摘　　要：一次风微反切技术对解决电站锅炉稳燃与结渣的矛盾,减小残余扭转,以及减少NOX的排放都有显著的效果。通过该技术在380 t/h锅炉的应用,对各种反切角度下的炉内温度场和速度场进行了数值模拟,并分析了它们对结渣和残余扭转的影响。The technology of reverse tangential mode of primary air can effectively solve the conflict between the stable combustion and slagging of the boilers, reduce the residual torsion, and decrease the emission of NOx. Through application of the technology to a 380 t/h boiler, numerical simulations on the temperature field and velocity field within the furnace are conducted with various reverse tangential angles, and their influences on slagging and residual torsion are analyzed.
