Advanced power generation using new coal combustion technologies increases energy efficiency and makes carbon dioxide capture possible, but increases the corrosion problems. This project aims to determine the corrosion behaviour of chromia-scale forming iron- and nickel-base alloys in the presence of deposits (coal ashes and salts) under carbon dioxide rich gas atmospheres. The increased understanding of alloy behaviour in hot corrosive ashes and gases, will permit more effective materials design and selection leading to more efficient and economic technologies for reliable and low cost carbon capture in energy production, waste-energy conversion and related industries.

使用新型煤炭燃烧技术的先进发电提高了能源效率，并使二氧化碳捕获成为可能，但也增加了腐蚀问题。该项目旨在确定在富含二氧化碳的气体气氛下存在沉积物（煤灰和盐）的情况下形成氧化铬垢的铁基和镍基合金的腐蚀行为。对热腐蚀性灰烬和气体中合金行为的更多了解将允许更有效的材料设计和选择，从而产生更高效、更经济的技术，在能源生产、废物能源转化和相关行业中实现可靠和低成本的碳捕获。
