Boiler Post Purge When a boiler is turned off some heat remains in the mass of the boiler. If the flow through the boiler is stopped at the same time the boiler is shut off, the residual heat is lost. Therefore, after operation of the boiler the residual heat in the boiler should be purged to the system in order to decrease standby losses.

Gas pressure switches are not installed on every boiler and are typically used when the gas rating of the burner is greater than 2,500,000 Btuh. Safety-shutoff valves are the next components the gas train. It is most likely two redundant valves that are to limit the chance of gas leaking through into the boiler.

As we know, the reheat steam temperature adjustment method with the flue gas damper has the advantages of simple structure and convenient operation, which is used by many large‐scale power plant boilers. But both the opening degree of the flue gas damper and the change of steam temperature are nonlinear, and the effective range is narrow.
