Thermodynamic Analysis of Cascaded Organic Rankine Cycle for Optimizing Thermal Efficiency
Abstract: AbstractPower cycles converting medium temperature heat (~300°C) into electricity using working fluids like toluene, benzene etc. result in vacuum on condenser side operating near ambient temperatures. To overcome this, two stage cascaded power cycle is proposed with toluene in the top cycle and R- 245fa as a bottom cycle working fluid. In this scheme, condensation heat of toluene is used as a heat source for R- 245fa. A realistic analysis …
