Filter for effective elimination of nitrogen oxides and polycyclic aromatic hydrocarbons during combustion of solid fuel in boilers

摘要

Filter for the effective elimination of nitrogen oxides and polycyclic aromatic hydrocarbons in the combustion of solid fuel in boilers is described, consisting of a sorption zone (3) and a sorption-catalytic zone (4), wherein the sorption zone (3) consists of a chemically modified zeolite with sorption properties and the sorption-catalytic zone (4) consists of a chemically modified zeolite with sorption and catalytic properties to reduce the content of hydrocarbons and nitrogen oxides in the escaping flue gas.
