Abstract
Both premixed and diffusion laminar propane-air flames have been burnt in a controlled environment with respect to humidity and particle concentration. A Condensation Nuclei Counter and Whitby Aerosol Analyzer were used to determine the concentration and size distributions of the resulting aerosols. The most important parameter controlling the production of particles by this system was found to be the humidity ratio in the system above the flame. Other parameters such as total fuel flowrate and oxidation ratio were found to be of secondary importance. Experiments comparing aerosols produced by flames burning in filtered and unfiltered air indicate that a synergistic effect exists, resulting in the production of many more fine particles as well as about a 50% increase in the total aerosol volume in the case of the flame burning in unfiltered air.
