(57) A method of operating a closed cycle power plant and also a closed cycle power plant
including a closed cycle power plant including heating means (A); a thermodynamic
prime mover (B); a cooling chamber in and,or round the prime mover (B); electric generating
means (C) drivingly coupled to the prime mover (B); a cooling chamber (11,12) in and
or round the generating means (C); condenser means (E); cooling means (F); a first
fluid line or circuit (1) extending from an outlet (2) from the cooling chamber of
the prime mover (B) through the heating means (A) and communicating with a high pressure
inlet (3) into the prime mover (B); a second fluid line or circuit (4) extending from
a low pressure outlet (5) from the prime mover (B) through the condenser means (E)
and communicating with an inlet (b) into the cooling chamber of the prime mover (B);
a third fluid line or circuit (7) branching off from the second fluid line or circuit
(4) downstream of the condenser means (E) and communicating with the cooling means
(F); and a fourth fluid line orcircuit (10) extending from the cooling means (F) to
the cooling chamber (11,12) of the generating means (C) and from there to the first
fluid line or circuit (1) in a position between the heating means (A) and the prime
mover (B); and means (13) operative to introduce fluid from the fourth fluid line
or circuit (10) into the first fluid line or circuit (1).
