THERMAL POWER PLANT
1)BOILER/FURNACE:-
The boilertransfers energy
to the water by burningsome type of fuel.
The hot
water or steamtransfers its heat to aprocess.

THE BOILER SYSTEM COMPRISES OF
Feed water system:-Feed water system provides water to the
boiler
Steam system:- steam system collects and controls the steam
produced in the boiler
Fuel system:- The fuel system includes all equipment used to
provide fuel.
Two sources of feed water Condensate or condensed steam returned from the processes.
Makeup water (treated raw water) which must come from outsi
the boiler room and plant processes.

3 Deaerator
A deaerator is a device that is widely used for the removal of air and
other dissolved gases from the feed water to steam generating boilersIn particular, dissolved oxygen in boiler feedwaters will cause serious
It also combines with
any dissolved carbon
dioxide to form
carbonic acid.
Most deaerators are
designed to removeoxygen down to levels
of 7 ppb by
weight (0.0005 cm/L)
or less.

4 Heat Exchangers
Heat exchangers are equipment that transfers heat from one medium
to another.
Heat exchanger performance can deteriorate with time, off design
operations and other interferences such as fouling, scaling etc.
It is necessary to assess periodically the heat exchanger performancein order to maintain them at a high efficiency level.

5 Super Heater
A super heater is a device in a steam engine that heats the steam
generated by the boiler again, increasing its thermal energy.
Super heaters increase the efficiency of the steam engine, and were
widely adopted.
Super heaters were
applied to steam
locomotives
to most steam vehicles,
and to stationary steamengines including power
stations.

7 Economizers
Economizers, or in British English economisers, are mechanical devices
intended to reduce energy consumption, or to perform another usefulfunction like preheating a fluid.

8 Feed water heater
The feed water heating equipment then raises the temperature of the
water by utilizing extraction steam from various stages of the turbine.
Preheating the feed water reduces the irreversibility's involved in
steam generation
