Water for the Boiler | Spirax Sarco

Water-tube boiler plant is much less tolerant of high TDS levels, and even less so as the pressure increases. This is due to a number of reasons, including: Water-tube boilers have a limited water surface area in the steam drum, relative to the evaporation rate.

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.

Is My Boiler Pressure Too High? | Hometree

Alternatively, if there is high boiler pressure, the system will be strained beyond normal capacity and could potentially fail. What is the correct pressure for a boiler? While not every boiler has the same pressure requirements, most central heating systems perform within the range of 1 to 2 bar, which is between 14 and 29 pounds per square inch (psi).
