Simultaneous Reduction of SO2, NOx, and N2O Emissions from
Jun 23, 2000 · The effect of limestone feed during bubbling fluidized bed combustion of coal on emissions of SO2, NOx and N2O was investigated. Two types of bubbling fluidized bed combustors (BFBCs) were employed; One was a conventional single-stage BFBC in which limestone was fed to the bed where coal was burnt, and the other was a two-stage BFBC in which coal was burnt in the lower bed …
