An emission electrode system for electro-filters, a system which has a rectangular frame having parallel emission electrodes (6) strung between its upper (1) and lower parts and/or transverse stiffeners (4). The frame is made from tubing having a rectangular, oval, or other cross section, the height (h) of the tubing cross-section being greater than its width (l), in order to stiffen the emission electrode system in the longitudinal direction, without increasing its thickness. Furthermore, at one end of the emission electrode (6) there is fitted a spring member (10) and a tightening member (11) for keeping the emission electrode taut in spite of the different thermal longitudinal expansion of the emission electrode and the frame. <IMAGE> |
