Thermal Power plant works on the basis of Rankine Cycle (Steam Turbine Power Plant). The Rankine cycle as a system converts thermal energy of the steam into mechanical energy by means of a turbine rotation, which runs the generator to produce electrical energy.
Hence, the correct option is (C).
&Key Points:-
In a simple Rankine
cycle, steam is used as the working fluid, generated from saturated liquid
water (feed-water). This saturated steam flows through the turbine, where its
internal energy is converted into mechanical work to run an electricity
generating system.
All the
energy from steam cannot be utilized for running the generating system because
of losses due to friction, viscosity, bend-on-blade etc. Most of the heat
energy is rejected in the steam condenser. The feed water brings the condensed
water back to the boiler.
Brayton Cycle
is used in gas turbine power plant.
