Boiler feedwater valves: 6 reasons for leaking: oversizing

It is critical not to allow the HRSG to "dry out", which can cause severe thermal damage to the boiler tubes and the drums. To protect against this, the feedwater valves are sized for minimal pressure drop, allowing the maximum amount of water to flow to the drum. At this point, the normal feedwater inlet pressure to the high-pressure (h-p
