Power Generation from Coal Gangue in China: Current Status and Development

Abstract

This paper provides an overview on the current status of power generation in China using coal gangue. The government regulation towards the use of coal gangue for power generation is introduced. Emission of pollutants and low thermal power plant efficiency are the two major problems for the power industry firing coal gangue. Particulate matter emission control is a problem due to the high ash content. Sulfur emissions from these units are easily controlled mostly through lime/limestone injection and in-situ capture. Overall, efficient power generation using coal gangue is a promising approach to reduce the use of coal resources and reduce the environmental impacts.
