    Patent number: 4298333
    Abstract: A burner is connected to a fuel line and to an air supply line. A countercurrent recuperator is attached to the burner for providing heat exchange between the supply air and the exhaust gases. The recuperator has a frictional flow resistance to the exhaust gases and the supply air resulting in a pressure differential between entrance and exit of supply air, which is highly temperature dependent. This pressure differential is employed for self-controlling the relative supply air flow to the burner at different operating temperatures.
