Technical method for stably reducing coal consumption of cement clinker firing
The invention discloses a technical method for stably reducing coal consumption of cement clinker firing, which comprises the following steps of: high-silicon rock is replaced with medium-silicon rockand silica by adjusting a raw material proportioning scheme; industrial waste yellow phosphorus slag is blended as a mineralizing agent; fan configuration of a grate cooler is optimized, quenching isenhanced, and the heat recovery efficiency is improved; a grate plate structure and grate cooler control are optimized, and the heat recovery efficiency is improved; a pipe diameter of the inflatablebeam air supply pipeline is enlarged, the air volume is increased, and the heat recovery efficiency is improved; through system air leakage treatment, the oxygen content of an outlet of a preheater C1 is reduced; a novel flap valve is used for reducing internal air leakage, and a kiln tail sealing device is modified from cylinder sealing to graphite sealing to reduce external air leakage; a novelspreading box is used for improving the dispersity of materials in a decomposing furnace and a preheater, so that the heat exchange efficiency is improved; the position of the furnace coal burner isoptimized, and the combustion efficiency and the burn-off rate of pulverized coal are improved by using the furnace coal burner with a novel structure. By implementing the method, the production costof the cement clinker is greatly reduced, and remarkable economic benefits are obtained.
本发明公开了一种稳定降低水泥熟料烧成煤耗技术方法，通过调整生料配料方案，用中硅岩、硅石取代高硅岩；掺配工业废料黄磷渣做矿化剂；优化篦冷机风机配置，加强急冷和提高热回收效率；优化篦板结构和篦冷机控制，提高热回收效率；将充气梁供风管道管径扩大，增大风量，提高热回收效率；通过系统漏风治理，降低预热器C1出口氧含量；使用新型翻板阀降低内漏风，窑尾密封装置由气缸密封改造为石墨密封减少外漏风；使用新型撒料箱提高物料在分解炉、预热器的分散度，从而提高换热效率；优化炉煤燃烧器位置、使用新型结构的炉煤燃烧器，提高煤粉的燃烧效率和燃尽率。本发明的实施大幅度降低了水泥熟料的生产成本，取得了显著的经济效益。
