Feb 26, 2019 · A sequence of how these controls work is as follows: You start the boiler and allow the pressure to build. Once the pressure reaches your set point, 10 Psig, the burner shuts off. The burner stays off until the pressure inside the boiler drops to the differential (2 psi) setting minus the setpoint.

Steam Temperature Control | Control Notes

Steam flow from the boiler is controlled by the downstream process (e.g. a turbine). A sudden increase or decrease in steam flow changes the pressure in the steam drum and boiler circuit. The change in pressure will cause a change in both the boiling point and density of the water and steam.
