冶金石灰窑燃烧控制系统优化技术研究 摘 要 钢铁工业是我国国民经济重要基础和支柱性产业，石灰是钢铁冶金的重要原料，它作为高炉炼铁和转炉炼钢的熔剂，具有缩短冶炼时间、提高生铁质量和钢水纯净度等优点，可广泛应用于湿法烟气脱硫、酸性工业废水处理等环境保护领域、以及轻质碳酸钙、环氧氯丙烷、氧化铝烧结矿制备等冶金、化工生产过程。随着钢铁工业的迅猛发展，对冶金石灰提出了越来越高的要求。因此，开展冶金石灰窑生产过程质量控制理论及技术的研究，实现整个工艺过程综合优化和安全稳定运行，对于进一步稳定石灰煅烧品质，降低生产能耗，减少环境污染、保证钢铁冶炼质量，提高经济效益都具有重要意义。 本文以宝钢梅山钢铁公司套筒式石灰窑为对象，运用参数补偿原理设计了混合煤气流量在线检测方案，采用BP网络建立了石灰窑燃烧系统的优化控制模型，实现了石灰窑生产过程综合优化和稳定运行的效果。 关键词：冶金石灰窑；活性石灰；流量监测；燃烧控制 The optimization technology of metallurgical lime kiln combustion control system朗读显示对应的拉丁字符的拼音 字典 ABSTRACT Steel industry is an important basis for Chinas national economy and pillar industry. Lime is an important raw material of steel metallurgy. As a blast furnace and converter steelmaking flux, it can reduce refining time and improve the quality of pig iron and steel purity, etc. And it can be widely used in the field of environmental protection such as wet flue gas desulphurization and acidic industrial wastewater treatment field of environmental protection. It is also used in the metallurgical and chemical production processes such as calcium carbonate, epichlorohydrin, and preparation of alumina sintering. With the rapid development of steel industry, we need ??increasing demands on metallurgical lime. Therefore, we need to carry out a research on the control theory and technology of metallurgical lime kiln production process quality. Then the whole process can be integrated optimized and be work securely and steadily. This is of great significance on further stabilizing the calcite lime quality, reduce energy consumption, reduce environmental pollution, ensure the quality of the steel smelting and improve the economic efficiency. In this paper, The Baosteel Meishan Iron and Steel Company sleeve lime will be the targeted. I will use the principle of compensation with the parameter to design and implement the on-line detection program of mixed-gas flow. Then I established an optimal control model of lime kiln combustion system with the BP neura
