Evaluating the thermal efficiency and net power output of ORC for three wet fluids
Low-grade heat can be successfully recovered from waste energy sources for power production by an organic Rankine cycle (ORC). In this work, reheat ORC has been studied with three different wet organic fluids. The performance of R1270, R152a and Cyclopropane has been modelled in an ORC operated by...

| description |
Low-grade heat can be successfully recovered from waste energy sources for power production by an organic Rankine cycle (ORC). In this work, reheat ORC has been studied with three different wet organic fluids. The performance of R1270, R152a and Cyclopropane has been modelled in an ORC operated by a source of heat of 413.15K. The reheat ORC model contains economizer, evaporator, superheater, reheater, two turbine, pump and condensers. With variable turbine inlet temperature and reheat pressure, the net power output and thermal efficiency have been estimated. The results show that there exists an optimum temperature at the turbine inlet maximizing . The increase of reheat pressure gives only a marginal growth in the cycle efficiency, but it rises the with about 16.88 %, 16.26 % and 13.23 % for R1270, R152a and cyclopropane respectively.
