基于液体燃料的多孔介质燃烧技术研究现状

A Review of Liquid Fuel Combustion in Porous Media

对国内外近年来关于多孔介质燃烧技术在液体燃料燃烧领域的实验及数值模拟研究做了较为全面的综述和分析。分析表明:多孔介质燃烧技术为液体燃料提供了一种可能的先进燃烧方式。相较于传统自由空间内的火焰燃烧,多孔介质燃烧技术可改善液体燃料的雾化、蒸发,获得低排放、高稳定性、宽负荷比的燃烧表现。该技术在燃油锅炉、燃气轮机、斯特林发动机等领域拥有广阔的应用前景。

A comprehensive picture is given on the research and developments on combustion of liquid fuels in a porous media, including experimental and numerical research. The analysis results show that the technology of combustion in porous media is an advanced and possible combustion approach for liquid fuel. Compared with the conventional combustion in free space, the porous media combustion could im- prove the liquid fuel＇ s atomization and evaporation, and features low emissions, strong flame stabilization and wide turn-down ratio. This technology could be widely applied in related fields, including oil boilers, gas turbines and Stifling engines.
