The fluidized bed technology is positioned between a fixed bed like a grate furnace where the fuel particles are rather fixed on the grate and an entrained flow where the fuel particles are in a state of pneumatic transport (refer also to Lackner et al. 2010).In fluidized bed technology, the fuel particles are mixed with bed material usually made of …

CBM is produced through a system of fractures in the coal beds that are known as cleats (Figure 2). If the system is entirely coal, as water is removed from the cleat system the reservoir pressure declines and methane is desorbed from the coal into the cleats causing gas production to begin through these cleats (Hower, 2003).
