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.
摘要翻译：用于还原烟气管道内的烟气中的氮氧化物的装置和方法包括用于将还原剂注入管道内的烟道气中的多个分配管。每个分配器管包括一个控制阀，以便能够设定合适的还原剂的注入，以响应烟道气中的氮氧化物在烟道气管道的横截面上的不同浓度。每个分配器管包括至少两个平行的分配器管段，其从烟道气管道的相对侧延伸到烟气管道的中心。两个平行的分配管段包括沿其长度的多个开口，以在整个横截面的整个对齐部分中大致均匀地供给还原剂。使用控制阀来调节还原剂以提供适当的量，这对应于在整个横截面的每个对应部分处的烟道气中氮氧化物的特定浓度。

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 process for the removal of nitrogen oxides and soot from exhaust gases from machines and combustion installations burning heavy fuel oil by means of free-passage catalysts at increased temperatures with the addition of ammonia into the exhaust gas stream ahead of the catalysts. To make the process mre effective, the soot adhering to the catalyst surfaces is removed by burning it off and/or by friction resulting from the admixture of sand, ash or similar abrasive mixtures into the exhaust gas stream ahead of the catalysts.

摘要： In a process for the reactivation of a catalyst, which is used for the removal of NO.sub.x, oxides of nitrogen, from exhaust gases, the catalyst should be capable of easy reactivation. For this purpose, when the catalyst starts to lose its activity, it is exposed in a reducing atmosphere to a carbon monoxide current. In an apparatus for the execution of the process, the catalyst is placed in two separate chambers. The carbon monoxide stream is directed alternately to both chambers.

摘要： A heat exchanger and especially a blast preheater (or cowper) for blast furnaces with refractory lining, insulating layer and steel jacket is described, the insulating layer of which is designed so that a steel jacket temperature of from 20.degree. to 60.degree. C. can be set and that said steel jacket is made of chromeless structural steel having a molybdenum content in the range from 0.01 to 2% by weight. The blast preheater (or cowper) has a prolonged service life and a low tendency to nitrate tension crack corrosion of the jacket sheet, for which reason it is very suitable for use in a process for the temperature control of gas and blast for the blast furnace. The process is suitable for blast preheaters (or cowpers) with external or internal combustion chamber or checker chamber and downstream collector ducts.
