The 30-liter steam generator is a high-pressure boiler

An introduction to steam generation and distribution

Trevithick was the first to successfully use high-pressure steam (then known as "strong" steam). Until ca. 1800, the weakness of existing boilers coupled with the influence of James Watt had generally restricted steam boilers to very low pressures or "weak" steam.

Flash Steam | TLV - A Steam Specialist Company (North America)

Flash steam is a name given to the steam formed from hot condensate when the pressure is reduced. Flash steam is no different from normal steam, it is just a convenient name used to explain how the steam is formed. Normal or "live" steam is produced at a boiler, steam generator, or waste heat recovery generator – whereas flash steam

Boiler Safety | OSHA Safety Manuals

2017/3/15 · Boilers are gas-fired or electric closed vessels that heat water or other liquid to generate steam. The steam is superheated under pressure and used for power, heating or other industrial purposes. Though boilers are usually equipped with a pressure relief valve, if the boiler fails to contain the expansion pressure, the steam energy is released instantly.
