Abstract:
A heating unit and solid fuel feeder comprises a vertical furnace having a combustion chamber for burning solid fuel, a water jacket around the combustion chamber and an exhaust chamber at an upper outlet end of the combustion chamber. A plenum box is connected to the furnace and defines an interior space. Water circulation tubes extend from an upper end of the water jacket, through the plenum and into a water tank positioned on an opposite side of the plenum. Additional water tubes are connected between a lower end of the water tank and a lower end of the jacket. Water circulates as hot water rises in the jacket and falls in the water tank. A plurality of exhaust conduits which also extend in the plenum, are connected between the exhaust chamber and a smoke box. A stack is connected to the exhaust box. Air flowing or blown through the plenum picks up heat from the water pipes and exhaust conduit.
