This study describes the numerical model of superheated steam drying of lignite from the Belchatow mine in Poland in two aspects: single and multiparticle. The experimental investigation preceded the numerical analysis and provided the necessary data for the preparation and verifiion of the model. Spheres of to 30 mm in diameter were exposed to the drying medium at the temperature ...
Effect of Particle Size Distribution on Rheology of ...
It is believed that by controlling particle size distribution and particle loading coupled with the use of additive chemicals, a coalwater slurry can be economically produced that is compatible with the physical characteristics needed for storage, handling, and burner nozzle atomization. In this study the effect of particle size distribution on the rheology of lignitewater slurries was ...
