Abstract
A tubular flame burner, a combustion method, and combustion controller, are disclosed. Here, the tubular flame burner comprises: a tubular combustion chamber whose h one end is open; fuel-spraying nozzles and oxygen-containing-gas spraying nozzles. The respective nozzle orifices are formed in the inner face of the combustion chamber so that each spraying direction is in a neighborhood of a tangential direction of the inner circumferential wall of the combustion chamber. And an ignition device is disposed at a position r/2 from the tube axis of the combustion chamber (r: the radius of the combustion chamber). The length of the combustion chamber can be adjusted, the tubular flame burner is a multi-stage burner formed of multiple tubular flame burners, and a gap between the inner tube and the outer tube serves as a gas-flow path. A combustion control method for the tubular flame burner is disclosed, wherein on/off of switching valves is controlled so that the spraying speed from each nozzle is maintained in a predetermined range corresponding to the combustion load.
