<p>A rotary boiler-combustor comprising a cylindrical housing rotatable about its axis and having a coaxial annular boiler extending circumferentially thereabout and rotatable with the housing as a unit. A stationary annular partition defines an annular combustion zone circumscribing the boiler, and a circumscribing stationary hood structure defines an exhaust chamber for combustion gases surrounding the stationary partition. Means are provided to rotationally drive the housing-boiler unit at a predetermined speed and provision is made for supplying combustion air and fuel to the combustion zone. A condenser for the pressure vapor generated in the boiler is mounted to rotate with said boiler, and a pre-heater for the boiler liquid condensate comprises a plurality of axially spaced coaxial annular fins having a plurality of heat exchange tubes extending therethrough and arranged circumferentially of the housing between the stationary partition and combustion gas exhaust chamber. The pre-heater rotates with the housing and operates to pump the combustion gases therethrough to the surrounding combustion gas exhaust chamber.</p> |
