Atmospheric (non-circulating) fluidized bed (FB) combustion

Kapitel i bok, 2013

This chapter describes fluidized bed boilers, particularly of the non-circulating type, called bubbling fluidized bed boiler. This type of boiler is predominantly used to burn biomass and waste fuels. First, some principles of performance are given, explaining the difference between circulating and non-circulating designs, then examples of boilers are shown. Finally, the most important restriction in using fluidized bed combustion for some biomasses, bed sintering and deposits, is discussed and indications are presented on current efforts in finding ways to mitigate this problem.
