Abstract

Abstract: Longitudinal cracks were found in the drum of 410 t/h circulating fluidized bed boiler (CFB boiler) in a petrochemical self-owned power plant after 7 years of operation. Through studying the hardness and operation conditions near the cracks, the causes of cracks were analyzed in depth and the repair methods of welding cracks were put forward, which could provide reference for the timely repair and proper treatment of similar drum defects.

Key words: CFB boiler, steam drum, welding crack, repair
