Oxyfuel燃烧被视为对未来清洁煤技术捕获二氧化碳捕获的主要选择之一。该论文通过基础澳大利亚/日本的Oxyfuel可行性项目的基本研究提供了有关研究活动和技术开发的概述。介绍了对试验液炉和实验室尺度液滴管炉的氧气燃烧的研究，并将其与计算流体动力学（CFD）预测进行了比较。这项研究为当前知识做出了一些贡献，包括：对试验尺度的氧气燃料中的氧燃料燃烧的全面评估，通过匹配传热来修改氧改造的设计标准，这是一种新的4灰色气模型，可以准确预测用于氧气炉中气体的发射率建模，在实验室和试点规模的空气和氧气中的煤反应性比较的首次测量；并预测氧气射击中的火焰点火延迟。 （c）2009化学工程师机构。由Elsevier B.V.保留所有权利。
Oxyfuel combustion is seen as one of the major options for CO2 capture for future clean coal technologies. The paper provides an overview on research activities and technology development through a fundamental research underpinning the Australia/Japan Oxyfuel Feasibility Project. Studies on oxyfuel combustion on a pilot-scale furnace and a laboratory scale drop tube furnace are presented and compared with computational fluid dynamics (CFD) predictions. The research has made several contributions to current knowledge, including; comprehensive assessment on oxyfuel combustion in a pilot-scale oxyfuel furnace, modifying the design criterion for an oxy retrofit by matching heat transfer, a new 4-grey gas model which accurately predicts emissivity of the gases in oxy-fired furnaces has been developed for furnace modelling, the first measurements of coal reactivity comparisons in air and oxyfuel at laboratory and pilot-scale; and predictions of observed delays in flame ignition in oxy-firing.
