FLUE GASES CLEANING FROM NITROGEN OXIDES BY ADDITIONAL OXIDATION OF NO TO NO2 AND ABSORPTION
Abstract
Experimental researches of operational characteristics of laboratory samples of two types of packing for the direct contact heat exchanger have been carried out, - Raschig ceramic rings and the developed construction with using the ribbon of amorphous metal alloy. The metal alloy packing slightly surpasses the ceramic one by the basic operational heat engineering parameters, and contributes to oxidation of the NO to water-soluble NO2, which enables to remove more of the latter by absorption with water and, as a result, to reduce the emissions of nitrogen oxides to the environment after contact apparatus by 35 % more efficiently than with using the ceramic packing.
