Burst Analysis of the Waterwall Tube in Circulating Fluidized Bed Boiler
Yang Jie;Wang Libo;
The burst tube and the parallel tubes of one boiler waterwall are analyzed by means of macro examination,metallographic examination,tensile testing at room temperature,scanning electron microscope and energy spectrum analysis. The results show that the waterwall tube burst and the butt weld cracking are due to hrdrogen induced loss of the scale layer in tube inner wall.
