摘要:
通过磨煤机系统调整试验,本文探讨了煤粉细度和能耗与分离器开度、加载力、出力、风量等变化关系,优化了磨煤机运行参数,改善了磨煤机风煤比均衡性及煤粉细度;通过变一次风量、变氧量及变燃烧器配风等试验,研究了锅炉运行各参数对锅炉效率的影响。根据试验结果对机组运行参数进行了优化调整,解决了机组运行过程中存在的飞灰可燃物含量高、排烟温度高等问题,改善了机组运行的经济性和安全性。

Abstract: Through the adjustment experiment of the coal mill system, we investigated the changes of the coal fineness and the energy consumption with the opening degree of the splitter, the loading force, the output and the air volume and then optimized the operating parameters of the coal mill, improved the equilibrium of the coal-air ratios and the coal fineness. Through the experiments of the change on the primary air, the oxygen and the style of the burner with air, we researched the effects of the operating parameters of the boiler on the boiler efficiency. According to the experiment results, we adjusted the operating parameters of the generating unit, solved the high carbon of the fly ash and the high exhaust gas temperature of the generating unit and improved the eco- nomy and security of the generating unit.
