I processi selettivi non catalitici di riduzione (SNCR) degli ossidi di azoto consistono in essenza nell'iniezione di un agente di riduzione nella corrente dei fumi di combustione. Lacinetica chimica dei processi Thermal DeNOx e NOxOUT, che coinvolgono rispettivamente l'addizione di ammoniaca e urea, è stata investigata sperimentalmente utilizzando un reattoredi laboratorio (CSTR). In particolare, è stato studiato l'effetto delle concentrazioni iniziali dei reagenti e della temperatura. Confronti tra le predizioni ottenute utilizzando diversi modelli cinetici dettagliati per il processo Thermal DeNOx presentati nella letteratura hanno evidenziato che questi modelli nonsono in grado di predire correttamente gli andamenti sperimentali nelle condizioni operative investigate. Uno di questi modelli è stato modificato con l'obiettivo di riprodurre i risultati sperimentali e di fornire uno strumento di simulazione in un ampio intervallo di condizioni. I nuovi risultati sperimentali sono stati anche utilizzati per la modellazione del processo NOxOUT. La potenzialità di due diversi approcci per modellare l'influenza della miscelazione tra le correnti dei reagenti è stata infine investigata. Il primo approccio accoppia alla descrizionedettagliata della cinetica chimica un modello semplificato di reattore. La seconda metodologia di calcolo utilizza un codice di fluidodinamica computazionale per la descrizione rigorosadella fluidodinamica insieme a una modellazione semplificata della cinetica chimica. L'affidabilità di entrambi i metodi è stata verificata confrontando le predizioni ottenute con risultati sperimentali presentati nella letteratura per il processo Thermal DeNOx. Infine, l'influenza della miscelazione sull'efficienza di abbattimento di NO è stata discussa con riferimento ai tempi caratteristici di miscelazione e reazione.

This research evaluates the use of selective non-catalytic reduction (SNCR) for the removal of oxides of nitrogen (NOx) in a jet engine test cell (JETC). The plume effluent in the exhaust stream of a TF30-P111+ and a TF33-P9 engine in a jet engine test cell was first characterized. A test stand and five-point sample probe were designed and built to make measurements directly behind the engine nozzle. Data were collected in conjunction with actual engine tests. Temperature, NOx, carbon monoxide (CO) concentration, and velocity were among the characteristics measured radially and axially in the plume. These parameters were used to determine baseline conditions for the chemical kinetic modeling of SNCR using ammonia, cyanuric acid, urea, and hydrazine with additives of hydrogen, methane, and hydrogen peroxide. The measurements revealed that temperatures are marginal for the application of SNCR in JETCs except at high throttle and afterburner settings on the P111+ engine. The chemicals themselves have limited range of applicability. Additives help to extend their usefulness, mostly by shifting the temperature window down. Urea and hydrogen peroxide yielded the best range of the chemicals tested. However, this combination may reduce NOx in the entire exhaust stream by up to only 25% at military power on the high-performance P111+ engine. The findings of this work have attractive implications for non-JETC applications operating near the same conditions.
