...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...

...P. Di Gloria; M. G. De Giorgi; L. Strafella; G. Ciccarella; G. G. Castelluzzo; F. Baldassarre; A. Ficarella Our study investigates the impact of nanoparticulate additives—specifically those based on ammonia and water—on the combustion characteristics of Jet-A1 aviation fuel, using a 300-kW liquid...

...Yousef M. Almarzooq; Matthew Hay; Maryam Khan-Ghauri; Olivier Mathieu; Waruna D. Kulatilaka; Eric L. Petersen Interest in ammonia (NH 3 ) in combustion has increased in recent years as a carbon-free fuel alternative. Therefore, understanding its combustion characteristics is crucial. One way...

... =   NO 2 +   OH is initiated and promotes OH radical production. Figure 12 shows (R10517) to be an ignition promoting reaction for stoichiometric mixtures of NG/NH 3 . Although this reaction sequence is also be driven by fuel NO from ammonia, energy is first required to break N-H bonds...

...D. Pugh; A. Valera-Medina; P. Bowen; A. Giles; B. Goktepe; J. Runyon; S. Morris; S. Hewlett; R. 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...
