Application of the Wind-Water Combined Slag Coolers in CFB Boilers

Abstract:

At present, there have been a lot of accidents happened in the wind-water combined slag coolers of the Circulating Fluidized Bed (CFB) boiler power plants, which usually caused the low-load or even stop of the units along with great financial losses. Comprehensively considering the actual conditions of the domestic CFB boiler power plants, the theoretical analysis and thermodynamic calculation were conducted aiming to solve the specific problems found in the operation. There were new designs and retrofitting measures in the integral structure and some key components, such as the slag inlet-tube. The operation effect of the slag coolers, i.e. the stability and heat-recovery efficiency etc., were significantly improved by retrofitting the devices.
