Heat Transfer Coefficients for Submerged Coils

Heat transfer coefficients for steam and hot water coils submerged in oil tanks

heating coil oil tanks

The heat transfer from steam coils with medium pressure, or hot water coils or pipes, submerged in oil or fat can be estimated with the values from the table below.

Type of Coil Heat Transfer Coefficient - natural convection
(W/m2 oC) (Btu/hr ft2 oF)
Steam to Light Oil 170 30
Steam to Heavy Oil 85 - 115 15 - 20
Steam to Fat 30 - 60 5 - 10
Hot Water to Oil 60 10
