【Abstract】 At present, SO 2 pollution control of coal combustion is an urgent task in the field of air pollution control in China. An experimental research was carried on the simulated pilot scale test facility of Circulating Fluidized Bed for Flue Gas Desulfurization (CFB FGD) whose diameter is 600?mm and nominal flow rate of the flue gas is 2?000?m 3/h in Thermal Engineering Research Institute of Southeast University. The Ca/S molar ratio and the reaction temperature have great influence on the efficiency of desulfurization, but the influences of the flow rate and SO 2 inlet concentration are not obvious. So the result indicates that CFB FGD technology is applicable for the variation of the boiler’s load and the coal used.更多还原
