Calcium carbide slag,an industrial solid waste rich in Ca(OH)2,has multiple economic,environmental,social,and ecological benefits as a substitute for limestone in flue gas desulfurization at thermal power plants.This paper discusses and compares the current in-furnace desulfurization technology and flue gas desulfurization technology using calcium carbide slag in China.It elaborates on each technology from the principles of desulfurization and influencing factors,and points out the advantages that calcium carbide slag has over limestone.Additionally,it analyzes the problems associated with using calcium carbide slag for desulfurization in power plants and proposes solutions.The paper offers reference suggestions for the rational substitution of calcium carbide slag for limestone in flue gas desulfurization at thermal power plants and suggests directions for future development.
