... thermodynamics (i.e. "entspannend/expanding" and not "einspannend"), in line with Patrick's original interpretation. IMHO, it would be completely sufficient to say that "the steam is not expanded to perform any work through a thermodynamic cycle" -- or something along those lines.

Consider the definition of "thermodynamic cycle" at Wikipedia, for instance:
"A thermodynamic cycle consists of a series of thermodynamic processes transferring heat and work, while varying pressure, temperature, and other state variables, eventually returning a system to its initial state."

P.S. A shorter version would be "the steam is (not) thermodynamically expanded".

This is what I thought initially, but in another section of the document the following statement is made:-
"Allerdings wird der um die Dampfturbine vorbeigeleitete überschüssige Dampf nicht mehr arbeitspannend eingesetzt, wodurch der Wirkungsgrad der Anlage insgesamt verringert wird".


This appears to say that the surplus steam which bypasses the steam turbine is not used to perform work (by expansion), hence the efficiency of the plant is reduced.

is "entspannend" really = einspannend" = performing work? This is not my field, but simply from a linguistic view, I would think it could mean here saving work rather than performing work?!
