Scale-up of fluidized-bed combustion – A review

Artikel i vetenskaplig tidskrift, 2011

Methods for scaling of fluidized-bed combustors are reviewed. It is found that a general scaling methodology, including simultaneously fluid-dynamic and combustion scaling, cannot be applied in practical scaling tests. Simplifications are 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.
