Prospect of clean coal technology in Korean utility sector
- Korea Electric Power Research Inst. (Korea, Republic of)
This paper will describe the status and prospect of Clean Coal Technology (CCT) in Korean utility sector. KEPCO needs new technologies with low cost, stable price and excellent environmental performance for power generation. Therefore, the CCTs such as FGD, CFBC and IGCC are considered to be the candidate technologies for SO{sub x} control. FGD System is the prime candidate for the SO{sub x} control of thermal power plants. All power plants should be installed with FGD after January 1999. For the New Thermal Power Plant, FGD System will be installed at the same time of main construction period. For the existing Thermal Power Plant, low sulfur coal will be used before the end of 1998, and also FGD system will be installed gradually by the end of 1998. Tonghae CFBC Power Plant is under construction to use Korean anthracite coal, containing 4% volatile matter, 39% ash, and a heating value of 4,600 Kcal/kg. Plant capacities are 2 units of 200 Mwe electricity. Its technology is based on the ABBCE CFBC System. Plant gross efficiency is 39.1%. NOx emission level is 250 ppm, and SO{sub x} emission is 180 ppm. The planned commercial operations of No.1 and No.2 units will be in June 1998 and in June 1999, respectively. The IGCC is superior to all other power generation technologies in terms of efficiency and emissions except it has a high capital cost. However, the authors think IGCC will gradually replace some pulverized coal power plants by the 21st century. The strategy of developing IGCC in Korea is based on the technology transfer from commercial vendors and internal R and D Program for the core technologies of IGCC. KEPCO is planning to install a Clean Coal Technology by year 2005. Technology will be determined between IGCC and PFBC. In case IGCC selected, technology transfer and commercialization of IGCC in Korea will be implemented in three phases. The Phase 1 is IGCC Process Evaluation from 1993 to 1996. The Phase 2 is the Feasibility Study from 1997 to 1998. The Phase 3 is 300MW IGCC Commercialization and Technology Transfer from vendor. Clean Coal Technology will be essential for the 21st century in order to meet the stringent Environmental Regulation after January 1999. All PC plants will be installed with FGD Systems before Dec. 1998. Tonghae CFBC (2 Unit 200MW) will be installed by June 1998. KEPCO`s Long Term Power Plan included 300MW FBC or IGCC by year 2005.
