摘　　要：介绍了某电厂微油点火系统的原理和组成,对W形火焰锅炉使用微油点火系统点火用煤的选择进行了分析,对运行中出现的微油油枪点火失败、燃烧不好、微油燃烧器结焦及壁温超温等现象进行了分析并提出了相应的对策,指出为保证微油点火系统安全稳定运行,在系统安装、启动及停用过程中应注意的事项。An introduction is being presented to the principle and composition of tiny-oil ignition system in a certain power plant with W-flame boiler, together with an analysis on coal selection for the ignition system. Meanwhile, various phenomena occurring in operation of the boiler are analyzed, such as failed ignition of the tiny-oil gun, poor combustion, tiny-oil burner coking and overheated wall temperature, etc., to which corresponding countermeasures are proposed. Matters needing attention in the process of system installation, startup and shutdown are listed so as to ensure safe and stable operation of the tiny- ignition system.
