TRANSPORTATION OF COAL5 ways of Transportation.

• 1. Railways.• 2. Ropeways.• 3. Roadways.• 4. waterways.• 5. Airway.

Available only for TPS nearer to coal

mines

Have to build Runway near TPS which is very

costly.

waterway may not be possible till TPS and

Problem of recalling arises if coal dip in water

Best and Cheap facility at Doorstep

Fear of thief

WAGON TRIPLER IS A HEAVY MACHINE WHICH IS USE TO UNLOAD THE COAL FROM THE WAGON OF THE TRAIN AND DISCHARGE TO THE HOPPER FOR THE BETTER FULFILLMENT AND FOR NEXT OPERATION 10

2.WAGON TRIPLER

VIBRATING TYPE OR RECIPROCATING TYPE HOPPER ARE USED FOR COAL . AFTER COAL SENDING BY THE WAGON TRIPLER AND IT HELP TO MOVE FORWARD BY THE USE OF THE CONBVEYER BELT. FOR THE CRUSHING OF COAL IN THE CRUSHING HOUSE 11

3. HOPPER

CONVEYER BELT IS THE BELT WHICH IS USED TO TRANSFER THE COAL IN THE NEXT STATION FOR THE BETTER FULFILLMENT OF THE COAL IN THE BUNKER 12

4. CONVEYOR BELT

IT THAT TYPE OF CONICAL SECTION WHICH IS 6 OR 7 IN THE NUMBER IT STORE THE SMALL SIZE OF THE COAL WHICH IS LESS THAN 100 MM IT ALSO CONTROL THE SPEED OR FEED RATE OF THE COAL BEFORE ENTERING IN THE COAL MILL 13

5.BUNKER

COAL MILL IS THAT MILL WHICH IS USED TO PULVERISED THE COAL IN THE SMALL FORM WHICH IS LESS THAN THE SIZE OF 50 MM 14

6. COAL MILL

FURNACE IS A PLACE WHICH IS FOR THE BURNING OF THE COAL AS A FUEL TO INCREASE THE TEMPERATURE OF THE BOILER TO CONVERT THE WATER IN THE FORM OF STEAM
