Title: Operating method of waste gas denitrification apparatus
Inventor: WATANABE HIDETOSHI
IPC: B01D53/86
Filed: 1988-12-15
Abstract: PURPOSE:To use a catalyst in the state of the highest efficiency of denitrification regardless of the presence of uncertain elements such as catalyst deteriorating soot, etc., by judging the state of deterioration of a catalyst and denitrification performance according to injection amount of NH3 and raising the temperature of a waste gas at the inlet of the catalyst stepwise. CONSTITUTION:As a catalyst 4 is deteriorated, the inject ion amount of NH3 from an NH3 spraying nozzle 6 is increased so as to keep the denitrification efficiency of said apparatus 3 higher than a prescribed value and then when the injection amount of NH3 becomes more than or equal to a prescribed value, the temperature of the waste gas at the inlet of the catalyst 4 is raised by a heater 2 and the injection amount of NH3 is decreased and again the injection amount of NH3 is increased as the catalyst 4 is deteriorated again. Like this, when the injection amount of NH3 reaches the prescribed value, the temperature of the waste gas at the inlet of the catalyst 4 is raised stepwise so as to keep said denitrification efficiency within a prescribed value. As a result, the catalyst can be used in the state of highest efficiency regardless of uncertain elements such as catalyst deteriorating soot, etc., thereby the service life of the catalyst can be lengthened remarkably.

Abstract: PROBLEM TO BE SOLVED: To easily preserve a calling card and to eliminate necessity of newly delivering the card by making a postcard with a calling card having a perforated line drawn for indicating an edge of the card becoming the card in the cut-out state. SOLUTION: Perforated lines 11 indicating adjacent two sides of a calling card are drawn at a lower left corner of a surface of a government-printed postcard 10 to become the same size as the card. A calling card part 12 to become the card in the cut-out state is obtained by the lines 11 and the edges of the lower left corner of the postcard. Accordingly, even if the postcard in which the part 12 is cut out is, for example, discarded, the card is retained at the other party. Since the other party can preserve it in the same calling card container as normal calling card, the preservation is easy. Further, an impression is retained by a deed of cutting out the card. Particularly, in a greeting card such as a notice of change of address, it is not necessary to newly deliver the card to the other party.  Since the lower left corner becomes the card, the lines 11 may be sufficient only at the two sides.
