Title:
ENHANCED HEAT TRANSFER PIPE, AND PYROLYSIS FURNACE AND ATMOSPHERIC AND VACUUM HEATING FURNACE COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2019/080887
Kind Code:
A1
Abstract:
The present invention relates to the field of fluid heat transfer. Disclosed are an enhanced heat transfer pipe, and a pyrolysis furnace and an atmospheric and vacuum heating furnace comprising same. The enhanced heat transfer pipe (1) comprises a tubular pipe body (10) provided with an inlet (100) for a fluid to enter and an outlet (101) for the fluid to exit, an inner wall of the pipe body (10) being provided with ribs (11) which protrude towards the inside of the pipe body (10), the ribs (11) extending along the axial direction of the pipe body (10) in a spiral shape, an outer portion of the pipe body (10) being provided with at least one of a heat insulation layer (17) and a heat insulation piece (14). The thermal stress of the enhanced heat transfer pipe can be reduced, thereby increasing the service life of the enhanced heat transfer pipe.
