FIELD: process engineering.SUBSTANCE: invention relates to chemistry. Cleaner 1 of cement rotary tube kiln 2 with, at least, one selective catalyst 8 for reduction of nitrogen oxides contained in flue gases, reducing agent feed inlet 16 and with, at least, first and second dust catchers 7, 9. Said catalyst 8 is arranged between said first and second dust catchers 7, 9. First dust catcher is composed of electric precipitator. Flue gases are cleaned by feeding them to first dust catcher 7 composed of electric precipitator, to reducing catalyst 8 and second dust catcher 9.EFFECT: decreased power consumption, longer life.7 cl, 1 dwg |
