Abstract
A method for the desulfurization of a calcium containing flue gas stream from a firing system such as a cement making plant wherein at least partially deacidified, hot raw cement meal is added to the flue gas at selected points to absorb the sulfur oxides to the calcium present in the gas. The preferred form of the invention comprises suspending the deacidified raw cement meal in the flue gas in the form of a cloud of airborne dust, and thereafter separating the dust from the flue gas after the sulfur oxides have been bonded to the calcium.
