Description:
The report is a technoeconomic appraisal of the integrated (coal) gasification combined-cycle (IGCC) system. lthough not yet a proven commercial technology, IGCC is a future competitive technology to current pulverized-coal boilers equipped with SO2 and NOx controls, because of its potential for increased thermal efficiency and very low emission rates. owever, its not yet being proven commercially will influence its rate of market penetration and its possible impact on future emissions. he first IGCC plant to supply electricity to a U.S. utility system has been demonstrated at Southern California Edison's Cool Water Generating Station near Barstow, CA, using Texaco's coal gasification process. his demonstration has provided significant data for process improvements and has indicated the basic operability of combined chemical process/power generation technology. owever, remaining technical questions include: lant operation over an extended period with high sulfur eastern coal; operability of the Texaco gasifier at full throughput; materials of construction; and plant availability/reliability. ne advantage of IGCC systems is their potential for phased construction of partial plant capacity to more closely match the currently slow electricity demand growth. imple comparisons indicate similar electricity generation costs for IGCC and competing technologies.
