Compounding of steam turbines
open-in-new
<p>In <a href="/facts/Steam_turbine/scacVXsB">steam turbine</a> design, compounding is a method of extracting steam energy in multiple stages rather than a single one. Each stage of a compounded steam turbine has its own set of <a href="/facts/Nozzle/9z8wqmEC">nozzles</a> and <a href="/facts/Turbines/gqosKCkI">rotors</a>. These are arranged in series, either keyed to the common shaft or fixed to the casing. The arrangement allows either the steam pressure or the jet velocity to be absorbed incrementally. </p>
