| 摘要 |
The present invention relates to a heat exchange tube for a heat recovery steam generator, which consists of heat exchange fins, and a manufacturing apparatus thereof. The heat exchange tube allows the fins to be alternately inclined and adjacent to the fins in the adjacent rows, accurately performs a fin forming work regardless of the welding speed of the fins, and allows the fins to be used in common regardless of the length and width of the fins. For the present invention, the manufacturing apparatus of the heat exchange tube for a heat recovery steam generator includes: an inclined fin forming part which alternately inclines each fin of the heat exchange fins in the winding direction of the heat exchange fins and deforms the fins among the heat exchange fins located opposite to each other to be adjacent to each other during a work for winding the heat transfer fins around a tube body in a spiral shape and welding the heat transfer fins. The heat exchange tube manufactured by the manufacturing apparatus is composed of planar fins and inclined fins inclined toward the planar fins. |
