Abstract: The furnace safety supervision system (FSSS) is one of main protection devices of largescale coalfired units. The imperfection of design of FSSS poses a great threat to the unit safe operation. Combining with the features of main and auxiliary equipments and distributed control system of the combustion system of Weifang Power Generation Company Limited, the control logic design, the signal switchover and the design of the MFT hardware connecting circuit were optimized; so the safety and reliability of the boiler operation had been maximized.
