摘要： The present invention relates to the field of fluid heat transfer, and discloses a heat transfer enhancement pipe as well as a cracking furnace and an atmospheric and vacuum heating furnace including the same. The heat transfer enhancement pipe (1) includes a pipe body (10) of tubular shape having an inlet (100) for entering of a fluid and an outlet (101) for said fluid to flow out; internal wall of the pipe body (10) is provided with a fin (11) protruding towards interior of the pipe body (10), the fin (11) spirally extends in an axial direction of the pipe body (10), wherein a height of the fin (11) gradually increases from one end in at least a part extension of the fin. The heat transfer enhancement pipe can reduce thermal stress of itself, thereby increasing service life of the heat transfer enhancement pipe.

摘要： A heat transfer tube includes a twisted baffle arranged in an inner wall of the tube. The twisted baffle extends spirally along an axial direction of the heat transfer tube. The twisted baffle is provided with a non-through gap extending along an axial direction of the heat transfer tube from an end to the other end of the twisted baffle. A cracking furnace uses the heat transfer tube. The heat transfer tube and cracking furnace have good heat transfer effects and small pressure loss.

摘要： The present disclosure relates to a heat transfer tube and a cracking furnace using the heat transfer tube. The heat transfer tube comprises a twisted baffle arranged in an inner wall of the tube, said twisted baffle extending spirally along an axial direction of the heat transfer tube. The twisted baffle defines a closed circle viewed from an end of the heat transfer tube. Along the trajectory of the circle a casing is arranged, which is fixedly connected to a radial inner end of the twisted baffle. The twisted baffle is provided with a plurality of holes. The heat transfer tube according to the present disclosure has a good heat transfer effect and small pressure loss.
