Abstract
Due to the nature and depletion of fossil fuels, in recent years there is an increasing demand of sustainable, renewable, and alternative sources of energy. Valuable research is being conducted in many sectors of renewable energy and one such sector is hydrogen fuels, as it is a non-carbon-based fuel. However, due to the inherent issues with hydrogen storage, transportation, and safety, several potential hydrogen carriers are being investigated. One such hydrogen carrier that has shown promise as a green fuel is ammonia. It has a high hydrogen content and is thus a suitable chemical storage of hydrogen. However, pure ammonia flames are difficult to ignite as they have high ignition energy. Combustion of ammonia also produces oxides of nitrogen (NOx), which is a pollutant. There is also a chance of unburned ammonia slipping into the exhaust, which can be harmful as ammonia is toxic in nature.
Thus, the present study focuses on ammonia substituted hydrogen combustion. The ammonia-hydrogen diffusion flame lengths are studied in comparison to methane flame as a reference, to compare how ammonia-based fuels behave against traditional fuels. The NOx and unburned NH3 emissions are also investigated to find an optimum fuel blend which can easily replace traditional fossil fuels in industrial burners.
The present study provides a valuable data base that supports the combustion of green ammonia, which can safely replace traditional fuels.
