Condensate Stall: Why Steam Heat Exchangers Need More Than a Bigger Trap

A steam-heated exchanger transfers heat as steam condenses on its heating surfaces. A modulating steam valve adjusts the heat input to maintain the required process outlet temperature. At lower demand, the valve can reduce steam-space pressure. For saturated steam, lower pressure also means lower saturation temperature.
