Abstract
A multi-component (NH3/H2O) Kalina type cycle that utilizes the exhaust from a gas turbine is investigated in this paper. The turbine inlet pressure, 5.96∗106 N/m2 (850 psig), and temperature, 755.372 K (900 F), were kept constant as well as the working fluid temperature at the condenser outlet, 290 K (62.3 F). 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 relationship between turbine inlet flow and separator inlet flow is shown in this paper in addition to the upper and lower NH3 mass fraction bounds. The multi-component working fluid cycle investigated is 10% to 20% more efficient than a Rankine cycle at the same border conditions.
