An improved method of reducing the amount of sulfur dioxide in combustion gases generated by the combustion of a sulfur-containing fuel in a combustion chamber. The improved method comprises introducing a sorbent composition capable of interacting with sulfur dioxide into a zone of the combustion chamber above the fuel and flame area, such that the sorbent composition is distributed throughout the combustion gases and interacts with sulfur dioxide to remove sulfur dioxide from the combustion gases in the form of a solid inorganic sulfate. The sorbent composition introduced into the combustion chamber comprises: (a) 100 parts by weight of a sorbent; and (b) about 0.25 parts to about 60 parts by weight of an enhancer, said enhancer comprising: (i) about 15% to about 75%, by weight of the enhancer, of a hydrated inorganic salt; (ii) about 25% to about 85%, by weight of the enhancer, of a clay; and (iii) 0% to about 10%, by weight of the enhancer, of a combustible liquid.

In a method of reducing the amount of sulfur dioxide in combustion gases generated by the combustion of a sulfur-containing fuel in a combustion chamber, including the steps of combusting the sulfur-containing fuel in the combustion chamber to generate combustion gases including sulfur dioxide; introducing a sorbent composition into the combustion chamber at a combustion zone above a fuel and flame area of the combustion chamber, said combustion zone having a sufficient temperature to calcine the sorbent composition; and calcining the sorbent composition in the combustion zone to allow interactions between the calcined sorbent composition and sulfur dioxide in the combustion gases to form a solid inorganic sulfate and decrease the amount of sulfur dioxide in the combustion gases; the improvement comprising introducing into the combustion chamber a sorbent composition comprising: (a) 100 parts by weight of a sorbent, and (b) about 0.25 parts to about 60 parts by weight of an enhancer, said enhancer comprising: (i) about 15% to about 75% by weight of a hydrated inorganic salt; (ii) about 25% to about 85% by weight of a clay; and (iii) 0% to about 10% by weight of a combustible liquid.
