摘　　要：高温型煤复合添加剂,其最佳配方为:乾陵石灰石的添加量为10%,改性氢氧化钙的添加量2.5%,含铁辉石的添加量5%,氧化镁的添加量为2%,碳酸锶的添加量为1%,玉米秸秆粘结剂的添加量为15%,该配比制备的型煤在1200℃时固硫率达56%。该型煤的跌落强度高,且具有防水性。A new kind of briquette compound additives is developed. The optimum formulation is that the dosages of the six additives of qianling limestone, calcium hydroxide, the mineral contained iron, Mgo, Srco3 and the corn straw binder（against the mass of raw coal）are 10% ,2.5% ,5% ,2% ,l%and15%. The prepared briquette fixingsulfur efficiency of the sorbent reaches 56% at 1200℃ for 60min combustion under the optimum formulation. The briquette intensity of falling off is higher and the briquette has the quantity of proofwater.
