ABSTRACT:
In this combustion process a fluid fuel such as pulverized coal mixed with primary air is injected along an axis and secondary air is injected along a helical path around the axis. Tertiary air is injected around the combustible fluid and the secondary air in substantially the same direction as the combustible fluid, in a substantial circumferentially continuous coaxial ring which is laterally confined downstream of the injection point.
