Abstract

The mechanical performance, morphology characteristic and energy spectrum have been carried out for burst superheater tube in Zhanjiang biomass power plant in this article. The burst mechanism lies in change of mechanical performance, uneven distribution of failure spots, uneven dissolution of alloy composition and the combined effect of K–Si aggression.
