What Causes Low Boiler Pressure? - Boiler Guide

If your boiler has low pressure then it is likely that you have a water leak, or a bleeding radiator. Without a constant water pressure your boiler may not work at its optimum level. Low pressure can also be an indication that there is something wrong with your boiler system, so it's important to investigate what could be causing it.

Boiler Types and Classifications - Wiki - odesie by Tech

There are two general types of boilers: ''fire-tube'' and ''water-tube''. Boilers are classified as "high-pressure" or "low-pressure" and "steam boiler" or "hot water boiler.". Boilers that operate higher than 15 psig are called "high-pressure" boilers. A hot water boiler, strictly speaking, is not a boiler.

protective oxide films (passive films) under boiler conditions (low or zero oxygen levels). However, sulfite is not considered to be a good passivating agent because it does not passivate low pressure boilers, where sulfite is most often used. Passivation can be accomplished in high pressure boilers, but high dosages of sulfite are needed.
