摘要： Apparatus and method for reducing nitrogen oxides in flue gas within a flue gas duct includes a number of distributor tubes for the injection of a reducing agent into the flue gas within the duct. Each distributor tube includes a control valve to be able to set an appropriate injection of the reducing agent to respond to different concentrations of the nitrogen oxides within the flue gas over the cross section of the flue gas duct. Each distributor tube comprises at least two parallel distributor tube segments which extend from opposite sides of the flue gas duct to the center of the flue gas duct. The two parallel distribution tube segments include a plurality of openings along the lengths thereof to supply the reducing agent generally evenly throughout their aligned portions of the cross section. The control valve is employed to adjust the reducing agent to provide the proper quantity thereof which corresponds to the particular concentration of nitrogen oxides within the flue gas at each corresponding portion of the entire cross section.

摘要： This invention relates to a process for the manufacture of catalysts for the reduction of oxides of nitrogen from exhaust gases and in chemical air cleaning processes in which a catalytically active material containing iron ores, chromium ores and/or zeolite is placed in contact with a carrier means having a series of openings; e.g., wire mesh, expanded or perforated metal or any type of grid-like structure to form a catalytic member. The carrier means is etched with an acid etchant before forming the catalytic member or, instead, the catalytic member is etched with an acid etchant. The catalytic member is bonded by a thermal treatment; e.g., drying, tempering and/or fixing. This invention also relates to catalytic members or products produced by the process. This invention proposes the use of pressure bonding to obtain a catalytic member product which has significantly improved catalytic activity, greater mechanical strength and higher resistance to chipping.

摘要： A catalyst for use in a process for the removal of nitrogen oxides from exhaust gases contaminated with dust in which the process uses ammonia. The catalyst is made of a material which is easily disposable. Furthermore, the catalyst should be completely used up in the catalysis. The catalyst comprises individual ceramic bricks with a porous surface, and passages therethrough for the flow of the exhaust gases. The bricks exhibit a resistance to abrasion which is designed so that the dust of the exhaust gas which flows through the passages erodes the catalyst surface, thereby reactivating the catalyst. The exhaust gas carries the dust and the eroded material along with it.

摘要： In the process of transferring coke from a coke oven chamber in a battery of coke ovens to a quenching car, the coke is quenched by a water spray from above. The resulting steam is collected in a hood located above and movable with the quenching car and is either exhausted from the hood and conveyed to a condenser or is condensed in the hood with the condensate being collected, cooled and recirculated to provide the water for the quenching and condensing sprays. The apparatus and method of this invention provides for transferring and quenching the coke without emitting harmful gases and dust to the atmosphere.
