摘　　要：通过模拟在某燃烧铁法次烟煤的600 MW机组锅炉中掺烧神华煤的分层混煤燃烧过程,分析了在掺烧不同层数神华煤时炉膛内速度场和温度场的分布,研究了锅炉内掺烧神华煤的层数对炉膛出口烟温和炉内结焦的影响,在保证锅炉安全运行的前提下给出了最优的分层掺烧方式,可供同类型锅炉设计和运行时参考。The layered-combustion process of mixing Shenhua Coal on Tiefa sub-bituminous coal in 600MW wall-type tangential boiler is simulated, analyzed the distribution of velocity and temperature area in furnace when the different layers of Shenhua Coal is fired in furnace, researched the effect of different layers Shenhua Coal combustion on flue temperature at furnace outlet and furnace slagging, and gave the optimal way of layered-combustion on the condition of the safe operation of the boiler. It is available reference for designing and operating on the same type of boiler.
