FIELD: electrolytic production of aluminium. SUBSTANCE: atmospheric air heated to at least 100-450 C for account of electrolizer heat is fed into burner arrangement, air intake being controlled in proportion to difference in temperatures of preliminarily heated air and gas in mixing chamber of burner arrangement. EFFECT: increased efficiency of afterburning of anode gases, prolonged service life of gas collector and reduced carbon foam formation. 4 cl, 1 dwg, 1 tbl |
