Original abstract
This paper deals with elimination of nitrogen oxides (NOx) by using the so called catalytic filtration method of selective catalytic reduction (SCR). Series of experimental tests of NOx reduction was conducted in MSW (municipal solid waste) incineration plant. Various operational conditions were involved and assessment of deNOx (removal of NOx) technology was carried out. Two samples of filtration material were later subjected to analysis and evaluated due to decrease of their efficiency during experimental tests under nonstandard conditions (especially for over-stoichiometric ratios NH3 (ammonia) : NO (nitric oxide) higher than 1.1 mol/mol). Catalytic filtration was also compared to other common deNOx methods. This comparison was based on deNOx efficiency of particular methods and their investment and operational costs.
Czech abstract
Tento článek se zabývá zneškodňováním oxidů dusíku (NOx) pomocí tzv. katalytické filtrace metodou selektivní katalytické redukce (SCR). Byla provedena série experimentálních testů snižování NOx na spalovně komunálního odpadu při různých provozních podmínkách s vyhodnocením účinnosti této technologie pro odstraňování NOx (deNOx). Následně byla provedena analýza dvou vzorků filtračního materiálu a vyhodnoceny příčiny poklesu účinnosti během experimentálních testů za nestandardních podmínek (zejména s přebytkem NH3 : NO vyšším než 1.1 mol/mol). V neposlední řadě byla katalytické filtrace porovnána s ostatními běžně používanými metodami pro snižování obsahu NOx. Toto porovnání bylo provedeno na základě dosažitelné účinnosti deNOx a vyhodnocení investičních a provozních nákladů.
