The project is aligned with the Low Carbon Energy Technologies priority. Specifically, the proposal is focussed on the development of oxy-fuel firing as a carbon abatement technology, and directly targets the key themes of Combustion technologies that improve plant efficiency and reduce CO2 emissions and Carbon capture technologies, from pre- or post-combustion or oxy-fuel firing technologies . As indicated in the UK Government's Carbon Abatement Technology Strategy (DTI/Pub UR 05/844, June 2005) future thermal power plants will be configured to minimise CO2 emissions. Pulverised coal-fired plant, operating in oxy-fuel firing mode and specifically designed for CO2 capture, has been identified in IEA studies to be a highly competitive clean coal power generation technology, ideally suited to new build advanced/ultra-supercritical plant or for retrofit to existing plant. This project aims to advance the current state-of-art in oxy-fuel firing by addressing critical technology gaps ahead of extensive component testing, plant design and demonstration. The project objectives are: i) to understand the effect of coal type on oxy-fuel combustion; ii) to determine the impact of oxy-fuel on slagging, fouling, & high temperature corrosion; iii) to develop a novel process for NOx/SO2 removal & CO2 purification; iv) to undertake pre-engineering for the testing of a full-scale oxy-fuel burner; and v) to assess reliability, availability, maintainability & operability (RAMO) and safety issues relating to oxy-fuel firing.

该项目符合低碳能源技术优先事项。具体而言，该提案侧重于开发作为碳减排技术的富氧燃料燃烧，并直接针对燃烧技术的关键主题，即提高工厂效率和减少二氧化碳排放以及碳捕获技术，从燃烧前或燃烧后或富氧燃料燃烧技术。正如英国政府的碳减排技术战略（DTI/Pub UR 05/844，2005年6月）所指出的，未来的热电厂将被配置为最大限度地减少CO2排放。在全氧燃烧模式下运行并专门为CO2捕获而设计的煤粉燃煤电厂已在IEA研究中被确定为具有高度竞争力的清洁煤发电技术，非常适合新建先进/超超临界电厂或改造现有电厂。该项目旨在通过在广泛的组件测试、工厂设计和演示之前解决关键技术差距，推动当前最先进的全氧燃料燃烧技术。该项目的目标是：i）了解煤种对富氧燃烧的影响; ii）确定富氧燃烧对结渣、结垢和高温腐蚀的影响; iii）开发NOx/SO2去除和CO2净化的新工艺; iv）进行全尺寸富氧燃烧器测试的前期工程;以及v）评估与氧燃料燃烧有关的可靠性、可用性、可维护性和可操作性（RAMO）以及安全问题。
