... Engineering (now Alstom Power) typically set the design velocity in the range of 12 to 18 m/s (40 to 60 ft/s) ( Ref 5 ). Lower velocities would be used for a boiler burning coals that yield heavy loading of erosive ash, which is usually indicated by high silica content ( Ref 5 ). For fluidized-bed coal-fired...

... shows carbon steel heat-transfer tubes in a fluidized-bed combustor. The tubes have been polished through the action of particles of sand impacting at a velocity of approximately 1.8 m/s (6 ft/s). The black appearance of these tubes is due to the oxide scale, which has been polished (that is, thinned...

... to size. Metals and glass are typically removed from RDF fuel prior to combustion. Thus, RDF fuel has a higher heating value than that of a mass-burning unit. A small number of boilers in use today are based on the fluidized-bed technology. The mass-burning unit uses a mechanical stoker to feed the fuel...
