Oct 26, 2019· Recognize that the pressure is high if the gauge reads higher than 3 bars or 45 psi. The pressure limits and ranges are different for each boiler depending on its size and type, but generally speaking, a pressure gauge should read between 1-2 bars or 15-30 psi. The pressure may be lower if it is warm out, or higher if it is cold out.

Modern power generation plants generally use high pressure boilers. 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 …

Another source of turbine deposition is the vaporization of salts present in boiler water. With the exception of silica, vaporization of boiler water salts is usually not significant at pressures below 2400 psig. Silica can vaporize into the steam at operating pressures as low as 400 psig. This has caused deposition problems in numerous turbines.
