<p>A method and apparatus (10) for combustion of a sulfurcontaining fuel which substantially reduces the amount of gaseous sulfur compounds which would otherwise be emitted. A source of oxygen, a sulfur-containing fuel, and an inorganic alkaline absorbent are reacted in a combustion zone (16) under controlled conditions of temperature, stoichiometry, and residence time whereby the inorganic alkaline absorbent reacts with the fuel sulfur to form a mixture of combustion products and desired solide sulfur compounds, the latter being readily removed utilizing conventional filtration equipment. In a preferred embodiment of the invention, the mixture of fuel and combustion products is passed into a nitrogenous compound destruction zone (20) wherein, under controlled conditions, the concentration of nitrogenous compounds present are reduced to a desired level.</p> |
