摘　　要：锅炉主燃料跳闸(Main Fuel Trip,MFT)是炉膛安全监控系统(Furnace Safeguard Supervisory System,FSSS)最重要的功能,当出现任何危及锅炉安全运行的危险工况时,立即切断所有进入炉膛的燃料,避免事故发生或限制事故进一步扩大,以确保锅炉设备的安全。本文通过对和利时公司火电项目锅炉MFT系统设计实施要点进行介绍和分析,希望对其他项目系统设计提供借鉴。Main fuel trip(MFT) is most important function of the furnace safeguard supervisory system(FSSS). When there is any dangerous condition endangering the safe operation of the boiler occurs, immediately cut off all the fuel entering the furnace to avoid accidents or limit their further expansion, so as to ensure the safety of the boiler equipment. This paper introduces and analyzes the key points of boiler MFT system design and implementation in Hollysys thermal power project, hoping to provide the reference for other engineering application.
