Experiment Study On Desulfurization And Denitrification Technology By Flue Gas Circulating Fluidized Bed

The highly avtive absorbent with oxidization based on fly ash, lime and additive had been prepared. Highly active absorbent is used in CFB firstly, 90% desulfurization , 63% denitrification efficiency can be achieved under optimum operating conditions. Experimental results show that operation temperature and flue gas humidity are the important parameter affecting the desulfurization and denitrification efficiency. Preparation, desulfurization and denitrification mechanism of highly active sorbent is analyzed in detail.The change of microcosmic structure of active absorbent is achieved according to the SEM pictures. Operation results show that the installation is reliable and simple with low invest and running cost, study works of the dissertation provide theoretical references and practice experiences for flue gas of desulfurization and denitrification that fitted the situation of our country.Huang Jianjun(EnvironmentaI Engineering) Directed by prof.
