2016-7-4 · Superheated steam is steam at a temperature higher than the saturation temperature corresponding to pressure. For example, a boiler may operate at 415 psig (pounds per square inch gauge). The corresponding saturation temperature for this pressure is 483°F, and this will be the temperature of the water in the boiler and the steam in the drum.

Benson Boiler - Construction, Working Principle and

Benson Boiler is a high pressure, drum less, supercritical, water tube steam boiler with forced circulation. This boiler was invented in the year 1922 by Mark Benson. This boiler is a super critical boiler in which the feed water is compressed to a supercritical pressure and this prevents the formation of bubbles in the water tube surface.

Why you can't use high-pressure steam boilers on low

That causes water hammer, which can break just about anything standing in its way. It will also lead to wet steam, which is not of much use when you're trying to heat something. This is why you can't run a high-pressure boiler on low-pressure settings. The boiler manufacturer told the contractor about this when the contractor called to ask.
