Filter the effective elimination of the nitrogen oxide concentration and polycyclic aromatic hydrocarbons for combustion of solid fuel in boilers

摘要

Disclosed is a filter to effectively eliminate the content of nitrogen oxides and polycyclic aromatic hydrocarbons in the combustion of fuels in boilers, which consists of the sorbent zone (3) and a sorption-catalytic zone (4), wherein the sorption zone (3) forms a chemically modified zeolite having sorption properties and sorption-catalytic zone (4) consisting of a chemically modified zeolite of sorption and catalytic properties for the reduction of hydrocarbon and nitrogen oxide in exhaust gas escaping
