A method for reducing the emissions of sulfur dioxide and sulfur trioxide in exit gases resulting from the burning of sulfur bearing fuels, which includes the step of igniting alkaline earth metals simultaneously with the igniting of the fuel. The method provides for the burning of high sulfur content fuels while maintaining strict environmental emission requirements established for lower sulfur content fuels.

A method of reducing the sulfur content of exit gases exhausted from the burning chamber of an industrial boiler of a power generating plant and the like having an open flue and in which sulfur-bearing fuels are burned, said method comprising the steps of: continuously moving a stream of sulfur-bearing fuel into the burning chamber; adding to the stream of fuel prior to the fuel entering the burning chamber an aqueous solution of calcium nitrate so that the fuel and the calcium nitrate solution move together into the buring chamber; igniting the sulfur-bearing fuel and the calcium nitrate in the buring chamber in an open flame; and reducing the amount of sulfur available for conversion to sulfur oxide gases, by reaction between the calcium nitrate solution and reactive components in the sulfur-bearing fuel.
