Difference Between Low- and High-Pressure Boilers | …

Temperatures in high-pressure boilers will exceed 250 degrees F. Because of the elevated pressure at which these boilers operate, they need to be monitored to ensure safety at all times. High-pressure boiler operators must inspect switches, valves, safety devices and leaks on a regular basis.

High Pressure Boilers: Meaning, Types, Characteristics

These high pressure boilers have pressures above 140 bar and the temperature may be up to 540 – 610°C. High pressure boilers use both natural and forced circulations. Forced circulation is achieved with the help of centrifugal pumps. By using this forced circulation, because of high velocity of water scale formation in the tubes and boiler
