The paper shows results of continuos research of multi-hole effervescent atomizers for industrial burners. The atomizer is powered with light heating oil and uses air as an atomizing medium. Here we focus on several new versions of multi-hole effervescent atomizers developed on the basis of previous research. Detailed description of spray quality is presented. 3-D graphs show spatial distribution of Sauter Mean Diameter and mean velocity. Influence of design and operational conditions on spray quality is analyzed. Size-velocity correlation and size and velocity distribution is described. The results are compared with results of other authors. Two-phase flow inside the atomizers is described by Bakers map for horizontal flow. Our previous results with two-phase flow visualization invoked a possibility of liquid-gas gravitational separation. Results of spray heterogeneity measurements show that differences between fuel flow rate of individual holes can be of the order of tens %. Effervescent atomizer sprays tend to be unsteady under some operating conditions. Spray unsteadiness at lower pressure and GLR were observed and measured.
