Abstract
Sistema di combustione a basse emissioni inquinanti per turbine a gas, del tipo a pre-miscelamento, in cui una serie di bruciatori paralleli, alimentati autonomamente con combustibile addizionale, è disposta circonferenzialmente attorno allo strozzamento di congiunzione della camera di premiscelamento con la camera di combustione, a creare nella zona di combustione immediatamente antistante detto strozzamento una corrispondente serie di fiamme addizionali di stabilizzazione della fiamma principale, l'aria di combustione per detti bruciatori essendo derivata dall'aria di raffreddamento della testata troncoconica della detta camera di combustione, che viene inviata ai bruciatori attraverso palette svirgolate per imprimere all'aria un moto sostanzialmente elicoidale.
