Abstract: The Aim of this work was to find out how feasible it is techno-economically to connect
low/high temperature solar collectors with ORC generators for power generation. The
prediction of the performance of energy systems that recover power from low/high grade
heat is one of the most important requirements for reducing the investment cost and
optimizing system efficiency.
A software package (AxCYCLE Heat Balance Calculation), simulating ORC system
performance was therefore used for this purpose. For low temperature heat input the ORC
generators were assumed to be connected to a CPC field with evacuated tubes to provide
the required heat input to run the cycle. While for the case of high temperature heat input
Arun dish was assumed to be connected to an ORC for power generation. This heat input
was then used to carry out the simulation in the software package to determine the
working cycle efficiency and other cycle parameters. Commercial applications were
found out for the technology and the market where it could be best used. Cost analysis
was done for the same to find out the return period and how system costs could be
reduced by using indigenous as well as imported parts for the system.
Keywords: ORC, CPC, Arun dish, CraftEngine, Turboden, AxCycle.
