Hydrogen is carbon-free and is thus getting strong attention from the combustion community lately for its potential use as fuel in power generation and transportation sector. However, hydrogen flames come with challenges due to the strong reactivity and diffusivity of hydrogen which increase the risk of flashback. Furthermore, high levels of nitric oxides (NOx) can still be produced when burning hydrogen.
Within this context, recent research has revelead that, when intensively strained, NOx is significantly suppressed in in lean premixed hydrogen flames. In this presentation the physics behind intensively strained hydrogen flames and how NOx gets suppressed at these conditions is first discussed. The presentation will continue with the state-of-the-art in combustion designs for hydrogen-fuelled systems and perspective of application of the highly strained flames concept.
