19193. Conclusion3. Conclusion

1. Air-Blown/Dry-Feed Gasifier & Low Btu/High Temp. GT⇒ Higher Plant Efficiency⇒ Higher Reliability w/ Long-Term Operation Experience

2. 250MW Demonstration Plant Starting Opperation⇒ Ensuring Quality/Performance of Commercial Plant

3. Various Coals Utilization⇒ Expected Plant Efficiency Is 43 - 46% (HHV Basis)

with “G” Type GT w/o Carbon Capture4. Carbon Capture Feasibility

⇒ Carbon Capture Consumes Aux. Power but Advantageof Higher Efficiency by Air-Blown IGCC Is Maintained

5. After Demonstration Plant Project ⇒ Ready for North American Commercial Plant Operation
