Abstract: In the present paper, parametric optimisation, energy and exergy analyses of KC were performed together with economic and environmental analyses. After parametric, energy and exergy analyses of KC, maximum net power production, thermal efficiency and exergy efficiency of KC were calculated as 389.44 kW, 33.86% and 68.96% at 430°C turbine inlet temperature and 95% ammonia mass fraction. At this working condition, where the best performance obtained from KC, maximum CO₂ emission reduction, investment cost, unit investment price, payback period and unit cost of generated electricity were found as 257.13 kg-CO₂/h, 501,115 $, 1,243 $ /kW, 2.93 years and 0.0265 $ /kW.

Keywords: reheat furnace; Kalina cycle; waste heat recovery; economic analyses; environmental analyses; energy; exergy.
