✦ Synopsis

An investigation has been conducted into the effects of introducing additional diluents into the primary air stream of pressure-jet and air-blast atomizers on their flame characteristics. The effects of primary air/fuel ratio and concentration of diluent (N 2 or CO2) on flame appearance, flame length, fraction of heat release radiated, temperature profiles, and oxygen concentration profiles in the spray flames of ASTM number 2 fuel oil and kerosene are presented. The results show that the structure of flames from both types of atomizers is significantly affected by the additional diluents. Flame length, emission of soot, and fraction of heat release radiated all decrease with an increase in the amount of additional diluent in the primary air.
