摘　　要：分析了进口等径三通对过热器管流量分配的影响 ,建立了过热器壁温计算模型 ,并以华能阳逻电厂 4号炉高温过热器爆管为例 ,对涡流效应的大小进行了分析 。On the basis of the reptured tube at the final superheater of No.4 boiler in Yangluo power plant,the “tee junction effect” of terminal header on flux distribution in superheater was analysed,a mathematical model was founded to calculate the tube temperature and evaluate the lifespan of superheater and some measures to prevent eddy current in the area near the tee junction were put forward.

关 键 词：电厂 锅炉 过热器 寿命 涡流效应 等径三通
