boiler tee
2.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.
