Abstract: A potential enabler of a low carbon economy is the energy vector ammonia, which is a carbon free carrier with high energy density. Hence, it is proposed that ammonia, with its established transportation network and high flexibility, could provide a practical next generation system for energy transportation, storage and use for power generation. Therefore, previous studies and ongoing research are presented to use this chemical as a viable energy vector for power applications, emphasizing the challenges before implementation and commercial deployment is achieved at a larger scale. The talk covers fundamental research results on ammonia combustion are presented including ignition delay times, laminar flame speeds, species concentration profiles, oxidation chemistry, laminar and turbulent flames structures. Ammonia flame stabilization behaviors and emission characteristics are presented and discussed by using a gas turbine combustor. Injection and co-firing strategy in swirl combustors and the combustion enhancement will also be addressed. A better understanding on emission controls over the combustion on NOx mitigation and other techniques will be revealed.
