Abstract
The apparatus for dedusting a gas by electrostatic precipitation includes an advantageously steel housing and a plurality of discharge electrodes and collecting electrodes arranged in the housing. Each of the electrodes is made of a ceramic material and has an electrically conducting layer on at least one side thereof. The electrically conducting layer consists of a copper, nickel, bronze or iron-chromium-nickel alloy layer having a thickness of 0.1 to 2 mm. The ceramic material has a porosity of 25 to 90%, consists of fibers compacted with an inorganic binder and contains 30 to 70% by weight Al.sub.2 O.sub.3, 15 to 50% by weight SiO.sub.2 and 1 to 10% by weight of the inorganic binder. The discharge and collecting electrodes can be plates with a wall thickness of 5 to 100 mm. The discharge electrodes alternatively are tubular and have a wall thickness of 5 to 30 mm and a diameter of 30 to 100 mm.
