锅炉磨煤机启停不投油的试验分析

Test analysis of pulverizer starting up or shutting down without burner firing oil

针对火电厂磨煤机启停时锅炉需投油助燃,增加发电成本的问题,华能大坝电厂对现有的磨煤机启停规程进行调整,对4台锅炉的磨煤机在设定条件下进行了启停不投油试验,确定了磨煤机启停时对应的燃烧器不投助燃油的锅炉运行条件。应用结果表明:实施磨煤机启停燃烧器不投油技术后,大坝电厂4台机组2014年至少节约燃油575 t,约合人民币413万多元,经济效益非常显著。

Aiming at the problem that when tile pulverizer starting up or shutting down,burner need add oil to support hearth combustion,increasing the generation cost of coal-fired plant,under designed condition, makes tile test of pulverizer starting up or shutting down without burner firing oil in Huaneng Ningxia Daba Power Plant,confirms the boiler running conditions of burner without the oil when the pulverizer starting up or shutting down. The application result shows that：after to implement the technology,4 units at least saving burning oil 575 ton,or about 4 130 000 Chinese yuan in Huaneng Ningxia Daba Power Plant,the economic benefit is evident.
