A multi-component (NH3/H2O) Kalina-type cycle that utilizes the exhaus
t from a gas turbine is investigated in this paper. The turbine-inlet
pressure of 5.96 x 10(6) N/m2 and temperature of 755.372 K were kept c
onstant, as well as the working fluid temperature at the condenser out
let (at 290 K). The NH3 mass fraction at the turbine inlet was varied
along with the separator temperature and the effects on the cycle effi
ciency were studied. The relationships between turbine-inlet flow and
the separator-inlet flow are shown in addition to the upper and lower
NH3 Mass-fraction bounds. The multi-component working-fluid cycle inve
stigated is 10-20% more efficient than a Rankine cycle with the same b
oundary conditions.
