Abstract
On the basis of a macro flow resistance method and the Darcy Theory, a mathematical model is elaborated to characterize the flow resistance of a bag filter serving a coal-fired power plant. The development of the theoretical model is supported through acquisition of relevant data obtained by scanning the micro structure of the bag filter by means of an electron microscope. The influence of the running time and boiler load on the flow resistance and the impact of the flow resistance on the efficiency of the induced draft fan are analyzed by comparing the results of on-site operation tests. We show that the initial operation time and the table operation time are linearly related to the flow resistance of the bag filter; with the increase of boiler load, the flow resistance of the bag filter rises approximately as a quadratic function; with the rise of resistance, the power consumption of the induced draft fan increases while the efficiency of the induced draft fan decreases.
