ABSTRACT:
A method and apparatus for combustion of a sulfur-containing 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 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 solid 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 wherein, under controlled conditions, the concentration of nitrogenous compounds present are reduced to a desired level.
