NOx AND SO2 EMISSIONS OF HUNGARIAN ELECTRIC POWER PLANT BOILERS

Abstract

Coal fuelled power stations are responsible for about the half of SO2 emission in Hungary. Specific emission values may be 5 to 10 times the ultimate value admitted in the FRG. Introduction of various desulfurization attachment methods has to be endeavoured in coal fired power stations. The share of Hungarian power stations in NOx emission is some lower, about a quarter. The high specific NOx emission attributable to firing methods (construction) is of importance especially for gas firing. Introduction of (primary) firing methods has to be endeavoured, to prevent NOx formation.
