Steam load of air heater battery estimator

Use to estimate the steam load required for an air heat battery

Air flow m3/s
Air on tmeperature °c
Air off tmeperature °c
Staurated steam pressure
Steam flow rate


  • Figures calculated are of a simple theoretical nature and other variables may need to be considered depending on application
  • Estimates based on saturated steam with 100% dryness. Steam pressure is the actual pressure into the coil itself, after any control valve.

Convert air flow rate from different units

m3/min = m3/s
m3/hr = m3/s
cfm = m3/s
