Abstract
The present invention provides a thermal cracking tube having the effect of agitating a fluid in the tube and capable of preventing overheating due to the generation of laminar flow, wherein the thermal cracking tube 10 has an agitating element 20 formed on and projecting inwardly from an inner surface of the tube, wherein the fluid agitating element comprises a fin 21 extending along the inner surface of the tube and bumps 24 provided on a region near the fin and projecting inwardly from the inner surface of the tube, wherein the region near the fin includes an upstream side and/or a downstream side of the fin in the direction of the fluid flowing through the tube.
Claims10
A thermal cracking tube having one or more fluid agitating elements formed on and projecting inwardly from an inner surface of the tube,
- the one or more fluid agitating elements comprising
- a fin extending along the inner surface of the tube, and
- bumps provided on a region near the fin and projecting inwardly from the inner surface of the tube, wherein
- the fin comprises a plurality of fins formed on the inner surface of the tube at an interval of I, and
- the bumps are provided on the region at least up to I/2 of the upstream side and/or I/2 of the downstream side of the fin.
A thermal cracking tube having one or more fluid agitating elements formed on and projecting inwardly from an inner surface of the tube,
- the one or more fluid agitating elements comprising
- a fin extending along the inner surface of the tube, and
- bumps provided on a region near the fin and projecting inwardly from the inner surface of the tube, wherein
- an area S excluding the fin on the tube inner surface is at least twice larger than an area S′ occupied by the bumps on the tube inner surface.
