The pressure inside the boiler is further reduced, and a proportion of the boiler water will flash to steam. The flashing of the boiler water, plus the increased heat input as the burners turn up to maximum, means that the boiler 'water' will contain even more steam bubbles, and its density will be further reduced.

Pressure. Residential steam boilers operate under very low-pressure conditions. However, a large volume of low-pressure steam can be a danger. For this reason, there are pressure controls on the boiler. Normally set at 2 P.S.I., the pressure control will shut down the system if too much pressure is sensed by the pressure control.

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.
