description Under the guidance of the "double carbon strategy", as a new type of zero-carbon fuel, ammonia has gradually attracted attention. To solve the issues of ignition, low flame speed, and narrow flammable range of ammonia combustion, from the basic combustion characteristics, we summarize the effects of enhanced combustion technologies such as improving fuel activity (blending with other fuels and oxygen-enriched combustion), heat-mass transfer enhancement, and auxiliary combustion technologies on flame propagation, and explore the mechanism of the enhanced combustion process. Co-combustion with other fuels can significantly increase the ammonia flame speed, and hydrogen has the strongest ability to enhance combustion. The laminar flame speed of ammonia/air increases exponentially with the hydrogen blending ratio. With the increase of the carbon-based fuel blending ratio, the ammonia/air flame speed increases linearly. Oxygen-enriched combustion can significantly increase the ammonia flame speed without carbon emission, and laminar flame speed increases linearly with oxygen content. The ability to regulate parameters to enhance combustion is limited, while the auxiliary technologies can be flexibly applied for different combustion conditions to enhance ammonia combustion. In the development of ammonia enhanced combustion technology, the regulation of fuel combination and injection strategy can be applied to improve fuel activity, designing the burner structure/combustion organization, and optimizing the combustion parameters can be applied to enhance heatmass transfer. In addition, coupling with auxiliary technologies can enhance combustion performance and widen the stable combustion range. Combustion enhancement and NO_x emission control are of great significance to realize clean and efficient ammonia combustion in the future.
