Slag Handling Renovation in China

Zouping Power Plant faced challenges managing slag and wastewater due to inefficient transportation and treatment processes. The long distance between boilers and dewatering bins, along with the need for multiples supporting equipment, resulted in high power consumption, increased labor demands, substantial maintenance costs, and risks of wastewater leakage. To address these issues and improve slag treatment efficiency, the plant constructed a new slag silo located between the boilers to mitigate storage constraints and reduce transportation distance. In addition, the slag conveyor system was upgraded to transport and dewater slag simultaneously.
