Abstract: In this paper, We designed Furnace Safeguard Supervisory System (FSSS) of gas-fired boiler, which includes the logic design of sweep control for ignition before and after shutdown, the logic design of sequence control for boiler ignition and blast-furnace gas, the logic design of Master Furl Trip(MFT) and Flame Detection. We achieved a gas-fired boiler furnace safeguard supervisory functions.

Abstract: Process industry control put very high demands on the reliability of DCS. Application of Redundancy Fault-tolerant Technology is one of the most effective way to improve the reliability of DCS. In this paper, we elaborated on the implementation scheme of DCS redundancy fault-tolerant in process industry control, which includes the configuration of DCS hardware system redundancy, the redundant fault-tolerant realization method of I/O module, etc.

Abstract: In this paper, we present an optimization control strategy for problems in conventional boilers send-guide-air automatic control system of power plant. We meet optimization of boiler send-guide-air automatic control scheme by means of improving air flow and oxygen content in flue gas measurement, revising control system structure, adopting fuzzy control algorithm, adding protection and other measures.
