As a major energy consumer, cement production industry generates a large amount of waste heat during the clinker production process. There are also lots of dust and sulfur dioxide and nitrogen oxide emission accompanying with the waste heat loss, which are aggravating the eco-environment. It is necessary to develop new energy-saving technologies and push the waste heat utilization in cement industry to improve the utilization rate of waste heat from cement. In this study, an exergy efficiency
