  • To investigate the influences of ammonium sulfate(AS) on the K/S/Cl transformation and N2O/NO emission, the biomass and semi-coke were co-combusted in a 50 kW circulating fluidized bed under O2/CO2 atmosphere. The experimental results show that AS can reduce the Cl content in deposits obviously and decrease the NO concentration in flue gas significantly. Besides, AS can retain more K in bottom ash and circulating ash, thereby reducing the K content in deposits. In terms of reducing Cl in deposits, the top half of the riser is the optimal position to inject AS.
