摘　　要：本文通过对某300MW四角布置切圆燃烧锅炉在不同省煤器出口氧量及磨煤机投运方式等工况下水平烟道内烟温分布及锅炉效率的热态试验结果的分析,指出了四角布置切圆燃烧锅炉水平烟道内烟温分布随省煤器出口氧量及磨煤机投运方式的变化特点及运行工况的变化对锅炉效率的影响.This paper describes the analysis of the experimental results of the flue-gas temperature distribution in the horizontal flue and the efficiency of a 300 MW tangentially corner-fired boiler in variable load operation. The effect of the oxygen content at the economizer outlet and the operation of coal pulverizing mills on the flue-gas temperature distribution in the horizontal flue was investigated. The impact of variable load operation on the boiler efficiency was analyzed as well.
