The influence and prevention measure for the integration of IDF and BF in the boiler furnace and flue gas system

Abstract

Abstract:

With the prevalence of ultralow emission reformon flue gas, the integration of induced draft fan (IDF) and boost fan (BF) in the power plant is commonly applied in power stations. Based on the DL/T 5240—2010 Technical Code for Design and Calculation of Combustion System of Fossilfried Power Plant, a safety assessment on the boiler furnace and flue gas system of a 330MW unit was carried out. It was found that the possibility of internal explosion of boiler furnace and flue gas system caused by highpressure largeflow IDF was increased. It is suggested that by optimizing the design and selection of the IDF, optimizing the resistance of the flue gas system and improving the pressure protection system of thermal control, the probability of internal explosion of boiler furnace and flue gas system could be reduced.
