A uniform-spray-stream burner for microgravity experiments was newly developed. Partially-prevaporized sprays were continuously generated by the condensation method. Mean droplet diameter of spray streams was controlled by the degree of superheat of fuel vapor-air mixtures leaded into a cooling section. Diameter measurements of droplets in a spray stream have been done for various spray generation conditions. The mean droplet diameter was constant during a test and the droplet diameter distribution could be controlled to be narrow. Droplets were uniformly dispersed in a laminar spray stream.
