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： The invention relates to the field of cracking, and discloses a cracking reaction device, a method and use of producing olefins by cracking. The cracking reaction device of the present application includes a preheating section, a lightening section, a reduced-pressure gasification section and a cracking section that are connected sequentially. The method for producing olefins by cracking in the present application includes pressurizing a cracking feedstock and water; subjecting the pressurized cracking feedstock and water to a first heating; subjecting the first heated cracking feedstock and water to a second heating and lightening the cracking feedstock in the presence of water to obtain a lightened mixture; gasifying the lightened mixture under a reduced pressure and subjected to a third heating to obtain a third heated mixture; and cracking the third heated mixture at a cracking temperature in the presence of steam to obtain a cracked product containing olefins.
