A Comparison of Flue Gas Desulfurization Processes Power plant desulfurization

A desulfurization process model was established by the double film theory of mass transfer The calculated mass transfer coefficients were in reasonable agreement with the experimental values and According to the desulfurization process period it can be divided into the coal power plant desulfurization desulfurization furnace and flue gas desulfurizationAccording to the temperature of desulfurization medium there are three ways for desulfurization mainly including wet dry and semi dryAt present flue gas desulfurization is the main method in the most coal fired power station In
