Abstract

Группа изобретений относится к смешиванию одного потока текучей среды (F) с большим объемным потоком (2) газа, в частности, для введения восстановителя в дымовой газ, содержащий оксиды азота. Способ смешивания одного потока (F) с большим объемным потоком (2) газа, содержащего оксиды азота, предусматривает натекание потока газа на пластинообразный смесительный элемент (1, 8), установленный под углом относительно потока. Возле него образуются вихри (3) потока, а поток текучей среды подмешивают к объемному потоку газа ниже по течению относительно смесительного элемента. Для лучшего подмешивания потока в большой объемный поток его закручивают. Закрученный поток направляют перпендикулярно поверхности смесител�
