Operating Controls - National Board of Boiler and

Steam boilers require a device which senses steam pressure and cycles the burner or other source of heat in order to maintain a consistent, predetermined operating pressure. A second device is used to prevent the boiler from exceeding the maximum allowable working pressure (MAWP) indicated on the boiler nameplate.

How to set and adjust the boiler pressure control?

A question often asked is how to adjust the steam boiler pressure controls properly. While it seems like a straight forward thing, it is sometimes confusing because there are two different types of pressure controls for a boiler; Subtractive and Additive. The Subtractive version is the most common type of pressure control.
