摘要: 针对徐州华润电力有限公司2×1 000 MW超超临界燃煤机组启停及稳燃用油消耗量大的问题,采用将煤粉燃烧器改造为双强微油煤粉燃烧器,并设计相应辅助系统的做法,通过对比机组投用大油枪启动时的用油量,论证了双强微油点火系统的可靠性和经济效益的显著性。同时对双强微油点火系统运行中出现的微油燃烧器壁温超温、微油燃烧器点火不成功问题进行了分析,并提出优化方案。

Abstract: Regarding the existing problems of large oil consumption during boiler startup, shutdown and stable combustion processes in the two 1 000-MW units of Xuzhou China Resources Power, the coal burners are modified with double-strength less oil ignition technique and the associated auxiliary system is designed. By comparing the oil consumption of large oil guns during startup, the reliability and economic performance of the double-strength less oil igniting system are verified. In addition, the problems of less oil burner wall overheating and ignition failure during the burner operation are also analyzed, and the optimization measures are put forward.

Key words: boiler, double-strength less oil ignition, 1 000 MW, oil-saved
