The article describes the analysis of gas-liquid ejection apparatuses designs. The authors consider the trends of design for innovative apparatuses, anddwell on implementation for devices using the process of liquid atomisation. The conducted experimental studies allow us to assess the efficiency of gas-liquid ejection apparatus. The article considers the experimental dependences of the "sulphite number" on the pressure drop across the nozzle and the ejector diameter.
