摘要：
Coal waste and coal slurry are the largest industrial waste generated from coal preparation plants. This paper describes a method to make clean coal briquette with coal waste and coal slurry. Two binders were used during the coal briquette making process. hi addition, a mixture of cacium hydroxide and coal fly ash was added into the formulation acting as a sulfur retention agent. The results show that coal briquette strength and sulfur retention were significantly improved. For example, both wet strength and falling strength reached 99%. The sulfur retention is about 55.41%
