Abstract

PURPOSE: To continuously operate this process over a long period while fixedly keeping the desired denitration coefficient continually, in an operation method of this exhaust gas denitration process for making notrogen oxides in exhaust gas harmless by means of an ammonia catalytic reduction method.
CONSTITUTION: This process is operated in order to reduction remove notrogen oxides in such a manner that ammonia from an ammonia supply source U is introduced to an exhaust gas drawing line α joining a generating source P of exhaust gas, in which the concentration of nitrogen oxides contained, the quantity of gas generated and/or the temperature of gas generated change, and an exhaust gas denitration device Q through a control valve a4 controlled in response to the output of a computing element a3, to which signals from a nitrogen oxide concentration measuring meter a1, an exhaust gas flow-rate measuring meter a2, an exhaust gas temperature meansuring meter a5, etc. are input, and a line ω. When no reaching to the desired denitration coefficient is detected by means of a measuring meter Z in a discharge line β, an IN-LINE heater R is operated, and catalysts, which lose their activity, in the denitration device Q are regenerated.
