Description:
The paper gives results of a study (in a turbulent spray flame) of the correlation between atomization quality and the destruction efficiency of hazardous organic compounds. The atomization quality was varied both by changing spray nozzle parameters and by inducing disruptive droplet combustion (secondary atomization) within the flame. The primary atomization quality was characterized by laser diagnostic size distribution easurements. The secondary atomization quality was determined from observations of disruptive atomization of intensity on a train of monodisperse droplets within a high-temperature laminar reactor. Study conclusions included: (1) degradation of atomization quality appears to influence target compound destruction efficiency by penetration of the largest droplets through the flame zone or to the wall, (2) hazardous compounds can cause disruptive combustion (secondary atomization) when diluted in fuel oils, and (3) the occurrence of secondary atomization was found to correlate with improved waste compound destruction efficiency in a turbulent spray flame operating in an atomizer limited mode.
