Ecological aspects concerning the combustion of lignite in Romanian thermopower plants

Abstract This paper focuses on the analysis of thermopower plants emissions with regard to a new indicator, SONOX (SO from SO 2 and NOX from NO x ), which is symbolized by Σ . Based on this method, analysis is accomplished for several Romanian thermopower plants fuelled by lignite. Conclusions are drawn concerning the possibilities of reduction of the reaction agents for desulphurisation of the flue gas exhausted by the thermopower plants.
