选煤技术在火电厂中的应用

Application of coal preparation technology in thermal power plants

火力发电厂采用电煤分选系统除去煤炭中的杂质,保证了煤炭质量,减少了对输煤、制粉、锅炉受热面等磨损,延长了设备使用寿命和检修周期;当分选系统投运时,可停运部分输煤系统设备以节约厂用电。分选系统投运以来,对火电厂节能环保方面取得了较好效果。

The power coal preparation system was utilized in thermal power plants to remove the impurities from coal, so as to ensure coal quality, reduce the wearing on coal conveyer, coal pulverizer and boiler heating surface, extend the life and service period of equipment. When the coal preparation system was put into operation, certain part of coal conveying equipment can be out of service to save more self-service power. In the light of such system, considerable progresses have been made in energy conservation and environment protection of thermal power plants.
