The effects of Solid Fuel Catalyst Additive Ferox by Rennsli on NOx emissions

Today NOX emission can be reduced by primary methods such as retard injection, fuel nozzle modification, change of compression ratio, water direct injection, water emulsification, exhaust gas recirculation (EGR) and secondary method such as selective catalytic reduction (SCR).

The NOx emissions that come from automobiles and other mobile sources contribute about half (50%) of the NOx that is emitted. Electric power plant boilers produce about 20% of the NOx emissions from stationary sources. The rest 30% of the NOx emissions are also added by such anthropogenic sources as industrial boilers, incinerators, gas turbines, reciprocating spark ignition and Diesel engines in stationary sources, iron and steel mills, cement manufacture kilns, glass manufacture, petroleum refineries, and nitric acid manufacture. NOx often appears as a brownish gas.

Nitrogen dioxide is an irritant gas, which at high concentrations causes inflammation of the airways. NOx gases react to form smog and acid rain as well as being central to the formation of fine particles (PM) and ground level ozone, both of which are associated with adverse health effects.

The formation of NOX appears to take place late in the combustion process during the exhaust phase and is influenced by available excess oxygen, high temperatures and time duration.
