    摘要: The pulverized coal burner suitable for lowering the concentration of nitrogen comprises a pulverized coal nozzle (10) for jetting a mixture of pulverized coal and primary air, a secondary air nozzle (11) and a tertiary air nozzle (12), concentrically arranged around the outer periphery of the pulverized coal nozzle (10), and a tube expanded portion (20) at the end of a partition wall separating two adjacent air nozzles. A flow shift means for shifting the secondary air in the secondary air nozzle so as to flow along the tube expanded portion, for example a guide plate (61), is provided. The secondary air comes to be jetted outward by the guide plate, and mixing of the secondary air and the tertiary air with pulverized coals is delayed, whereby an amount of occurrence of NOx can be decreased. The guide plate (61) is a ring disposed in an outlet region of the secondary air nozzle (11), which ring has a taper-shaped ring portion for guiding a part of the secondary air (52) in a radially outward direction.

    摘要: A denitration catalyst for use in the reduction of nitrogen oxides contained in an exhaust gas containing highly deliquescent salts as dust with ammonia, which bears thereon a porous coating of a water-repellent organic resin, a porous coating of a mixture of a water-repellent organic resin with inorganic oxide particles, or a porous coating of a mixture of a water-repellent organic resin with catalyst component particles. The denitration catalyst can be prepared, for example, by coating the surface of a denitration catalyst with an aqueous dispersion containing a water-repellent organic resin having a lower concentration, drying the coating, further coating the dried coating with an aqueous dispersion containing a water-repellent organic resin having a higher concentration, and the drying the coating to form a porous coating of a water-repellent organic resin. This denitration catalyst, even when used in the treatment of an exhaust gas containing ash containing highly deliquescent salts, enables the water-repellent porous coating formed on the surface to prevent the salts that have deliquesced from entering the catalyst. This can prevent the deterioration of the catalyst and enables a high catalytic activity to be maintained for a long period of time.

    摘要: The invention is directed to providing a catalyst having higher mercury oxidation performance than a conventional catalyst without increasing catalyst quantity or enhancing SO 2 oxidation performance and constitutes an oxidation catalyst for metal mercury, which contains a molybdenum and vanadium complex oxide, for example, MoV 2 O 8 , as a main component having a catalytic activity and which is formed by placing the molybdenum and vanadium complex oxide in layers only on the surface of a plate-like or honeycomb-like porous carrier. The porous carrier contains Ti and W and has a function of an NOx removal catalyst as a whole.
