摘　　要：结合 1 2 5MW、660MW锅炉燃烧器偏转二次风系统的设计特点 ,结合数值模拟计算及炉内试验调整改造 ,说明偏转二次风对炉内结渣的影响 ,研究结果建议偏转二次风的角度应控制在 1In 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 in this paper. Especially, 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°.
