Experimental Study of Pressure Swirl Atomizers for Lead Oxide Production
Abstract
In this experiment, swirl injectors were designed and tested to validate their use in spraying liquid lead into a Barton pot combustion chamber to produce lead oxide at a smaller particle size than the current stream injection. Testing was done with water and air to determine the best design for atomization results, and then the injector was fabricated for liquid lead testing. Thermochemistry calculations showed that due to lead oxidation being a surface reaction, the combustion process was diffusion controlled. These conditions were used to determine residence time inside a Barton pot combustion chamber for predicted droplet sizes. Results of the liquid lead testing showed that final lead oxide particle size and residence time was reduced when using a swirl atomizer in place of a steady feed stream. Further calculations were done to create a model for a standard combustion chamber and injection system for lead oxide production.
