Study on recovery and utilization of waste heat from continuous drainage of boiler in coal-fired power plant
Through research and analysis of technologies related to the utilization of continuous drainage from the current boiler,address-ing the technical challenges associated with recovering and utilizing the waste heat from continuous drainage in a studied coal-fired pow-er plant boiler,optimization and retrofitting of the existing equipment were conducted.A multi-nozzle atomizing desuperheater was de-signed,enabling 100%recovery and utilization of the working fluid and heat from boiler steam drum continuous drainage in the form of desalinated water,while meeting energy conservation and emission reduction,it achieved high social and economic benefits.
