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 partially preburned fuel into the combustion chamber at a front end thereof, means for supplying secondary 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 apparatus may also include a substantially cylindrical cooling chamber extending beyond the exit throat from the rear end of the combustion chamber and substantially longitudinally aligned with the combustion chamber. The combustion chamber, the exit throat and the annular secondary air supply opening are dimensioned and configured to effect a cyclonic flow pattern in the combustion chamber.

A cyclone combustion apparatus, comprising: a combustion chamber having a front end, a rear end and a substantially cylindrical wall having an inner surface; a substantially cylindrical exit throat at the rear end of the combustion chamber and aligned substantially concentrically therewith, for exhausting hot gases from the combustion chamber, the exit throat having a diameter less than the diameter of said inner surface; means for supplying partially preburned fuel into said combustion chamber from the front end thereof, said means for supplying partially preburned fuel including a precombustion chamber having a fuel inlet and a jet air supply inlet for admitting a desired mixture of fuel and air and an outlet connected to the front end of the combustion chamber for exhausting hot partially burned fuel gases into said combustion chamber; an annular primary air supply chamber having an annular outlet for discharging a primary air stream surrounding said partially burned fuel gases exhausted into said combustion chamber; means for supplying secondary air into said combustion chamber and for forming a cyclonic flow pattern of hot gases for combustion within said chamber, said air supply means including a plenum chamber fixed on the front end of the combustion chamber, said plenum chamber having an air inlet and an annular air supply opening in communication with and coaxial with the combustion chamber, said annular air supply opening having spaced radial vanes tilted at a selected angle from the axis of said combustion chamber to affect cyclonic air swirling in the combustion chamber; and heat exchange means surrounding and extending substantially throughout the axial length of the combustion chamber for cooling the wall in the combustion chamber.
