Characteristics of ammonia combustion and modern studies of combustion stabilization

Abstract

BACKGROUND: The paper addresses the issues of ammonia combustion, such as ignition difficulties, low combustion stability, and high NO_x emissions. The importance of understanding the basic characteristics of ammonia combustion is emphasized, the existing stabilization technologies are reviewed.

AIM: Analysis of the aspects of ammonia combustion stability in various types of engines and necessity for further research in the field of using ammonia as a fuel.

METHODS: Various methods are applied, including visual flame analysis, ignition delay analysis, emission characteristics studies, heat transfer improvement methods such as high oxygen pressure, and external assistive technologies, including plasma.

RESULTS: The study presents comprehensive results on the characteristics of ammonia combustion. It includes a detailed analysis of flame behavior, ignition delay, and emission profiles. The effectiveness of different fuel mixtures and combustion conditions to improve the stability and efficiency of ammonia combustion is also explored.

CONCLUSIONS: The paper highlights prospects and challenges in using ammonia as a fuel source. The importance of further research and development in the field of ammonia combustion technologies is emphasized, especially in the context of achieving carbon neutrality and adapting to various application scenarios.
