CFD analysis – Radiant section tubes in a Hot Oil Furnace
Transheat scope
Study the fluid flow / velocity profile inside the radiant section tubes of a hot oil furnace to assess the possibility of hot spots in tubes (possible due to low velocity of fluid inside the tubes).
Installation in :India.
All design documents reviewed by : PDVSA, Venezuela and ASME AI.
Major design attributes
- Radiant tubes arranged as inverted U tubes connected to headers
- Design with partition in header for the multi pass arrangement.
- Tubes inside fluid is Therminol 66.
- Fluid flow rate = 700 m3/hr at 320oC
- Fluid flow geometry (inverse volume of solid geometry) of header and tube arrangement in ANSYS.
- Simulation is carried out without introducing energy to understand flow through tubes in normal conditions.
- Report in tabular and graph formats with flow profiles at different sections of the tubes.
