In this process, the air and steam flow required for gasification is sufficient to fluidize the bed of coal, char and ash. Fluidization occurs when the gasflow velocity lifts the particles and causes the gassolid mixture to flow like a fluid (Shadle et al., 2002; Crelling et al., 2005). Entrainedflow

Coal preparation is a stage in the coal supply chain that follows mining but precedes shipment to the final end user. For many operations, runofmine coal consists of a composite mixture of carboniferous material and various noncoal impurities, such as rock, shale, clay, and water. Coal preparation, also denoted washing, cleaning, processing ...
