CARBON SHUTTLE ARE DOWNLOADED FROM A SCAFFOLD OVERHEAD RAILWAY
AFTER DOWNLOADING COAL IS TAKEN OVER FOUR CARS TRANSPORTED ON RUBBER CONVEYORS, CRUSHING JAW CRUSHERS AND TWO SORTING GRIDS WITH TWO ROTATING BARS IS OBTAINED UP TO 30mm IN SIZE
AFTER CRUSHING COAL BUNKERS ARE DELIVERED DIRECTLY TO THE COAL SUPPLY BOILERS OR DEPOSITED IN THE COAL, THUS ENSURING STOCK FOR THE WINTER

PREPARATION OF PROCESS WATER
THIS SECTION PROVIDES THE TECHNOLOGICAL PROCESS IN THE COLLECTION, TREATMENT, AND DISPOSAL OF ALL CATEGORIES OF WATER RESULTING FROM THE ACTIVITIES

THE MAIN SOURCE OF INDUSTRIAL WATER S.C. CET FROM THE RIVER WATER IS DRAWN NECESSARY THROUGH A PUMPING STATION EQUIPPED WITH FOUR PUMPS TYPE MV 253
IT IS THEN PUMPED TO AN UNDERGROUND PIPE WITH CET DN=800mm AND LENGTH L = 12,332 M
IN TIMES OF FLOODS OR RIVER, WHEN NOT USING WATER FROM THIS SOURCE
(OR PUMP STATION SHUTDOWN DURING) USING DEEP WELLS DRILLED INSIDE CET

WATER PREPARATION TECHNOLOGY INCLUDES THE FOLLOWING PROCESSES:
-PUMPING WATER FROM SOURCES
-PREHEATING THE RAW WATER (DURING WINTER)
-PREPARATION OF REAGENTS FOR PRETREATMENT, SOFTENING, DEMINERALIZATION
