Selection of low temperature thermal power cycles

In today?s world, we are facing the problem of fossil fuel depletion along with its cost continuously increasing. Also, it is getting difficult to live in a pollution free environment. Solar energy one most abundantly and freely available form energy. Out various ways harness solar energy, thermal efficient as compared photovoltaic technology. There cycles convert mechanical work, but Kalina cycle best candidates for high efficiency considerations. Therefore, authors have proposed novel having double separator arrangements increase amount ammonia vapors at inlet turbine, hence tried minimize pumping power by reducing fraction gas/vapors through it. Here, this paper compare ORC, Brayton cycle, low temperature heat extraction from parabolic trough collectors arc-circular plug slits. The effect different operating conditions, like number collectors, mass-flow rate fluids cycles, pressure difference turbine analyzed. these conditions on parameters net work done, lost condenser, installation per unit kW studied.
