In a steam generating boiler having a bottom wall supporting a char bed and sidewalls with ports through which air is admitted for combustion of combustible species in the char bed and emanating therefrom, combustion is improved by introducing an oxygen-containing gas into a lower central zone of the boiler, from at least one point remote from the sidewalls to thereby cause intimate mixing of the oxygen contained in the gas with the combustible species.

A method of improving combustion in a steam generating boiler having a bottom wall supporting a char bed and sidewalls with ports through which air is admitted for combustion species in the char bed and emanating therefrom, which comprises introducing an oxygen-containing gas into a lower central zone of the boiler, from at least one point remote from said sidewalls and from said char bed to thereby cause intimate mixing of the oxygen contained in said gas with said combustible species, said oxygen-containing gas being blown downwardly from an upper section of the boiler at a distance from said char bed sufficient to avoid oxidation of spent chemicals contained in said char bed.
