  • Boiler feedwater valves: 6 reasons for leaking: oversizing ...

    2021-8-17 · Designing for maximum conditions can lead to some of the operating and leakage problems with feedwater valves. The feedwater valves are normally sized to accommodate an operating condition that occurs when the safety valves open during a unit trip. It is critical not to allow the HRSG to “dry out”, which can cause severe thermal damage to the boiler tubes and the drums.

    Control of the boiler drum level is sophisticated, and even the best-tuned control systems cannot always prevent a low-water condition. The water level in a steam drum is actually a fairly unstable compressible mixture of water and steam bubbles that shrink and swell with pressure changes, firing rate changes, and when colder feedwater is added.

  • Water for the Boiler

    Water-tube boiler plant is much less tolerant of high TDS levels, and even less so as the pressure increases. This is due to a number of reasons, including: Water-tube boilers have a limited water surface area in the steam drum, relative to the evaporation rate. This results in very high steam release rates per unit of water area, and turbulence.
