Abstract
A cyclone combustion apparatus includes a combustion chamber having a substantially cylindrical wall, a substantially cylindrical exit throat at the rear end of the combustion chamber, means for supplying fuel into the combustion chamber at a front end thereof, means for supplying air into the combustion chamber and for forming a cyclonic flow pattern of hot gases for combustion within the chamber, and heat exchange means surrounding and extending throughout the axial length of the combustion chamber. The means for supplying air includes a plenum chamber having an air inlet and an annular air supply opening in communication with and coaxial with the combustion chamber. The annular air supply opening has spaced radial vanes tilted at a selected angle from the axis of the combustion chamber. The means for supplying fuel includes a fuel plenum chamber having a fuel inlet and a plurality of radially spaced fuel holes for supplying fuel in the annular air supply opening between the spaced radial vanes. Preferably, means are provided for supplying steam into the fuel plenum chamber for reducing the formation of NO.sub.x during combustion.
