      Chapter5 Combustion Systems for Solid Fossil Fuels

      In a grate firing system, the solid fuel lies in a bulk bed on a moving grate. The fuel burns with the combustion air which is blown through the grate bars and through the bulk. At low flow velocities, single coarse coal particles with sizes up to 30mm (approximately the size of a nut) remain in the coal layer on the grate.
