Abstract (en)
[origin: EP0526392A1] The device for mixing in a small amount of fluid (1) into the main stream of another fluid (2) in a main duct has a nozzle injection system (3) and a static mixing element (4, 5) downstream thereof. The input cross section (F) of the mixing element is subdivided into subareas (F1, F2, F3, F4). The nozzle injection system comprises metering main pipes having a plurality of directed metering orifices (21). The flow rates through the metering orifices are proportional to the part streams through the corresponding associated subareas (F1, F2, F3, F4). This results in very uniform through-mixing over a short distance and with only a small pressure drop. The mixing-in device is particularly suitable for Denox installations. <IMAGE>
