Development of Pollution Treatment Technologies for Coal Storage Yards in Thermal Power Plants and Case Study

Abstract

The coal storage yard of thermal power plants are exposed to the air, causing problems like polluting the environment, falling short of requirements of eco-protection and undermining safe production. It causes threats in three forms:coal dust, coal pile explosion, and coal pile spontaneous combustion. Wind and dust suppression walls, dry coal sheds, fully enclosed coal sheds and other measures can be used in these yards to prevent pollution in the yard. Pollution treatment in these yards can avoid static dusting of coal and reduce the spread of dynamic dusting. This study interpreted the necessity of environmental treatment of coal storage yards and the development of three main technologies, and conducted detailed analysis and discussion of various environmental treatment solutions for coal storage yards of thermal power plants. This study intends to provide experience and lessons for environmental treatment of coal storage yards.
