Steam Boilers | HVAC Heating Systems | Hydronics

The steam boiler must super-heat the water inside the water cavity to more than 212 degrees F. If the proper controls are not in the system a steam boiler can reach dangerous temperatures and possibly cause a fire. For a steam boiler to operate at the proper temperatures it needs some basic safety controls. Some of these are:

Superheated steam is steam at a temperature higher than its vaporization point at the absolute pressure where the temperature is measured.. Superheated steam can therefore cool (lose internal energy) by some amount, resulting in a lowering of its temperature without changing state (i.e., condensing) from a gas, to a mixture of saturated vapor and liquid.
