Abstract
L'invenzione riguarda un corpo di camera di combustione di una turbina a gas con un gomito di entrata (8) applicato lateralmente per l'aria del compressore, che attraverso un diffusore di entrata (6) viene distribuita uniformemente sul cono forato (9), rimbalza ivi sul tubo di miscelazione (10) e viene deviata verso l'alto in direzione del tubo di fiamma e del bruciatore.In determinati stati di funzionamento della turbina a gas è necessario strozzare la corrente di aria primaria diretta al bruciatore, senza dover ridurre la potenza del compressore collegato a monte.Ciò avviene secondo l'invenzione per il fatto che alla parte inferiore della camera di combustione viene collegato un condotto di bypass (3) con compensatore (1) e valvola di regolazione (2), attraverso il quale una parte dell'aria proveniente dal gomito di entrata dell'aria (8) viene convogliata direttamente attraverso un tubo di afflusso (4) nell'interno del tubo dì miscelazione (10).
