Fluidized bed combustion: mixing and pollutant limitation

Bo Leckner (Institutionen för energiomvandling)
1st European Symposium on Fluidized beds in energy production, chemical and process engineering and ecology Vol. 2 (1998), p. 39-64.
[Konferensbidrag, övrigt]

Despite the lack of published information, this review concentrates on processes in large circulating fluidized bed combustors, and especially on mixing between fuel and air. Largeconcentration differences may be present in the combustion chamber, but the concentration cannot be properly predicted. Mixing is important for combustion but also for sulphur capture through the formation of reducing zones. This and other factors influencing sulphur capture are discussed. Measurement of gas concentration in a CFB combustion chamber are shown, and various methods to reduce the emissions of N2O emission are presented.

Nyckelord: Fluidized bed combustion; Boiler; Emissions; SO2, N2O


Invited lecture. The conference took place in Ohrid, Macedonia 1997.
