Modeling On Desulfurization And Denitrification By Flue Gas Circulating Fluidized Bed And Mechanism Research

At the beginning of the paper the distribution of the velocity and concentration are obtained and a model about temperature is proposed. Then according to the analysis of the spraying water that can activate the sorbents a model about flue gas desulfurization by highly active absorbent is proposed. In the model, three factors are taken into account: gas-liquid reaction of slurry droplet, gas-solid reaction of dry circulating particles and surface coverage reaction of dry fresh particles. The higher accuracy of the model was exhibited with a max error of 5.5%. At last, denitrification mechanism of highly active sorbent is analyzed in detail, and a model about flue gas denitrification by highly active absorbent is achieved with a max error of 2%. Study works of the dissertation provide theoretical references for flue gas of desulfurization and denitrification that fitted the situation of our country.
