摘　　要：芜湖发电有限责任公司2×660MW发电机组配备1台35t/h的燃油锅炉作为启动备用,但实际投用过程中,故障频发,点火成功率低,燃爆风险大,点燃后燃烧不稳定,极易熄火,而且由于燃烧不充分,浓烟滚滚,严重不符合环保部门管理要求。为解决以上问题,恢复正常启动备用功能,对其开展了优化升级改造。本文将从技术革新和控制优化等方面,阐述解决以上问题的具体措施和收益效果,为存在类似故障问题的燃油锅炉或通用锅炉的燃油系统优化升级提供参考。The 2×660MW generator set of Wuhu Power Generation Co.,Ltd.is equipped with a 35t/h oil-fired boiler as a start-up backup,but during the actual commissioning process,failures frequently occur,the ignition success rate is low,the risk of explosion is high,and the combustion is not stable after ignition,and is easy to flame out.And due to insufficient combustion,thick smoke billows,which seriously does not meet the management requirements of the environmental protection department.In order to solve the above problems and restore the normal start-up backup function,optimization and upgrading is carried out.From the aspects of technological innovation and control optimization,this paper will describe the specific measures and benefits to solve the above problems,and provide a reference for the optimization and upgrading of oil-fired boilers or general-purpose boilers with similar failure problems.

关 键 词：启动锅炉 燃烧不稳 燃油优化 可靠性
