The mixing arrangement is adjoined at a gas supply nozzle part (2), which is tapered in a direction of the mixing arrangement, and opens into the inlet zone. The mixing arrangement comprises an inlet opening (4) for the liquid in the inlet zone. A ratio of diameter of a gas outlet opening (2a) of the gas supply nozzle and internal diameter of the mixing arrangement in the inlet zone is in a range from 1:3 to 1:5.
