摘要
针对神华宁夏煤业集团有限责任公司煤化工生产的实际情况,分析了德士古、四喷嘴对置式、GSP3种煤气化炉细渣的钙、镁、铝、铁等氧化物组分含量及烧失量,结合粉煤灰综合利用国家标准及行业标准,对煤气化细渣用于水泥、混凝土等建材及道路路基掺混料等进行了可行性分析,提出了煤气化细渣掺烧利用和分选利用的建议。
The components of calcium, magnesium, aluminum, iron oxides and LOI of the fine slag from three different kinds of coal gasifiers were analyzed based on the actual production practice of the Shenhua Ningxia Coal Industry Group Co., Ltd. Feasibility study was made on the fine slag from coal gasification units to he used for making building materials, e.g. cement, concrete or as the blending materials for constructing road beds of highways, taking into account the national standard and industrial standard. The paper proposed that the fine slag from coal gasification units could be blended into the boiler feed coal as a means of its comprehensive utilization.
