A typical kind of coal with 40% ash and 4% sulfur is studied. It is hard to ignite when the coal is briquetted with the addition of calcium carbide waste at a reasonable Ca/S ratio. Combustion properties of sugar cane waste, coal and their blends are studied on TGA. The ignition temperature is reduced and the combustibility is improved with a small dosage of sugar cane waste. A rational ingredient for coal briquettes is determined, and then it is tested on a bench-scale fixed-bed unit under controlled atmosphere. Experimental results have proven that these coal briquettes can be ignited more easily. Sulfur fixation reaches 45% at Ca/S 1.3--1.8 under 1,250 C.
