OPERATION OF COALCOAL -FIRE -FIRE POWER PLANT
THERMAL POWER PLANT
There are basically three main units a thermal power plant: 1. Steam Generator or Boiler 2. Steam Turbine 3. Electric Generator
STEAM GENERATOR OR BOILER A
boiler or steam generator is a device u to create steam by applying heat energ water.
It
is a rectangular furnace about 50 ft (15 on a side and 130 ft (40 m) tall.
Its
walls are made of a web of high pres steel tubes about 2.3 inches (60 mm diameter.
STEAM GENERATOR OR BOILER Pulverized
coal is air-blown into the furn from fuel nozzles at the four corners an rapidly burns, forming a large fireball at center.
The
thermal radiation of the fireball heats water that circulates through the boiler tu near the boiler perimeter.

STEAM GENERATOR OR BOILER As
the water in the boiler circulates it abs heat and changes into steam at 700° 370°C.
It
is se arate arated d from from the water insid insidee a dru dru the top of the furnace.
The
saturated steam is introduced superheat pendant tubes.
Here
the steam is superheated to 1,000 °
STEAM TURBINE Steam
turbines are used to drive generators, which produce electricity.
The
turbines are driven by s generated in 'Boilers' or 'S Generators‘.
Energy
in the steam after it leaves boiler is converted into rotational ene as it passes through the turbine.
STEAM TURBINE The
turbine normally consists of th stages with each stage consisting o stationary blade (or nozzle) an rotating blade.
STEAM TURBINE

blades blad es co conv nver ertt th thee po pote te energy of the steam (temperature pressure) into kinetic energy (veloc and direct the flow onto the rota blades.
The
rotating blades convert the kin energy into forces, caused by press drop, which results in the rotation of turbine shaft.
STEAM TURBINE The
turbine shaft is connected generator, which produces the electr energy.
The
rotational speed is 3000 rpm.
TURBINE GENERATOR The
generators are used to con mech chaani nica call pow oweer, de deli live vere red d fro rom m shaft of the turbine, into elect power.
TURBINE GENERATOR The
mechanical energy from the turb is converted by means a
rotating magnetic field
produced by direct current in the copper win of the rotor or field,
which generates three-phase alternating cur and voltages in the copper winding of the s (armature).
The
stator winding is connected terminals, which are in turn connecte th t f d li f
