摘　　要：从四角切向燃烧炉内空气动力工况及运行参数方面分析炉膛结渣的原因,并具体结合125MW、660MW锅炉燃烧器的设计特点,利用数值模拟计算及现场试验方法,研究了偏转二次风对炉内结渣的影响。研究结果说明:偏转二次风的角度应控制在15°以内。In the view of aerodynamic fields and operating parameters in furnace, the slagging reason of tangentially fired boiler in operation and anti-slagging measures are introduced. Especically, numerical simulations and field-tests research the effect of using biased secondary air for slagging in furnace for 125MW and 660MW units. The result shows that the angle of biased secondary air should be less than 15°. Figs 5 and refs 9.
