摘　　要：为了实现煤电机组在低负荷下的稳定燃烧,降低启动过程中的燃油消耗,白山热电有限责任公司300 MW亚临界机组在原有微油点火的基础上进行了燃气点火系统改造,不同于常规的燃煤锅炉,该机组在炉膛安全监控系统(FSSS)逻辑设计上需考虑燃气的特殊性,详细介绍燃气点火FSSS在煤电机组上的设计和实现,涵盖炉膛吹扫、主燃料跳闸(MFT)、点火允许条件、燃气燃料跳闸(GFT)、燃气泄漏试验等内容,通过对原有FSSS逻辑的优化和改进,实现燃气点火系统在煤电机组上的安全稳定运行。In order to realize the stable combustion of burners under low-load,reducing theoil consumption during startup process,gas ignition system was added on Baishan power plant with a 300 MW subcritical unit.Different from the furnace safety monitoring system(FSSS)of conventional coal-burning boilers,this unit should consider the particularity of gas in the logical design of FSSS system.In this paper,the design and realization of the gas ignition FSSS system on the coal unit was introduced,covering furnace purging,main fuel trip,ignition allow conditions,gas fuel trip and the gas leak test.Based on the optimization and improvement of the original FSSS logics,safe opration of the gas ignition system on the coal unit has been relized.
