PRIMARY AIR SYSTEM

TURBINE – GENERATOR VIEW

COAL HANDLING PLANT

• SOURCE OF COAL : COAL INDIA LTD. BCCL,SECL & ECL• MEANS OF TRANSPORTATION: - RAILWAY

WAGONS • TYPE OF COAL : BITUMINOUS TAKEN TO COAL MILLS THROUGH

CONVEYOUR BELTS. CRUSHED INTO POWDERED FORM IN COAL

MILLS. WITH THE HELP OF PRIMARY AIR FANS IT IS TAKEN TO BOILER.

ASH HANDLING PLANT

THE WATER COMPOUNDED BOTTOM ASH RECEIVED IN ASH HOPPERS FROM FURNACE.

THEN DISCHARGED THROUGH CLINKER GRINDER

TWO SLURRY PUMPS FOR EACH BOILER. SLURRY IS DISCHARGED THROUGH PIPE

LINES.

WATER TREATMENT PLANT

• SOURCE OF WATER :- CHAMBAL RIVER• DIVIDED IN TWO PARTS :- 1. FILTERATION PLANT 2. DEMINERALISED WATER PLANT SUSPENDED PARTICLES ARE SEPARATED WATER IS TREATED WITH ALUM &

CHLORINE . THEN WATER IS PASSED THROUGH FILTER

BEDS. NOW WATER IS SEND TO D.M. PLANT.

WATER TREATEMENT PLANT

IN D.M. PLANT :- 1.) TREATED WITH CARBON FILTER 2.) ANION EXCHANGER 3.) CATION EXCHANGER 4.) MIXED BED 5.) DEGASIFIER 6.) DOSED WITH AMMONIA TO SET pH VALUE.
