High Pressure Boilers: Features and Advantages ~ ME Mechanical

A boiler is called a high-pressure boiler when it operates with a steam pressure above 80 bars. The high-pressure boilers are widely used for power generation in thermal power plants. In a high-pressure boiler, if the feed-water pressure increases, the saturation temperature of water rises and the latent heat of vaporization decreases.

Boiler Pressure Too High? 4 Fixes to Reduce Boiler Pressure

What Boiler Pressure Is "Too High"? Anything above 1.5 bar isn't ideal. 2 bar starts to become more serious and when most boilers hit 3 bar, they're in the red zone on the pressure gauge. So, the unit is likely to lock out and display a fault code. If this happens, I'd suggest speaking to a Gas Safe boiler engineer. Why Boiler
