摘　　要：根据纯几何相似模化理论对某 30 0 MW引进燃烧技术 ,锅炉按 1∶ 13.9比例缩小建立模型试验台。通过对不同二次风反切角度、反切层数及其组合反切方式下的炉膛、烟道中的气流、颗粒流动特性进行了试验研究和数值模拟 ,得到了不同二次风反切方式下炉内气流、颗粒运动规律 。A 1/13.9 model utility boiler has been set up. Experimental investigation and numerical simulation of gas-solid flow characteristics in furnace and horizontal gas pass have been carried out while counter-off-setting auxiliary airs are admitted into furnace with different angles, tiers and etc. Therefore, reasonable results about overall gas and solid flow patterns have been obtained under different counter-offsetting auxiliary air conditions, and a new technique of counter-offsetting upper-half auxiliary airs progressively has been presented.
