中速磨煤机侧机体刮板升级改造及效益分析

Upgrading and Benefit Analysis of Scraper of Side Body of Medium Speed Pulverizer

因中速磨煤机具有快速启动、结构紧凑、调节灵活、安全性高等优点,在火力发电厂中应用较为广泛。石子煤排放量不仅是影响磨煤机安全经济运行的重要参数之一,同时还是影响机组供电煤耗、热效率等经济指标。基于此,文章以中速磨煤机侧机体刮板装置升级改造为课题进行了深入分析,以期为同类改造工程提供经验和借鉴。

Due to the advantages of fast start,compact structure,flexible adjustment and high safety,medium speed coal mill is widely used in thermal power plant units.The emission of pebble coal is not only one of the important parameters affecting the safe and economic operation of coal mill,but also the economic indicators such as power supply coal consumption and thermal efficiency of unit.Based on this,this paper makes an in-depth analysis and Research on the upgrading and transformation of the scraper device of the side body of the medium speed coal mill,in order to provide experience and reference for similar transformation projects.
