FIELD: power industry.
SUBSTANCE: exhaust gas further processing system for decrease of nitrogen oxide and particle content for internal combustion engines working with air excess. Note that nitrogen oxide neutralisation is done with the aid of SCR-catalyst, and decrease of particle content with the help of dust filter (5, 9) that is installed in the exhaust gas stream of internal combustion engine. Dust filter (5, 9) means surface dust filter or fine cleaning filter that is loaded by SCR-active catalytic material (6, 14) at the rear side. The supply of reducing agent that eliminates nitrogen hydrides or nitrogen hydrides supply is performed upstream relative to dust filter (5, 9).
EFFECT: decrease of particle and nitrogen oxides ejection, minimum structural dimensions of the system.
