1 1 Introduction to Korea IGCC Development Program Dr. Ahn, Dal-Hong

2 2 IGCC Overview m Integrated Gasification Combined Cycle (IGCC) - Power plant combining a Gasification system with a CC - Coal is converted into a raw synthesis gas (syngas), mostly CO and H 2, in a gasification system. The raw syngas is cleaned and then used to produce electricity in a CC power plant m Features - High efficiency: current 39~42% (HHV, Net) Up to 45~46% with advanced GT - Environment friendly : SOx 99.9%, NOx 25ppm - CCS ready : 90% of CO 2 - Flexible feedstock : Coal, Biomass, Waste, Oil Residue m Disadvantages - High capital cost, Complex configuration
