ABSTRACT:
The invention relates to a method for combusting a dirty and/or difficult to burn fuel in a fluidized bed combustor. The fluidized bed and freeboard zone of the combustor are cooled by a non-intrusive counterflow cooling system which controls combustion temperatures and produces a clean, hot gas. The combustor is operated with many combinations of features including: low, in bed fuel injection; use of finely divided fuel; slug flow fluidization; and injection of lime or limestone to effect desulferization or raise the ash melting temperature, if desired.
