Biomass combustion in fluidized bed boilers: Potential

Jan 01, 2009 · Operating parameters of fluidized bed combustion (air staging, excess air, etc.) can be effectively used to reduce PCDD/F emissions . Good combustion practice, minimizing the flue gas residence time in the critical temperature zone (250450 °C), and use of electrostatic precipitator/bag house filter are possible ways to reduce dioxins.
