Steam Heated Radiator

The heat capacity of a steam radiator can be expressed as

Hr = qs hs λr                           (1)

where

Hr = heat capacity of radiator (kW, Btu/h)

qs = condensate rate (kg/h, lb/h)

hs = latent heat steam (2675 kJ/kg, 970 Btu/lb)

λr = radiator temperature correction coefficient = 1 for room temperature 70oF (21oC) and steam temperature 215oF (100oC).

The radiator correction coefficient for other room and steam temperatures can be calculated

λr = [((215oF) - (70oF))/(ts - tr)]1.3                           (1b)

where

ts = average steam temperature (oF)

tr = room temperature (oF)

Steam Heated Convector

The heat capacity of a steam heated convector can be expressed as

Hc = qs hs λc                        (2)

where

Hc = heat capacity of convector (kW, Btu/h)

qs = condensate rate (kg/h, lb/h)

hs = latent heat steam (2675 kJ/kg, 970 Btu/lb)

λc = convector temperature correction coefficient = 1 for inlet temperature 65oF (18oC) and steam temperature 215oF (100oC).

The convector correction coefficient for other room and steam temperatures can be calculated

λ = [((215oF) - (65oF))/(ts - ti)]1.5                         (3)

where

ts = steam temperature (oF)

ti = inlet temperature (oF)
