FIELD: metallurgy.
SUBSTANCE: slit burner of aluminium electrolyser with a self-baked anode consisting of a cylindrical heat exchanger with slits and a pipe for supplying anode gases in its lower part, the slits of the cylindrical heat exchanger are made as a variable area descending towards the anode gases supplying branch pipe with a ratio of the previous to the following as S1: S2…: Sn=(1:0.7÷0.5…0.5÷0.2), where S1: S2…:Sn is the area of the slit of the cylindrical heat exchanger burner, m2.
EFFECT: increased efficiency of mixing the flared anode gases, increased service life of the burner.
