Abstract

The throughput of atomising liquid nozzle is greatly increased by adding a second outer annular gas channel around the outside of the two inner liquid nozzles. Particularly for mixing acidic and basic liquids. Inner nozzle air channel projects somewhat beyond outer annular channels and outer wall is conical shaped. Ratio of area of inner gas channel to outer gas channel is 1 to 3-10.
