Continuous Flow Heating — Condensate Load

The steam demand and trap capacity for heating a liquid flowing continuously through an exchanger.

Unit system

Inputs

Liquid flow

Specific heat of the liquid

Water 4186 J/(kg·K). Oil ≈1900, milk ≈3900, syrup ≈3400.Inlet temperature

Outlet temperature

Steam pressure (absolute)

Heat transfer efficiency

Safety factor

Steam demand = condensate load

2,417kg/h

Heat duty

1,432kW

Trap capacity (with safety factor)	3,625 kg/h
Steam temperature	143.6 °C
Latent heat	2,133 kJ/kg
Steam-to-outlet approach	63.61 K
Assessment	The temperature difference is workable; size the trap on the full-load capacity.

Only the LATENT heat of the steam is used. Condensate leaves at saturation; sub-cooling reduces the steam demand slightly.
Specific heat is taken as constant; over a wide range enter a mean value.
