School of Environment, Guangxi University, 530004, Abstract Grey relational analysis of grey system theory was applied to study the relationships between the heat consumption of clinkerandproduction process parameters which base on the actual data of 2500 t/ d clinker production of a company, and discuss the ways of new dry process cement technology optimization and energy-saving technologies, and then the industry practice and optimization were implemented. The results showed that the degree of relation between the clinkerheat consumption of clinker and production process parameters is high which was analyzed by grey relational. Withoutsacrificingoutput and quality ofclinker to reduce heat consumption of clinker by optimizing ingredients of the clinker proportioning, reducing the pulverized coalash, reasonable controlling the parameter of clinker firing system, improving theresidence time ofmaterial in precalciner to bustiondegree of coal andimproving positionrateof materials and others integrated approach. After industry practice and optimization, the heat consumpt
