になると共に、脱硝反応が遅く脱硝効率が低い。2. Description of the Related Art A denitration system (removal of nitrogen oxides in a gas) is a wet denitration method using a denitration agent in a spray tower or a spray filling tower, or an ammonia catalytic reduction in which exhaust gas is dried (dry). There is a dry denitration method such as the method. Since the denitration agent is expensive in the wet denitration method, the running cost is high, and the denitration reaction is slow and the denitration efficiency is low.

は不可能であった。Therefore, as the denitration method for general combustion exhaust gas such as boiler exhaust gas, the ammonia catalytic reduction method denitration system which uses inexpensive ammonia and exhibits high denitration efficiency is most often adopted. However, in the exhaust gas of a glass melting furnace or the like, the catalyst in the ammonia denitration tower loses its catalytic function in a short period of time due to the influence of Na, K and compounds thereof in the exhaust gas, so-called catalyst deactivation occurs. Denitration was impossible.

Despite being a high concentration of several hundreds PPM, it was not possible to take sufficient measures. Since ammonia method denitration is carried out at a high temperature of around 300 ° C., a method of denitration without cooling the high temperature of the exhaust gas such as a glass melting furnace by previously removing dust with a dry dust removing device is also considered. Since the harmful substances such as K, which are harmful to the catalyst, are vaporized or fine particles, dust cannot be prevented, the ammonia denitration catalyst is adversely affected, and the denitration effect deteriorates within a short period of time, and the denitration device is not perfect.
