No Outdoor Coal Stock Yard
No Discharge
No Ash Pond
• No Visible Coal Storage • Ash Recycling • Waste Water RECYCLE
Plant Site with Non-visible Coal Storage

Plant Site with Non-visible Coal Storage
Environmentally Unfriendly Disposal of Ash Waste
No Ash Pond
Existing Power Plant
No Ash Pond
Ash handling system
100% recycling
- Using bottom ash for light aggregate, fly ash for cement
- Remaining ash will be used for mine back fill
- No need for an ash pond

Water & Waste Water Treatment : No Waste Water Discharge
Zero discharge by closed loop system of
water & waste water treatment system
Ⅳ. Clean Energy Production
1. SNG
KOSPO operates a number of CCPP
Hard to introduce LNG directly
Coal gasification as an alternative fuel
Coal gasification using low grade coal
Keep in LNG storage tank &
use for CCPP alternative fuel
SNG
2. Small Hydro-power
Using discharge
Capacity : 5,500 kW (1,375kW x 4
Units)
Type : Kaplan
