Abstract

L'apparecchio, costituito da un bruciatore atmosferico (10), da una camera di combustione (11) e da mezzi (13) per creare una depressione nella camera di combustione, comprende una struttura scatolare (23) che si raccorda con la camera di combustione e racchiude il bruciatore. Tale struttura scatolare presenta una o più aperture (26, 30) per l'aria secondaria (AS) e, in una parete (24) disposta trasversalmente tra gli ugelli (17) di uscita del gas e i condotti (18) di aspirazione e miscelazione del bruciatore, un'apertura (25) per l'aria primaria (AC) per ogni ugello.Per un migliore funzionamento in fase di accensione e in caso d'uso di gas tendenti al distacco di fiamma, la portata di aria primaria (AP), misurata nei condotti di aspirazione (18), viene ridotta, rispetto ai valori di regime con gas standard, aumentando la sezione dell'apertura, o delle aperture, per l'aria secondaria o riducendo la depressione in camera di combustione in funzione della portata del gas e/o della temperatura misurata in camera di combustione.The appliance, consisting of an atmospheric burner (10), a combustion chamber (11) and means (13) for creating a depression in the combustion chamber, comprises a box-like structure (23) which connects to the combustion chamber. combustion and encloses the burner. This box-like structure has one or more openings (26, 30) for secondary air (AS) and, in a wall (24) arranged transversely between the gas outlet nozzles (17) and the suction and mixing ducts (18) of the burner, an opening (25) for the primary air (AC) for each nozzle.For better operation during ignition and in the case of gases that tend to detach the flame, the primary air flow rate (AP ), measured in the intake ducts (18), is reduced, compared to the standard gas values, by increasing the section of the opening, or the openings, for the secondary air or reducing the depression in the combustion chamber as a function of the gas flow rate and / or temperature measured in the combustion chamber.
