Abstract

Secondo l'invenzione il bruciatore per la combustione di combustibili fluidi prevede a valle dell'ugello di polverizzazione (2) e in corrispondenza della zona del condotto di combustione una pluralità di feritoie (8, 68, 78) che sono allineate lungo il loro asse maggiore in direzione circonferenziale al condotto di combustione in una o più file disposte in prossimità della zona di massima depressione. Secondo una preferita forma di esecuzione le feritoie sono praticate nel condotto di combustione. Secondo un'altra forma di realizzazione le feritoie (78) sono realizzate in corrispondenza della sezione trasversale in cui il condotto di combustione (75) si innesta al condotto di alimentazione (74). Secondo un'altra esecuzione le feritoie (68) sono praticate in una corona circolare disposta in corrispondenza della sezione trasversale in cui il condotto di combustione (65) si innesta al condotto di alimentazione (64).According to the invention, the burner for the combustion of fluid fuels provides downstream of the spray nozzle (2) and in correspondence with the area of the combustion duct a plurality of slits (8, 68, 78) which are aligned along their axis greater in circumferential direction to the combustion duct in one or more rows arranged near the zone of maximum depression. According to a preferred embodiment, the slits are made in the combustion duct. According to another embodiment, the slots (78) are made at the cross section in which the combustion duct (75) engages the supply duct (74). According to another embodiment, the slits (68) are made in a circular crown arranged at the cross section in which the combustion duct (65) engages with the supply duct (64).
