Steam boiler technology is used for a wide range of applications. Low pressure steam boilers are limited to 15 psig design, and are commonly used for heating applications. High pressure boilers are most often used for process loads and capable of operating pressures ranging from 16 psig to more than 1,000 psig.

Decreasing the turbine exhaust pressure significantly increases the specific volume of exhausted steam, which requires huge blades in last rows of low-pressure stage of the steam turbine. In a typical wet steam turbines, the exhausted steam condenses in the condenser and it is at a pressure well below atmospheric (absolute pressure of 0.008 MPa, which corresponds to 41.5°C).

The pressure relief valve (PRV) releases water when the pressure in the system becomes too high. Sometimes, the PRV can have a leak or the valve may not close properly, this could gradually reduce your boiler's pressure. Alternatively, a filling loop (which is opened to allow water in when your boiler's pressure is too low) may have been
