    • PROBLEM TO BE SOLVED: To highly efficiently transfer heat, and to reduce a pressure loss generated by a flow of fluid.SOLUTION: A heat transfer tube includes a tube 2 which forms an inner wall of a flow passage 6, and a plurality of protrusions 7-1 to 7-n which are intermittently arranged spirally along the inner wall. In such a heat transfer tube 1, when fluid flowing in the flow passage 6 is a mixture obtained by mixing a gas and liquid, a swirl flow of the fluid is generated, the fluid is pressed against the inner wall by a centrifugal force of the swirl flow, and the inner wall can be entirely wet by the fluid. For this reason, such a heat transfer tube 1 can highly efficiently transfer heat to the fluid from the outside of the tube 2. Furthermore, since the plurality of protrusions 7-1 to 7-n are intermittently formed, the heat transfer tube 1 can reduce a pressure loss generated by a flow of the fluid flowing in the flow passage 6 compared with the other heat transfer tube in which protrusions are entirely formed at the spiral of the protrusion.
    • 要解决的问题:高效地传递热量并减少由流体流动产生的压力损失。传热管包括形成流动通道6的内壁的管2和多个突起 7-1至7-n沿着内壁螺旋地间歇地布置。 在这种传热管1中,当流动通道6中流动的流体是通过混合气体和液体获得的混合物时,产生流体的涡流,流体通过离心力被压在内壁上 漩涡流动,内壁可以完全被流体润湿。 因此,这样的传热管1能够高效地将热量从管2的外部传递给流体。此外,由于间歇地形成有多个突起7-1〜7-n,所以传热管1可以 与在突出部的螺旋状的突起整体形成的其他传热管相比,减少流路6内流动的流体的流动所产生的压力损失。

    • PROBLEM TO BE SOLVED: To provide a liquid spray burner and residual fuel removal method of the same having a low environmental load and capable of collecting residual liquid fuel. SOLUTION: A fuel removal line 37 connected to a fuel supply line 24 and a fuel removal valve 38 provided in the fuel removal line 37 are provided. By supplying gas to a tip side of a fuel nozzle 21 by a fan 27 during stop of combustion operation, pressure on the tip side of the fuel nozzle 21 is intensified, and the fuel removal valve 38 is opened. Thus, due to a difference between the pressure on the tip side of the fuel nozzle 21 and the pressure on a fuel discharge side of the fuel removal line 37, residual liquid fuel 39 inside the fuel nozzle 21 is removed from inside of the fuel nozzle 21 and discharged via the fuel removal line 37 and the fuel removal valve 38 (first fuel removal). Also after the first fuel removal, by supplying gas to the tip side of the fuel nozzle 21 by the fan 27, fuel vaporized inside the fuel nozzle 21 is sucked out from a fuel outflow hole 31 (second fuel removal).
