Benson Boiler
A supercritical steam generator is a type of boiler that operates at supercritical pressure, frequently used in the production of electric power. In contrast to a subcritical boiler in which bubbles can form, a supercritical steam generator operates at pressures above the critical pressure. Therefore, liquid water immediately becomes indistinguishable from steam. Water passes below the critical point as it does work in a high pressure turbine and enters the generator's condenser, resulting in slightly less fuel use. The efficiency of power plants with supercritical steam generators is higher than with subcritical steam. Only with high pressure can higher temperature steam be converted more efficiently to mechanical energy in the turbine (as given by Carnot's theorem). Technically, the term "boiler" should not be used for a supercritical pressure steam generator as no "boiling" actually occurs in the device.

Mark Benson (engineer)
Mark Benson (born Mark Müller; Jun 19, 1888 – May 1965) was a Bohemian German engineer, best known as the inventor of a supercritical boiler. Benson was born in the Sudetenland, and his original name was Müller (he changed his name during World War I to hide his German origin). He emigrated to the United States, then returned to Europe to work for the English Electric Company in Rugby. For ''English Electric'' he designed a relatively small steam generator (3 tons/hr), but with—for the time—very high pressure (supercritical) and without any drum. In 1922 Benson was granted a patent for this type of boiler. In 1924, Siemens acquired the right to use Benson's patent, and in 1926–27 built the first large Benson boiler in Berlin Berlin ( , ) is the capital and largest city of Germany by both area and population. Its 3.7 million inhabitants make it the European Union's most populous city, according to population within city limits. One of Germany's sixteen constitue ...
