Abstract

The organic Rankine cycle (ORC), which
generates electric energy using low temperature heat sources, is a promising
technology in energy production sector. The ORC, which uses an organic fluid
with its lower boiling point and higher vapor pressure
than water-steam as a working fluid. The thermal
efficiency of an ORC showes the performance of system, depends on system
compenents, working fluid and operating conditions. This paper presents an
thermodynamics examination of basic ORC and regenerative ORC for waste heat
recovery applications using dry organic fluids. R113, R114, R227ea, R245fa and
R600a with the boiling points from -16 oC to 48 oC are
selected in the analyses. The relationships between the ORC's performance
parameters for basic and regenerative technologies and the properties of
working fluids are evaluated based on various turbine inlet pressure values.
Results show that regenerative ORC has higher thermal efficiency compared with
basic ORC. Also, the thermal efficiency increases with the increment of the
turbine inlet pressure for both
basic ORC and regenerative ORC.
