Abstract In this paper, the industrial test of a new kind of coal catalyst developed by Tianjin Cement Industry design and Research Institute was carried out in a 4 500t/d production line which using high calorific value bituminous coal as fuel in South China. Results showed that the clinker quality was improved and the qualification rate of free lime was increased by 8.76% compared with vacant catalyst. The use of coal-combustion catalysts has obvious benefit on the stability of burning system, the coating of inlet chamber decreases and the kiln working condition is improved evidently. The standard coal consumption of unit clinker is reduced by 3.40 kg, and the coal saving rate is up to 3%, which has remarkable economic and social benefits.
