A boiler with a cyclonic combustor includes a first chamber which is substantially uncooled and refractory lined, a second chamber in fluid communication with the first chamber, ducts for supplying air and fuel directly into the first chamber and for forming a cyclonic flow pattern of hot gases for combustion within the first and second chambers, an exit throat at the end of the second chamber and a heat exchanger surrounding the second chamber for keeping low combustion temperature in both chambers.

A boiler having a cyclonic combustor, comprising: A first chamber having a front end, a rear end and a substantially cylindrical longitudinally extending outer wall which is substantially uncooled and refractory lined; a second chamber having a front end, a rear end and a substantially cylindrical longitudinally extending outer wall, the rear end of the first chamber in fluid communication with and substantially longitudinally aligned with the front end of the second chamber; means for supplying air and fuel directly into the first chamber and for forming a cyclonic flow pattern of hot gases for combustion within the first chamber and the second chamber; a substantially cylindrical exit throat at the rear end of the second chamber and aligned concentrically therewith for exhausting hot gases from the second chamber, the exit throat having a diameter less than the inner diameter of the second chamber for inducing reverse flow zones within the first and second chambers; and heat exchange means surrounding the second chamber for substantially cooling the wall of the second chamber without substantially cooling the wall of the first chamber.
