摘要：Aiming at the key technology in the retrofitting process of desulfurization ultra-low emission of large scale CFB boilers, the paper puts forward the measures for improving the efficiency of desulfurization in the boiler and its optimization measures. Aiming at the application of flue gas circulating fluidized bed desulphurization process in the retrofit of desulfurization with ultra-low emission, the arrangement of pre-electric precipitator, the optimum desulphurization distribution ratio outside the furnace and the relationship between desulfurization efficiency and cost in the furnace are put forward. The research can provide references for the newly built and retrofitted large-scale CFB unit with CFB flue gas desulfurization system.
