SOMMARIO

Lo scopo del presente lavoro consiste nell’esaminare le tecnologie per l’abbattimento delle emissioni inquinanti prodotte da impianti di generazione termoelettrica. Nella prima parte vengono esposte e definite le migliori tecnologie disponibili elencate per tipologia di combustibile utilizzato, con riferimento ai valori limite di emissione indicativi. Nella seconda parte sono state trattate le tecnologie emergenti per alcuni dei combustibili citati, riportando le tecniche per la riduzione degli inquinanti maggiormente significativi, in particolare sono indicate le misure primarie, secondarie e le tecniche combinate per la riduzione delle emissione di ossidi di zolfo e degli ossidi di azoto e le tecniche di riduzione delle polveri. Nella terza parte è stata trattata l’applicabilità delle tecniche descritte agli impianti esistenti con un’analisi di fattibilità economica costi-benefici.

ABSTRACT

The purpose of this paper is to examine the technologies for reduction of pollutant emissions from thermoelectric plants. In the first part are exposed and defined the best available technologies listed by type of fuel used, with reference to the emission limit values indicative. In the second part have been treated emerging technologies for some of the fuels mentioned, reporting techniques for the reduction of pollutants most significant, in particular the measures are: primary, secondary and combined techniques for the reduction of emissions of oxides of sulfur and nitrogen oxides and reduction techniques of the dust. In the third part was treated the applicability of the techniques described to existing plants with an analysis of economic feasibility costs and benefits.
