Energy Performance of a Kalina Cycle based CHP plant driven by low-enthalpy geothermal sources

The low-enthalpy geothermal sources can be efficiently exploited for heat and power cogeneration by using the KCS-34 Kalina cycle systems. The maximum power for given heat source temperature and cooling temperature is obtained for a certain value of the ammonia-water solution concentration and turbi...
