Fluidized bed combustion: Achievements and problems. Invited Review

Paper i proceeding, 1996

A survey is made of fluidized bed combustion with special emphasis on the behavior of the combustion chamber of an atmospheric circulating fluidized bed combustor. The following subjects are briefly touched: mixing and combustion of fuel, desulfurization, and formation of nitrogen oxides, especially N2O. The general conclusion is that there is much work done concerning fluidized bed combustiion in the form of laboratory studies, but it is uncertain how this information can be translated to the combustion chamber processes, principally because the actual processes occurring in a large-scale combustion chamber are not sufficiently known.
