Abstract

Un complesso di combustione comprende un combustore avente camicie interne ed esterne, e mezzi di combustione a stadio pilota ed a stadio principale disposti tra le camicie. Un distributore di turbina si unisce alle estremità a valle delle camicie interne ed esterne del combustore e il mezzo di combustione dello stadio principale è strettamente collegato al distributore di turbina per ottenere un tempo breve di permanenza della combustione dei gas di combustione dello stadio principale per ridurre l'emissione di NOX. In una realizzazione preferita ed esemplare dell'invenzione, il complesso di combustione comprende una prima ed una seconda pluralità di iniettori di combustibile spaziati circonferenzialmente e formatori di vortici disposti radialmente all'esterno di una pluralità di parafiamma cavi spaziati circonferenzialmente aventi fori di scarico del combustibile. La combustione dello stadio pilota è effettuata a valle degli iniettori di combustibile primario e secondario e dei formatori di vortici, e la combustione dello stadio principale è effettuata a valle dei parafiamma. I parafiamma sono disposti a valle degli eiettori di combustibile primari e secondari e dei formatori di vortici e sono strettamente connessi al distributore della turbina per ottenere il breve tempo di permanenza di combustione.
