LOW-TEMPERATURE CATALYTIC REACTOR WITH MOBILE SUBSTRATE FOR CONTROL OF NOx EMISSION IN COAL BURNING

摘要

1. A device comprising:! a combustion chamber for burning fuel that produces flue gas during operation, which may contain a certain amount of NOx, which it is desirable to remove; as well as ! a selective catalytic reduction reactor for recovering at least a portion of the NOx present in said flue gas, said selective catalytic reduction reactor comprising a movable substrate reactor having first and second loops, oppositely directed and spaced apart so that the path the catalyst on the substrate between them was defined as largely vertical; ! characterized in that the flue gas passing through the specified reactor with a movable substrate follows the path of the substrate. ! 2. The device according to claim 1, comprising: said first and second oppositely directed circuits, respectively, a first set of shutters and a second set of shutters, each of these sets having a series of vertically spaced first or second shutters, respectively, with said first and second shutters respectively the first and second set of dampers are deviated from each other, and the trajectory of the catalyst on the substrate is determined between these sets of first and second dampers; ! characterized in that the flue gas passing through the specified reactor with a movable substrate follows the path between the vertically spaced first flaps, moves along the path of the substrate, and then exits between the vertically spaced second flaps. !
