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.
