The document provides details about the construction and working of a coal handling plant (CHP). It discusses key components of a CHP including wagon tipplers for unloading coal, conveyor belts for transporting coal, and three stages of crushers to reduce the size of coal pieces. The operational cycles of bunkering, stacking, and reclaiming coal are also summarized. The CHP properly handles and processes coal from receipt to transferring it to bunkers to supply coal to boiler operations.

10. Which properly handles the coal from its receipt to transferring it to bunkers. Objective of CHP :-To supply the quanta of processed coal to bunkers of Coal mills for Boiler operation.

12. Availability of Coal In India.Mostly E and F grade coal used in India.Blending Is Done To get Average D Grade.6/15/20105

13. Transportation of Coal5 ways of Transportation.1. Railways.

14. 2. Ropeways.

15. 3. Roadways.

16. 4. waterways.

17. 5. Airway.6/15/20106Best and Cheap facility at DoorstepAvailable only for TPS nearer to coal minesFear of thiefwaterway may not be possible till TPS and Problem of recalling arises if coal dip in waterHave to build Runway near TPS which is very costly.

18. By Rail Way80-90% of the requirement is fulfilled by this way.Demurrage calculations on coal Rakes:- We receive the coal wagons in the form of rakes (55-60 wagons in each rake).Free time normally 7 hrs. from Receipt of coal. Free time is calculated from the receipt of written intimation of coal rakes from MAHAGENCO to the railway.Rate of demurrage is Rs.100 / wagon / hr.6/15/20107

19. Analysis of CoalChemical Analysis of Coal:- Sample of coal is randomly collected from each rake and detailed chemical analysis, calculation of calorific value is carried out and is confirmed whether it is as per agreement with the coal mines or not.6/15/20108

26. Wagon TipplerThese are used to unload the coal wagons into coal hoppers in very less time (e.g. 20 wagons/hr. or more).Weighing of coal is carried out at wagon tippler. Normally 55-60 metric ton of coal come in each wagon.6/15/201015Wt of the coal =Wt. of loaded wagon – Wt. of empty wagon
