Abstract: The sulfur dioxide emissions of circulating fluidized bed boiler, in which the poor-grade coal with high sulfur and low heat value was burned and different desulfurization methods were adopted, were calculated and compared. The desulfurization combustion calculation of CFB boiler and sulfur dioxide emission of desulfurization outside the boiler were combined and analyzed. The calculations shows that when the process of inside boiler desulfurization combining with outside boiler desulfurization is adopted, the CFB boiler can burn poor-grade coal with high sulfur and can satisfy environment protection demands at the same time.
