西山煤电集团前山矿区为了提高下组高硫贫瘦煤开采比例,在各矿建设不同洗选工艺的选煤厂生产电精煤,这样可以调整产品结构、减少无效运输、保护环境、实现矿井可持续发展,同时提高供需双方的经济效益;某电厂的生产实践表明,燃烧电精煤发电,可少用煤、多发电,并可节约用电,节约助燃油,减少设备磨损,减轻环境污染。 In order to improve the proportion of high-sulfur and lean lean coal mined in the lower reaches, the Qianshan Mining Area of ​​Xishan Coal and Electricity Power Group Co., Ltd. produces clean coal at coal preparation plants with different washing processes at various mines so as to adjust the product structure, reduce inefficient transportation and protect the environment, Sustainable development, while improving the economic benefits of both supply and demand; a power plant’s production practice shows that coal burning coal power generation, less coal, more power generation, and can save electricity, save fuel, reduce equipment wear and reduce environmental pollution .
