Cargo Heating Coil - Steam Pressure
Steam supply pressure required for cargo heating coils to transfer design heat duty - correlates to saturation temperature.
Steam saturation T
85°C
Steam pressure (approx)
59.7bar(a)
Formula, assumptions, and limits
Antoine approximation of IAPWS-IF97. HFO target 65 °C → steam at 85 °C sat → 0.58 bar(a). Low-pressure saturated steam adequate for most cargo heating; superheated for sulphur/wax.
