THERMAL POWER PLANT In
a Thermal Power Plant, one of coal, oil or natural gas is used to heat the boiler to convert the water into steam.
The
steam is used to turn a turbine, which is connected to a generator.
When
the turbine turns, electricity is generated and given as output by the generator, which goes to the high tension transformer then supplied to the consumers through high-voltage power lines.
THERMAL POWER PLANT
OPERATION OF COALCOAL-FIRED POWER PLANT
THERMAL POWER PLANT
There are basically three main units of 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 used to create steam by applying heat energy to water.
It
is a rectangular furnace about 50 ft (15 m) on a side and 130 ft (40 m) tall.
Its
walls are made of a web of high pressure steel tubes about 2.3 inches (60 mm) in diameter.
STEAM GENERATOR OR BOILER Pulverized
coal is air-blown into the furnace from fuel nozzles at the four corners and it rapidly burns, forming a large fireball at the center.
The
thermal radiation of the fireball heats the water that circulates through the boiler tubes near the boiler perimeter.
The
water circulation rate in the boiler is three to four times the throughput and is typically driven by pumps.
STEAM GENERATOR OR BOILER
Schematic Diagram of a Steam Generator or Boiler
STEAM GENERATOR OR BOILER As
the water in the boiler circulates it absorbs heat and changes into steam at 700°F or 370°C.
It
is separated from the water inside a drum at the top of the furnace.
The
saturated steam is introduced into superheat pendant tubes.
Here
the steam is superheated to 1,000 °F or 540 °C to prepare it for the turbine.
STEAM TURBINE Steam
turbines are used to drive the generators, which produce electricity.
The
turbines are driven by steam generated in 'Boilers' or 'Steam Generators‘.
Energy
in the steam after it leaves the boiler is converted into rotational energy as it passes through the turbine.
STEAM TURBINE The
turbine normally consists of three stages with each stage consisting of a stationary blade (or nozzle) and a rotating blade.
STEAM TURBINE Stationary
blades convert the potential energy of the steam (temperature and pressure) into kinetic energy (velocity) and direct the flow onto the rotating blades.
The
rotating blades convert the kinetic energy into forces, caused by pressure drop, which results in the rotation of the turbine shaft.
STEAM TURBINE The
turbine shaft is connected to a generator, which produces the electrical energy.
The
rotational speed is 3000 rpm.
TURBINE GENERATOR The
generators are used to convert mechanical power, delivered from the shaft of the turbine, into electrical power.
TURBINE GENERATOR The
mechanical energy from the turbine is converted by means a rotating
magnetic field
produced
by direct current in the copper winding of the rotor or field,
which
generates three-phase alternating currents and voltages in the copper winding of the stator (armature).
The
stator winding is connected to terminals, which are in turn connected to the power system for delivery of the output power to the system.
