WebThe conversion of the fuel-nitrogen in the coal into NOx did not occur under the reducing atmosphere in the circulating fluidized bed furnace. The final quantity of NOx generated from the combustion in the PCC was formed from gaseous HCN and residual nitrogen in fly ash, which flowed with flue gas from the CFB furnace. WebFormation mechanisms of the fly ash and bottom ash during circulating fluidised bed combustion of a bituminous coal and two solid biomass fuels were studied experimentally. The biomass fuels were forest residue and willow (Salix). The experiments were carried out at full-scale boilers.
