摘　　要：电石工业生产过程中会产生大量的副产品——电石渣,其主要成分为氢氧化钙。为了提高资源利用率以及降低电厂运行成本,可以使用电石渣作为炉内脱硫剂来替代传统方法中的石灰石。电石渣不仅可以实现废弃物的资源化利用,还能够有效降低脱硫成本,具有较好的经济性。针对200 MW循环流化床锅炉电石渣炉内脱硫性能进行了试验研究,结果表明电石渣具有良好的脱硫效果。此外,通过试验数据分析,对电石渣影响循环流化床锅炉效率的原因做了详细的分析。Calcium carbide production process will produce large amounts of by-products - carbide slag, its main composition is calcium hydroxide. In order to improve the utilization rate of resources and reduce the operation cost, using carbide slag as furnace desulfurization agent to replace the traditional method of limestone. Carbide slag can not only realize the resource utilization of the waste, on the other hand, can effectively reduce the cost of desulfurization, has better economy. According to the experimental study of 200MW CFB boiler carbide slag furnace desulfurization performance is analyzed, results show that the carbide slag has good desulfurization effect. In addition, through analyzing the test data, the reasons for carbide slag to CFB boiler efficiency were analyzed in detail.
