Abstract

See full text

The pre-mix burner assembly includes a jet pump comprising a combustion air tube, a flue gas inlet, and a suction chamber. The combustion air tube has an inlet and a tapered nozzle, and it is connected to a combustion gas fan. The flue gas inlet is connected to the suction chamber and the furnace chamber or other flue gas source. The suction chamber surrounds the combustion air tube, and it has a jet pump nozzle with a discharge. The combustion air exiting the combustion air nozzle creates a negative pressure in the suction chamber and draws flue gas into the suction chamber. There is a burner housing positioned downstream of the jet pump discharge. There is a fuel gas inlet connected to a mixing tube in the burner housing, and a burner block connected to the outlet of the burner housing.
