Abstract

PURPOSE:To carry out stably and economically the reduction of NOx for a long period of time, by contacting the exhaust gas containing NOx, SOx and O2 with minute drops of a solution of alkali at the spray tower, then treating the exhaust gas with the electric dust collector, thus decreasing the content of SOx in the exhaust gas below the specifiied amount and, after that, by reducing NOx by adding NH3 and passing through the catalyst layer for catalytic reduction.
