REQUIRED COAL CONSUMPTION :- As per Boiler Design Coal Consumption :-
Daily Coal Requirement = 49,500 TPD For Six Unit. = 343 TPH Per Unit(Approx.) Design Capacity = 1950 TPH Capacity for Three
Units. Bunker = 42 Nos. Each Unit = 07 Nos. ( 05 Nos. in Operation at a time). Bunker Capacity = 1100 MT (Approx) coal.
