Abstract

Mathematical model of a 300 MW boiler was created including furnace, super-heater, economizer, air pre-heater, ESP, and ID fan. Furnace implosion simulation was accomplished at 100% load during MFT and ID fan maloperation. The pressure changing process was summarized into three steps and flow character of each step was analyzed in detail. It is pointed out that furnace implosion is caused by many factors, such as air flowing-into, gas flowing-out, ID fan pressure, resistance of the gas duct, gas combustion, and so on. Such analysis is helpful for both theoretical and application purposes. Simulated values of steady combustion agree well with designed ones.
