A KLAINA CYCLE APPLICATION FOR POWER-GENERATION

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.
