COAL HANDLING PLANT By wagon Tripler By means of two Coal is supplied The coal is drawn Into underground hopper By means of two Belts coal is transferred To the Conveyer Coal is supplied Through rail Track by own trains From nozzle coal Is discharged to furnace Coal is taken to Coal nozzle In wind box assembly Now coal is fed to Mills Where coal is Crushed in pulverized form Now coal is transferred to Crushing house and stored to bunkers

BOILER A boiler is a closed vessel in which water under pressure is converted into steam. A boiler is always designed to absorb maximum amount of heat released in process of combustion. This is transferred to the boiler by all the three modes of heat transfer i.e. conduction, convection and radiation.

TECHNICAL SPECIFICATION OF BOILER 1.TYPE Water tube ,pulverized fuel fired, single drum type, tangential firing system 2. MAKE BHEL 3. CAPACITY 680tonnes /hour(210MW) 4. PRESSURE 155 Kg./cm2 [G] 5.TEMPERATURE 540 degree

STEAM TURBINE Steam Turbine used is mainly of three types-: Turbine is a machine which converts the potential or kinetic energy of the steam into mechanical power by virtue of dynamic action of steam. Steam Turbine used is mainly of three types-: FIRST STAGE\HIGH PRESSURE TURBINE SECOND STAGE\INTERMEDIATE TURBINE THIRD STAGE\LOW PRESSURE TURBINE

PROCESS OF STEAM GENERATION

TURBO GENERATOR SPECIFICATIONS Manufactured by-:BHEL Rated Speed -:3000 RPM Power Output -:110 MW Power factor -:0.8 Rated voltage -:1000V Rated current -:7200A Cooling Element -:6

DEaRATOR Dearator is a device which is widely used for the removal of air and other gases from the feed water to steam generating boilers. in particular dissolved oxygen in Boiler feed waters will cause serious corrosion damage in steam system by attaching to the walls of metal piping and other metallic equipment and forming oxides.

Electro Static Precipitator To remove fly ash from flue gases electro static precipitator is used. They have collection efficiency of over 99.5%. The efficiency depends on various Factors such as velocity of flow, quantity of gas, resistivity of ash, voltage of fields, precipitators etc.

MAIN PARTS OF ESP : Electrostatic precipitator consists of following parts:- Casing Supply system Emitting electrodes Collecting electrodes Wrapping system Collecting basket

PRINCIPLE OF OPERATION Electrodes at high voltage create a corona effect (ionized atmosphere) surrounding them. This charges the passing particles. Once charged, particles are subject to a transverse electrostatic force that pulls them toward the collecting plates. Plates are periodically rapped (vibrated) to make the collected particles fall down into a receiver basket
