Original abstract

Our work is being conducted with the aim to develop an effervescent atomizer for industrial burners that will generate a fine and stable spray in large turn-down ratio. The single-hole, plain orifice atomizer is powered with light heating oil and uses air as an atomizing medium in the "outside-in" gas injection configuration. Published design concepts of the effervescent atomizer are described. Based on the published results several design parameters are modified: size and number of aerator holes, their location and diameter of the mixing chamber. Influence of these parameters on spray performance is studied at atomizing pressures 0.1, 0.3 and 0.5 MPa and gas-to-liquid-ratio (GLR) of 2, 5 and 10%.
