will be replenished every day from the water source like river intake. This water
will be pumped from water tank to furnace through a pipe line. A water header
is used at the furnace to distribute water to various furnace equipment through
pipeline. The return water is collected in a trough and supplied back to the water
tank by gravity.
A cooling tower will be used to cool the return water and the cold water will
then be discharged in to the water tank.
Water from intake will first be treated to remove any impurity and to maintain
the desired pH level so as to avoid the scaling in the pipe line. The water storage
tank will be replenished with this treated water.
B. For CPP
The water system consists of the following sub-systems:
Raw Water System: The area where the power plant will be located, has a good
water potential both in the form of surface water and in the form of underground
water. Source of raw water for captive power plant will be Local River. A
detailed assessment regarding the availability of the water and quality had been
done which ensures the required water is available.
The power plant needs about 250 cum per day raw water for meeting its make
up water requirements.
Circulating Water System: The system caters to the cooling water requirement of
the condenser of the turbo generator, the auxiliaries of the turbogenerator, the
auxiliaries of the steam generators, the auxiliaries of CPP.A three cell, induced
draft cross low cooling tower with all the cell operating will supply the cooling
water for the CPP. The hot water returning from the condenser, the TG and
