Abstrakt: Oxy-fuel combustion is expected to be one of the promising systems on CO2 capture from pulverized-coal fired power plant, and enable the CO2 to be captured in a more cost-effective manner compared to other CO2 capture process. Some studies in this area were implemented under Australia-Japan consortium established in 2004. The comparative testing of the important components by using three Australian coals has been recently conducted under both oxy-fuel and air combustion conditions. The purposes of these tests were to obtain design data on flame stability, combustion characteristics and plant operation including turn-down test. The tests have indicated a number of important outcomes including a good comparison of normal air with oxy-fuel combustion, significant reduction in NOx mass emission rates under oxy-fuel combustion and the collection of data to validate other combustion modeling work. On the basis of the study results, the project under Australia-Japan consortium is now under way for applying oxy-fuel combustion to an existing plant by way of demonstration. This project aims at capturing CO2 from an actual power plant for storage. The project will be implemented at the power generation system in Callide-A power plant No.4 unit with a capacity of 30MWe in Australia. [ABSTRACT FROM AUTHOR]
