Heat Emission from Pipes Submerged in Oil or Fat
Heat emission from steam or water heating pipes submerged in oil or fat - forced and natural circulation
The viscosity of a fluid has considerable influence on the heat transfered from a submerged heating pipe. Be aware that the viscosity of a fluid is highly dependent on the temperature.
Heat emission from steam pipes submerged in oil baths are indicated below:
Application | Fluid | Heat Emission from coil surface | |
---|---|---|---|
(Btu/ft2 hr oF) | (W/m2 oC) | ||
Steam coil with medium steam pressure and natural convection of oil | Light Oils | 30 | 170 |
Heavy Oils | 15 - 20 | 85 - 115 | |
Fats | 5 - 10 | 30 - 60 | |
Steam coil with medium pressure and forced convection of oil | Light Oils | 100 | 570 |
Heavy Oils | 60 | 340 | |
Fats | 30 | 170 |
- Light oils - 220 SSU at 100 oF
- Heavy oils - 1100 SSU at 100 oF
- Fats - 3833 SSU at 100 oF
