    • 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.
    • 公开了一种管状火焰燃烧器,燃烧方法和燃烧控制器。 这里,管状火焰燃烧器包括:一端敞开的管状燃烧室; 燃料喷射喷嘴和含氧气体喷嘴。 相应的喷嘴孔形成在燃烧室的内表面中,使得每个喷射方向在燃烧室的内周壁的切线方向附近。 并且点火装置设置在从燃烧室的管轴(r:燃烧室的半径)的r / 2的位置。 可以调节燃烧室的长度,管状火焰燃烧器是由多个管状火焰燃烧器形成的多级燃烧器,内管和外管之间的间隙用作气体流路。 公开了一种用于管状火焰燃烧器的燃烧控制方法,其中控制切换阀的开/关使得来自每个喷嘴的喷射速度保持在对应于燃烧负荷的预定范围内。
