... fuel consumption while minimizing exhaust emissions. Ammonia (NH 3 ) is one of these candidates, as it has historically been shown to provide high energy potential and zero-carbon emission (CO and CO 2 ) (Hayakawa, A., Goto, T., Mimoto, R., Arakawa, Y., Kudo, T., and Kobayashi, H., 2015, “Laminar...

... to its chemical and physical properties, ammonia is gaining more and more interest. This work investigates an innovative ammonia-to-power system based on an SOFC-mGT HS, focusing on thermodynamic parameters, system features, and technical and environmental challenges. A MATLAB/Simulink model, built...

... reduced/zero carbon emissions. One such fuel is ammonia (NH 3 ). However, ammonia is hard to ignite, has a low flame speed, and produces a significantly large amount of nitrogen oxide (NO x ) emissions. Hence, using 100% ammonia as fuel in gas turbines requires significant modifications...

... ammonia and hydrogen are zero-carbon energy vectors, their physical properties and burning characteristics sit on either side of that of natural gas. Hence, mixtures of ammonia and hydrogen are being increasingly looked at as having the potential to fuel current energy systems without requiring...

...Jordan Davies; Luca Mazzotta; Daisuke Sato; Syed Mashruk; Daniel Pugh; Domenico Borello; Agustin Valera-Medina Interest in using renewably produced, partially cracked ammonia in gas turbines is gaining traction, but challenges relating to emissions of NO x and unburned ammonia remain. This work...

Marsh Renewably generated ammonia offers a form of carbon-free chemical energy storage to meet the differences between uncertain supply and fluctuating demand and has the potential to support future...

...Jiabo Zhang; Anhao Zhong; Zhen Huang; Dong Han A theoretical analysis based on the second law of thermodynamics was conducted for the ammonia/hydrogen/air premixed flames at different initial pressures. The irreversibility causing exergy losses in premixed flames was divided into five parts, namely...

..., as too great a temperature difference is unfavorable. This work evaluates the benefits of coupling the economizer and the reboiler in a specially designed CCPP. In the CO 2 separation plant both monoethanolamine (MEA) and ammonia are evaluated as absorbents. Higher regeneration temperatures can...

... temperature of medium-Btu gasified fuel used in this system is high so that N O x formation by nitrogen fixation results to increase significantly. Additionally, the gasified fuel contains nitrogenous compound, as ammonia, and it produces nitrogen oxides, the fuel N O x , in the case of employing the hot/dry...
