To provide fundamental knowledge required for the future utilization of practical electrostatically assisted oil spray flames. To determine the scope and means for reduced emissions, increased thermal efficiency, increased turndown and reduced costs compared with conventional atomization.RESEARCH PROGRAMMERecent advances in understanding have made possible the injection of significant electrical charge into insulating fluids such as hydrocarbon oils, flowing through a nozzle. With high enough charge the emerging liquid is subjected to very strong electrostatic forces which counteract surface tension and can enhance the breakup into droplets (atomization). Furthermore, the charged spray can be modified by applying electric fields. There has been remarkably little research into modifying oil sprays in this way nor has there been significant work on the burning of such sprays and investigating the potential advantages in terms of pollutant emissions reduction and improved efficiency. The experimental and theoretical investigation has commenced by designing and constructing an electrostatic oil atomizer. A systematic series of tests have measured drop size and spray current for variation in type of liquid, flow rate and applied voltage. At later stages optimised designs will be tested under burning conditions. Computational Fluid Dynamics models are being developed for the charged sprays. Fluid flow and current fields in the nozzle are also being modelled.
