First of all, through the 理，研究不同脱硫渣在相关建材产品生产中优化利 research of their composition, structure and 用的理论和工艺控制参数，为其有效利用提供技术 physicochemical properties, to define their 依据。 performance characteristics, Prove the possible way of resources and utilization of them; 关键词： focused on discussing the factor in 干法脱硫渣 资源化 desulphurization slag of calcium sulfite type that impacted CaSO3 stability and oxidation; 前言 studied on the performance requirements and 随着国家加强对 SO2 排放的控制，燃煤 economic reasonableness of integrated activation technology at room temperature, 电厂开始采用烟气脱硫技术。目前，我国对 explored the laws and mechanism of internal 火力发电厂普通煤粉炉粉煤灰综合利用的 reaction based on the high-sulfur ash 研究己达到相当高的水平，开辟了广阔的利 cementitious materials of desulfurization 用途径。在一些地区，普通粉煤灰的综合利 residue, studed on the theory and process 用率已达到 80%以上。 control parameters of optimization utilization of different desulfurization slag in the relevant 作为脱硫技术之一的干法所产生的脱 production of building materials, to provide 硫渣在成分和性质上不同于脱硫前的粉煤 technical basis for its effective use. 灰。为了防止二次污染更好的利用新生资 Keyword: Dry desulfurizati
