The quantity of
cooling water required to cool the steam in a thermal power plant layout is
significantly high and hence it is supplied from a natural water source like a
lake or a river. After passing through screens that remove particles that can
plug the condenser tubes in a thermal power plant layout, it is passed through
the condenser where the steam is condensed. The water is finally discharged
back into the water source after cooling. Cooling water circuit can also be a
closed system where the cooled water is sent through cooling towers for re-use
in the power plant. The cooling water circulation in the condenser of a thermal
power plant layout helps in maintaining a low pressure in the condenser all
throughout. All these circuits are integrated to form a thermal power plant layout that
generates electricity to meet our needs.
