摘要： PROBLEM TO BE SOLVED: To permit the removal of dust, clogging gas passing holes, through a simple means by a method wherein a honeycomb catalyst, whose gas passing holes are clogged by dust, is dipped into water in a vessel and, thereafter, the vessel is sealed to evacuate and remove the dust in the gas passing holes by passing water therethrough. SOLUTION: A clogged honeycomb type NOx removing catalyst 1 is inserted into a vessel 3, filled with dipping water 4 previously. The rid 5 of the vessel 3 is closed and the vessel 3 is connected to an aspirator 7 through a connecting line 6, then, the aspirator 7 is driven to evacuate continuously for 30min. Thereafter, the aspirator 7 is stopped and the connecting line 6 is separated from the vessel 3 to return the internal pressure of the vessel 3 to an atmospheric pressure, then, the honeycomb type NOx removing catalyst 1 is removed out of the vessel 3. In another case, a supersonic wave oscillator is arranged on the vessel 3 as another method and water is oscillated by shock wave of the oscillator whereby the dust, clogging the catalyst, can be removed.

摘要： PROBLEM TO BE SOLVED: To prevent the increase in the SO2 -oxidation ratio of a denitration catalyst caused by vanadium contained in exhaust gas by keeping the catalyst packing part of a dry exhaust gas denitrizer at the dew point of sulfuric acid or above even when the denitrizer is stopped when fuel of a relatively high vanadium content is used. SOLUTION: Nitrogen oxides in exhaust gas discharged from combustion facilities which use fuel containing 0.5% or more of sulfur components are decomposed and removed by a dry exhaust gas denitrizer 1. In this process, the catalyst packing part 3 of the denitrizer 1 is kept at the dew point of sulfuric acid or above by an electric heater 7, etc., even when the denitrizer 1 is stopped. In this way, since the generation of liquid components and the permeation of vanadium components into the catalyst can be prevented, the increase in the SO2 -oxidation ratio of the catalyst can be prevented.

摘要： PROBLEM TO BE SOLVED: To improve the detecting ratio and precisely and continuously measure NH3 concentration in exhaust gas by providing a sample gas collecting line, a zero gas collecting line and a span gas collecting line each of which is of a vacuum system. SOLUTION: A zero gas (N2 ) is carried through a zero gas inlet 22, and a zero point is set when the zero point by the zero gas is stabilized. After the zero point is set, a span gas (NH3 ) is carried through a span gas inlet 21, and a span value is set when the span value is stabilized. After the span value is set, a sample gas is collected through a sample gas inlet 18. The sample gas flows in the course of the inlet port 18 → a three-way solenoid valve 3 →sample cell 8 → a water trap 11 → a needle valve 121 →a flowmeter 141 →a gas outlet 23. The cell gas collecting line, the span gas collecting line and the sample collecting line are made to be pressure reducing systems, and the pressure within the sample cell is changed by use of NH3 standard gas to measure NH3 concentration.
