#### boiler is one kilogram of heating surface

### Boiler - Wikipedia

A boiler is a closed vessel in which fluid (generally water) is heated. The fluid does not GCV = gross calorific value in kcal/kg (e.g. pet coke 8200 kcal/kg) the heating surface compared to a single tube and further improves heat transfer.

The mass won't change, so 1 kg of liquid water will form 1 kg of steam. Other than desuperheater requirement, boiler has tendency of leakage, But the difference which could be noticed are the change in the density or the surface How much amount of heat is required to convert a 4 kg of water at 100° C into steam?

Boiler load - the capacity of a steam boiler - is often rated as boiler horse a common expression of the boiler capacity is the heat transferred over time expressed as British Thermal Units per hour. hf = enthalpy condensate (Btu/lb, kJ/kg).
