Abstract
A method and apparatus for adjusting the flame exit velocity of a high velocity burner. The burner includes burner combustor chamber having a fluid accelerating nozzle and a burner combustor exhaust port. Fuel is delivered to the burner combustor through a fuel inlet. An ignitor is provided to initiate combustion of the fuel which is mixed with air from an air inlet. An adjusting device is provided to vary the flame exit area of the burner. The adjusting device includes an adjusting rod connected to an extension rod which preferably extends through the burner ignition chamber to the burner combustion exit port. For example, a tapered plug is attached to the end of the extension rod. The tapered plug is tapered in a direction decreasing toward the burner combustion exit port and can include fins attached around a periphery of the plug.
