燃煤催化剂在高热值烟煤水泥厂的应用

Application of Coal Catalyst in Cement Plant Using High Calorific Value Bituminous Coal

对天津水泥工业设计研究院有限公司开发的新型燃煤催化剂在华南某4 500t/d高热值烟煤生产线上的工业试验,进行了数据检测及分析,结果表明:使用该催化剂后,熟料质量有所提升,游离氧化钙合格率提高8.76%;烧成系统稳定性明显改善,烟室结皮减少,窑工况明显改善;吨熟料标煤耗较使用前降低了3.40kg,节煤率3%,具有显著的经济效益和社会效益。

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 4 500 t/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.
