It has been demonstrated that unaugmented, unconfined, premixed coal dust-air flames can be stabilized on small conical or flat, Meeker type burners. Since these flames are laminar, they can be used to study the kinetics of various processes in coal combustion and related areas such as understanding mechanisms of fireside corrosion and of flame and explosive inhibition. Some of the current work with these flames is directed toward identification and measurement of minor alkali metal and other species responsible for fireside corrosion. In order to make these measurements, molecular beam mass spectrometric sampling techniques have been adpated for use with these heterogeneous flames. In this paper, the equipment and techniques used are reviewed and some preliminary results presented.
