Abstract
1. Process for the thermal cleaning of ring furnace exhaust gases for the burning and annealing of carbon materials, which ring furnaces are using several successively running fires, wherein at least part of the exhaust gases conducted to the exhaust gas flue after having brought in heat exchange within the pre-heating chambers where they have become enriched with effluent particles and smouldering materials originating from the furnace process, are returned into the last closed cooling chambers of the fires and another part of the exhaust gases are mixed to the primary air, and wherein the exhaust gases are pressed into the exhaust gas flue by a flue-van within the smoke-flue, characterized in that the carrying air necessary for the heat transport corresponding also to the secondary air for the combustion of the fuel and the vapors of the pyrolysis is sucked-in by controllable vans (Vu ) positioned behind the last lids (D5) of the fires, blown into the smoke-fuel (2, 2') connected thereto and introduced through pipes (3) arranged between the smoke-fuel (2, 2') and the cooling chambers (4) into the fires, so that by the sealing of the cartridges of the respective first opened chamber of a fire by means of a cover frame uncontrollably entering of air is avoided and the vacuum necessary for the furnace area and produced by the flue-vent (Vk ) and controllable traps (7) is controlled within the smoke-flues (2, 2').
