Abstraet--A multi-component (NH~/H20) Kalina-type cycle that utilizes the exhaust from a gas turbine is investigated in this paper. The turbine-inlet pressure of 5.96 × 106 N/m z and temperature of 755.372 K were kept constant, as welt as the working fluid temperature at the condenser outlet (at 290 K). The NH3 mass fraction at the turbine inlet was varied along with the separator temperature and the effects on the cycle efficiency 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 investigated is 10-20% more efficient than a Rankine cycle with the same boundary, conditions.
