Abstract
Flue gases from two or more boilers are treated for reduction of their sulfur dioxide content by injecting as sorbent fine limestone or dolomite into one of the boilers, recovering a mixture of spent and calcined sorbent from the resulting flue gas, hydrating the resulting mixture to provide a dry slaked sorbent, and adding the dry slaked sorbent to sulfur-containing flue gas from a second boiler at a temperature of about 120.degree. to 230.degree.
