| 摘 要： | 对某电厂440 t/h超高压循环流化床(CFB)锅炉燃烧情况进行模拟计算,计算结果和运行结果吻合很好。通过模拟不同一二次风比例、上级二次风位置、过量空气系数对CFB炉膛温度、SO2及NOx排放分布的影响,分析运行操作参数合理性,为440 t/h CFB锅炉的运行优化提供理论依据。

| Abstract: | Simulated calculation of combustion situation in a 440 t/h supercritical pressure circulating fluidized bed(CFB) boiler in one power plant has been carried out,calculation result talies very well with the operation result.Through simulating the influence of various ratio of primary and secondary air,position of upperlevel secondary air,coefficient of excess air,upon furnace temperature of the CFB boiler,and distribution of SO_2 and NO_x emission,the reasonable optimality of operational parameters has been analysed,providing remedial basis for optimizing operation of 440 t/h CFB boilers. |
