As part of an ongoing project at the Grand Forks Energy Technology Center to develop a model for fly ash formation during the combustion of low-rank coal, samples of North Dakota lignite were collected and combusted. A chemical analysis of the coal used in the experiments was presented. Fly ash samples were obtained by use of a five-stage multicyclone and were analyzed by scanning electron microscope, x-ray diffraction, and x-ray fluorescence. A chemical analysis of the fly ash samples of each particle size range was given. It was concluded that there was an increase in sodium and sulfur with a decrease in particle size. The experimental results supported the validity of vaporization-condensation mechanisms of particulate formation reported by others.
