The fast depletion of fossil fuel has increased the havoc and need of finding an alternative for
the existing fossil fuel based energy industry. As a result, many renewable energy sources
such as Solar, Wind, Geo Thermal, Bio mass, etc... are being looked in to. One of the major
sources of renewable energy is our sun. There are two methods of tapping the energy from
1. Solar Thermal
It involves using the sun’s heat directly in some processes or indirectly to produce electricity.
2. Photo Voltaic
It involves using the light to produce electricity using Photo Voltaic cells.
This report involves only the Solar Thermal part where the sun’s heat is indirectly used to
produce electricity. This report focuses mainly on a method known as Compact Linear
Fresnel Reflectors (CLFR). This method involves the focusing of sun’s energy to an over
head tube through mirrors arranged to form the shape similar to that of a Fresnel lens and
hence the name. Water runs in the over head tube, the focused energy from the sun, heats up
the over head tube and produces steam which in turn runs a steam turbine which in turn
This report focuses mainly the potential of using CLFR technology to be augmented in to
existing coal fired power plants in India. India has a solar reception of 5 Peta watt hours per
year with an average of 4 – 7 kW/m2 DNI. One of National Thermal Power Corporation’s
Coal fired thermal power station, Dadri Thermal Power Station, has been chosen for the
purpose of case study for this particular thesis. Since there is coal shortage at the power plant
location and the plant is not able to produce the peak load, our primary objective was to
achieve the production of peak load. The existing power cycle and the solar steam augmented
power cycles have been simulated using Thermoflow software and the results have been
