AB - Kalina cycle system (KCS) operates at a heat source temperature up to 600ºC  with an improved heat recovery. The current work focuses on thermodynamic  processes development and assessment of a KCS configuration to augment the  power from a heat recovery of solar thermal collectors operating from 250ºC  to 600ºC. There are three pressure levels in current cycle i.e. high  pressure (HP), intermediate pressure (IP) and low pressure (LP). The  superheated vapor expands from HP to LP and the separator is located at IP.  The current work develops a new methodology for thermodynamic evaluation with  more flexibility compared to the reported method in literature. Separator  inlet condition (temperature and concentration), turbine inlet condition  (pressure, temperature and concentration) and solar radiation have been  identified as key parameters for the plant evaluation. The performance is  improving with an increase in separator temperature, turbine inlet pressure,  source temperature and solar radiation. But it is decreasing with an increase  in separator and turbine inlet concentrations. The cycle efficiency, plant  efficiency and specific power have been found as 23.5%, 7.5% and 675 kW at  0.3 separator concentration and 0.5 turbine concentration.
