Abstract
The influences of the emission of SO2 from the combustion of rice husk blended coal were analyzed by utilizing the experimental platform of Circulating Fluidized Bed(CFB).Based on different mass ratio of rice husk and lean coal,the mixed fuel was made and then combusted in the circulating fluidized bed.The data of temperature of the boiler and concentration of SO2 in the flue gas of the boiler were collected and analyzed.The results show that when the combustion temperature was constant,the emission of SO2 was decreased as the increasing of the mass ratio of rice husk in the mixed fuel.However,when the mass ratio of rice husk in the mixed fuel was a constant,the emissions of SO2 were increased as the increasing of combustion temperature.
