SCHEMATIC ARRANGMENT OF STEAM POWER PLANT

Operation of Steam Power Plant Based on a clear Schematic:

Steam Power Plant basically operates on the Rankine cycle.

Schematic Arrangement of Steam Power Plant

• Coal is burnt in a Boiler,which converts water into steam.
• The Steam is expanded in a Turbine,which produces Mechanical Power driving the Generator coupled to the Turbine.
• The steam after expansion in Prime mover is usually condensed in a Condenser to be fed into the Boiler again.
• In practise,however,a large number of modifications and improvements have been made so as to effect economy and improve the Thermal Efficiency of the plant.
• The working of a modern Coal-fired Steam Power Plant ca be studied conveniently with the help of various Cycles.
• Main Constituents of a Steam Power Plant are.

        1.Boiler.

        2.Boiler Furnace

        3.Super heater and Re heater.

        4.Economiser and Air Preheater.

        5.Condenser.

        6.Prime Mover.

        7.Spray Ponds and Cooling Tower.

        8.Coal Handling Plant.

        9.Pulverising Plant.

        10.Draft System.

        11.Ash Handling Plant.

        12.Control Room.

        13.Switch Yard.
