Abstract
A method and equipment for desulfurizing exhaust gas from a combustor in which the exhaust gas containing SO.sub.2 from the combustor is brought into contact with SO.sub.2 absorbent to remove SO.sub.2 and is blown down out of the system; on the other hand, the SO.sub.2 absorbent absorbed SO.sub.2 is brought into contact with air to desorb SO.sub.2 and the air containing the desorbed SO.sub.2 is supplied to the combustor as air for combustion to burn to raise the SO.sub.2 concentration in the exhaust gas from the combustor; and the exhaust gas not undergone contact with the absorbent or a part of the air undergone contact with the SO.sub.2 absorbent are taken out of the system.
