Abstract

A gas black burner is described which is used normally in connection with a rotating cooling roller as a deposition surface, so that its discharge openings for the operating gas containing the raw material for the carbon black are directed against the cooled deposition surface. The burner is characterized by the fact that it is formed as a pipe shaped chamber provided with at least one supply line and disposed in parallel relationship to the deposition surface, which chamber has slit shaped discharge openings in its jacket. The invention relates to a gas black burner with openings to be directed against a cooled deposition surface.
