摘　　要：锅炉二次风配风方式对炉内煤粉的燃烧有很大的影响。本文在机组负荷分别为400 MW左右、450MW左右和560 MW左右时,进行了二次风配风方式分别为均衡配风、正宝塔配风和束腰配风等三种配风方式的优化调整试验,在兼顾锅炉经济性和环保特性的前提下,确定了优化的二次风配风方式,对大容量、燃烧劣质煤锅炉的优化运行具有指导意义。Secondary air distribution mode Of the boiler has a great influence on pulverized coal com- bustion in furnace. In this paper, air distribution optimization adjustment tests with different air dis- tribution modes such as balanced, pagoda and beam were conducted under loads of 400MW , 450MW and 560 MW. Optimized air distribution modes with better environmental protection and e- conomic performance were obtained with the test results. The paper is instructive to the optimized operation of high capacity boilers burning low quality coal.
