HIGH-PERFORMANCE LOW-ENERGY ELECTRON GUN FOR DESULFURIZING AND DENITRIFYING FLUE GAS

摘要

The apparatus, which is for desulphurating and/or denitrating flue gases, has at least two large area cathode systems (3a, 3b) arranged in a vacuum casing (6), the casing being provided with electron emission windows of the same length and breadth as the respective cathode systems (3a, 3b). As described, each window has a frame 1 and a titanium sheet (9) supported by bridge elements (8, Figs. 4 and 5). The frame (1) may be water cooled. The bridge elements may also have water cooling channels or may be of solid construction. IMAGE
