제목 Oxy Fuel Combustion Technology for CO2 Capture
초록 To reduce the C02 Emission for climate change is an important issue in Korea, which produce GHG of about 5.9 Million tons of C02 per year. Especially the share of C02 from thermal power plant is around 25% of total GHG emission in Korea.
Oxy-fuel combustion has been known to have many options to enhancing economic efficiency compared with other C02 capture technologies such as post- combustion and pre- combustion technology.
Oxy-Combustion R&D program for developing an oxy-pulverized coal power plant in the 100MWe class in Korea had launched from 2007 and will be passed through 3 phases for total 8 years. The main goal for this long-term ambitious project is to build oxy-pulverized coal power plant in Korea at first.The main goal for the first phase of this research for 3 years program is setting up the conceptual design for an oxy-pulverized coal boiler in the class of 100MWe and conceptual design of optimization of power plant system.
100MWe sub-bituminous coal plant with 90% CO2 capacity factor and 90% efficient capture would produced CO2 stream mass of 1.0 million ton per year. Young-Dong #1 power plant which will be Demonstration Plant of Oxy-combustion project would be re-constructed boiler system. Through the research of optimization of Oxy-PC power plant, the boiler and auxiliary facilities will be constructed except the existing facilities such as the turbine system and its subsidiary in Young-Dong power plant using sub-bituminous coal as design coal.
Young-Dong power plant has 125MWe power and 402ton/hr steam generation capacity and the main steam temperature is 541℃. It had begun commercial operation in 1973 and will be shut down by 2013. The conceptual design of Oxy-PC power plant will be presented after finishing development of the design tool for conventional air combustion power plant using the existing CFD code for verifying the reliability of that.Oxy-PC power plant system needs more high efficient dust removal technology than conventional air firing system due to the recirculation of flue gas, and also does development of advanced dry de-sulfurization technology due to much more of increasing dry de-sulfurizing efficiency in oxygen-rich ambience compared with air firing system.
