The Application of Furnace Safety Supervisory System (FSSS) in the Oil-fired Utility Boiler

摘要

The boiler furnace explosion is a serious accident that must be avoided. There are more concerns about the loss of life, property, and production caused by boiler furnace explosions. In order to prevent furnace from exploding the furnace safety supervisory system's (FSSS) have been used in boiler safety control. This paper presents a FSSS's reference which is applied for two oil-fired boilers in Oriental (Shanghai) Petrochemical which produces CTA and PTA, a raw textile material. The boiler is a dual-fuel typeboiler, to which biomass and heavy oil can be fed simultaneously for combustion. This reference is implemented by Beijing Boiler Works. As the technical support, engineers from Tsinghua University are engaged in overall FSSS configuration, precommissioning. A series of problems are met during the test and modified by the vendors and contractors. It is a long distance to catch the level of the developed country's FSSS hardware such as flame scanner, on/off valve, pressure switch and so on. This paper presents a reference for FSSS in engineering field.
