Co-firing of coal and biomass in CFB
Konferensbidrag (offentliggjort, men ej förlagsutgivet), 1999
This is a short review on methods of co-combustion of coal and biofuels or waste in fluidized bed. Four arrangements of co-combustion are shown: in the main combustor, in an additional bed inside of the main combustor, in an additional boiler attached to the main combustor on the water side and in an additional gas generator delivering gas into the main combustor. The importance of fuel properties (ash, alkali, chlorine, trace elements) for design and operation of co-combustion units is pointed out.
