摘要
本文为切圆燃烧炉膛的传热建立了一个一维区域模型。在模型中考虑了部分烟气由上而下回流的实际情况.此模型能够反映出沿炉膛高度方向热流和温度分布随炉内工况变化.文中还以1000t/h直流锅炉的双炉膛为例,在IBM-PC/AT机上进行了计算,结果准确,且计算过程极短,可用于锅炉的实时模型中。
A one-dimensional resional heat transfer model of tangentially fired furnaces is presented, which considers partial gas down reflow. Change of heat flux and temperature distribution along furnace height with varying furnace conditions can be reflected in the model. Results of an addinoal calculation with IBM-PC/AT computer of a 1000t/h double furnace once-through boiler furnace as an example has proven accurate with only a short computer time need.
