Every steam system consists of the following major components: In the boiler, heat is added to liquid water to generate steam at a certain pressure. Boiler pressure is used to control the thermal capacity of the steam and to motivate the steam through the system. Steam exits the boiler through piping referred to as the steam header.Get Price
