Scale-up of fluidized bed combustion

Book chapter, 2009

Methods for scaling of fluidized-bed combustors are reviewed. It is found that a general scaling methodology, including simultaneously fluid dynamic and combustion scaling can not be carried out in practical scaling tests. Some kind of simplification is needed. The approach followed here is to differentiate between fluid dynamic scaling, combustion scaling, both related to the basic equations describing the phenomena, and boiler scaling that means scale-up from one boiler size to another, where established design elements can be utilized in the scaling procedure.
