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.

A steam boiler is a power generation device, used for generating steam by applying the heat energy to water. The pressure range of earlier boilers ranges from low pressure to medium pressure (7 kPa to 2000 kPa/ 1psi to 290 psi). The present boilers are more useful because it works with high pressure than old ones.

Unless a separate non-return valve is fitted in the steam connection, one of the two stop valves must incorporate a non-return facility. The objective of this section of the British Standard is to provide safe working conditions when the boiler is shut down for repair or inspection.

2011/1/17 · Our wood waste boiler outlet steam flow is quite variable depending on our users. The steam passes through a primary and secondary superheater. Between the primary and secondary superheaters we add feed water through a de-superheater station to control the secondary superheater outlet temperature.
