2019-11-21 · Key Difference – Subcritical vs Supercritical Boiler. Boilers are closed vessels in which a fluid is heated, most of the times, it is water. Even though the name of this is a boiler, the fluid does not necessarily boil in this.

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.
