Abstract

The exhaust flue gas cooler in a 300MW oxy-coal fired boiler is taken as an object of study. The simulation model of the cooler was established by the method of lumped parameter. The change rule of the exhaust flue gas cooler parameters and the flue gas thermal physical property parameters were analyzed by the disturbance of the coal feeder speed. It is found that, the simulation model of exhaust flue gas cooler was established basing on the conservation laws of mass and energy. The simulation experiment results show that the change rules of main operational parameters and the flue gas thermal physical property parameters in the exhaust flue gas cooler can be reasonably presented by the model with the speed disturbance of coal feeder, which can be the reference for the design and the operation control of the flue gas coolers.
