon in the ash are within the error range of the theoretical calculation,indicating that the one-dimensional furnace experimental bench has good sealing and a high degree of automation,which can better ensure the accuracy of the experiment.
