摘　　要：传统工业生产石灰的主要方式采用回转窑或立窑将石灰石煅烧而成,这两种生产方式都存在能源利用率低,烟气排放标准低等问题。本文探讨的新型生产模型采用高效燃烧共燃技术,配高效换热装置,将燃烧产生的热量用于发电,烟气经过节流式湿式脱硫除尘装置进行脱硫除尘,之后经过SCR脱硝装置进行烟气脱硝,经过多层处理后烟气通过烟囱达标排放。The main way of lime production in traditional industry is to calcine limestone in rotary kiln or shaft kiln.Both of them have the problems of low energy utilization and low emission standard of f lue gas.The new production model discussed in this paper adopts high-eff iciency combustion CO combustion technology,equipped with high-eff iciency heat exchange device,and the heat generated by combustion is used for power generation.Flue gas is desulfurized and dedusted by throttling wet desulfurization and dust removal device,and then f lue gas is denitrated by SCR denitration device.After multi-layer treatment,f lue gas is discharged through chimney.
