Abstract

L'invenzione si riferisce ad un'unità di combustione, che comprende una camera di un reattore, la cui parte inferiore, per formare un letto fluido, è munita di una struttura a grata (10), almeno un separatore di particelle con dei mezzi per purificare il gas di combustione contenente materiale solido, l'unità di combustione comprendendo inoltre un condotto di ritorno (6a) per far ritornare il materiale solido verso il letto fluido. Una struttura d'arresto del. gas (KL), impedisce al gas di fluire in direzione opposta, e comprende una combinazione formata da una struttura di base chiusa (14), una struttura superiore di copertura (11) che si trova al disopra della struttura di base (14) e avente delle aperture (12a), e inoltre uno spazio intermedio (13) formato tra la struttura di base (14) e la struttura di copertura (11), e delle aperture (15a) che si trovano sulla parete della conduttura di ritorno (6a).(FIG. 2)
