Application and Optimization of Air-Cooled Dry Slag Removal System in 1×330MW Unit
The 330 MW unit of Donghai Thermal Power adopts the traditional hydraulic slag removal method,which has many problems such as water resource waste,high energy consumption,poor safety,and high maintenance costs.Research and demonstration were conducted on the discharge method of slag in the production process of power plants and the improvement of the comprehensive rate of slag.The hydraulic slag removal system was transformed into an air-cooled dry slag removal system,which simplified the slag removal system and improved energy utilization and boiler efficiency.The air-cooled dry slag removal system has sufficient ash combustion,low carbon content,and retains the activity of the slag,which is conducive to the comprehensive utilization of ash and improves social and economic benefits.It is of great significance for improving the economic operation level of the entire power plant.
