Abstract (en)

A filtering-bed burner is described which comprises two concentric holding nets (9, 10) between which a space filled with granular elements of irregular shape (8) made of crystallized silicon dioxide is defined, said granular elements having a particle size included between 2.5 and 7 mm and defining a filtering bed (3) of a thickness included between 10 and 20 mm. An inlet header (4) and a closing element (5) are associated with the opposite ends of the filtering bed (3) and fastened to the corresponding edges of the holding nets (9, 10). The closing element (5) has a connecting portion (6) of the same form and size as the inlet header and a closing wall (7) axially delimiting a pre-mixing chamber (2) defined within the filtering bed. A hyperstoichiometric air-gas mixture is conveyed to the pre-mixing chamber (2) at a flow rate adapted to determine a specific flame power that can be modulated between about 25 W/cm<2> and 350 W/cm<2>. <IMAGE>
