# Steam Heating Air

Steam is often used to heat air. Steam condensing rate for air heating equipment can be calculated as

ms = q dt cp ρ / he                               (1)

where

ms = rate of condensation, steam consumption (kg/s)

q = volumetric air flow rate (m3/s)

dt = temperature difference in air flow (oC)

cp = specific heat of air (kJ/kg oC)

ρ = density air (kg/m3)

he = specific enthalpy of evaporating (condensation) steam (kJ/kg)

### Example - Heating Air with Steam

1 m3/s of air is heated from 10oC to 30oC with steam condensing at atmospheric pressure. The steam consumption can be calculated as

ms = (1 m3/s) ((30oC) - (10oC)) (1.0 kJ/kg oC) (1.204 kg/m3) / (2257 kJ/kg)

= 0.011 kg/s
