Circulating Fluidized Bed Combustion of Brown Coal during Mixing Up Biomass

Especially for large CFBC units it is possible to employ only the co-firing of biomass because of logistic problems. So it is interesting to get knowledge about burnout and emission behavior as well as best working parameters to use biomass as co-combustion fuel in already existing units. Therefore the co-combustion of coal/biomass were investigated in bubbling and circulating fluidized beds.
