Abstract: Supercritical carbon dioxide (sCO2) power cycles could be a more efficient alternative to steam Rankine cycles for power generation from coal. Using existing labyrinth seal technology, shaft-end-seal leakage can result in ...

Abstract: Compared to traditional labyrinth seals, large-diameter (about 24 in or 609.6 mm) film-riding face seals are worth 0.55–0.65% points efficiency for utility-scale supercritical carbon dioxide (sCO2) turbines. Conventional ...
