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
