Patent DE-4326835-A1 (DE)
Inventor: KURZ HANS-JOACHIM
IPC: B41F31/00
Filed: 1993-08-10
Abstract: The cooling system for cylinders of printing machines comprises at least one compressed-air line (18) having at least one compressed-air opening (20) for blowing cold air against a cylinder (6) to be cooled. At least one recirculation loop (30, 32, 34, 36, 28) is provided, which is separate from the cold air of the compressed-air line (18), sucks off air blown onto the cylinder from the compressed-air opening (20) by means of a fan (28) contained in the recirculation loop, and blows it back onto the cylinder (6) parallel to the cold air. As a result, the temperature of the cold air (22) can be effective on the cylinder (6) without the temperature previously having been changed. The cold air deflected by the cylinder is fed back onto the cylinder (6) for additional cooling. <IMAGE>

Title: Method and device for burning carbonisation gases
Inventor: BRAUN SIEGFRIED
IPC: F27B9/26
Filed: 1993-09-03
Abstract: Carbonisation gases, which, within a firing channel of a furnace, are driven out of firing goods moved, preferably continuously, through the firing channel, are extracted from the firing channel and burnt in a combustion chamber with an additional supply of air. At least some of the combustion gases formed during this process is fed back into the firing channel to heat the firing goods. The carbonisation gases are sucked out of the firing channel into the combustion chamber by a partial vacuum generated during the outflow of a gaseous medium into the combustion chamber. The combustion air or a mixture of combustion air and a combustible gaseous medium can be injected into the combustion chamber. The mixture is ignited as it enters the combustion chamber. The temperature and/or quantity of the combustion gases returned to the firing channel is/are controlled as a function of the temperature of the combustion gases and/or the temperature in the firing channel. The combustion gases are fed to the firing channel in a final firing zone which extends over at most one quarter of the total length of the firing channel. The combustion gases are guided through the final firing zone to an exhaust flue in each case arranged at the end of the final firing zone. After emerging from the firing channel, they are subjected to reoxidation. The combustion chamber of the associated device has at least one inlet opening for a gaseous medium, which is arranged in such a way that ... Original abstract incomplete.
