DRising energy demand due to industrial development, population growth, is pushing the mankind for utilizing more and more conventional energy sources such as coal, oil and gas. There is a need to minimize the use of such types of resources because, it contributes to the global warming, pollution and climate change. Use of alternative sources of energy such as solar, hydro, wind, tidal, geothermal, biofuel, and nuclear are preferable and are promising for the modern world. Solar energy, which is abundantly available in Jorhat area, can be used for power generation using Organic Rankine Cycle (ORC) Technology, is the source of energy selected for this work. Use of solar energy can reduce the load on the conventional energy sources. Solar parabolic trough collector (PTC) system is employed as the evaporator of the solar organic Rankine cycle (SORC) system. Working fluid for the subcritical ORC is R245fa. Reciprocating piston type expander is used for the expansion of the working fluid. The 1 kW capacity alternator coupled to the expander shaft can convert the mechanical power into electricity. Two heat exchangers have been designed for the ORC prototype, one is an air cooled cross-flow heat exchanger for cooling the hot organic vapours and one shell and tube condenser (water cooled) for condensing the vapour into liquid state. Theoretical modelling of the prototype assembly is done using DWSIM and thermo-economic analysis has been carried out. Results indicate that the system can generate electricity in the range 439-763 W. The 1st law and 2nd law efficiencies of the cycle varies from 25.13 to 37.07% and 29.69 to 43.57% respectively. The payback period for the system is estimated to be around 17.27 years.
