How To Properly Adjust Boiler Steam Pressure Controller …

It is impractical to reduce the steam temperature to its saturated value, as the control system is unable to differentiate between saturated steam and wet steam at the same temperature. Because of this, the temperature is always controlled at a value higher than the relevant saturation temperature, usually at 5°C to 10°C above saturation.
