Description

Verfahren zum Brennen oder Sintern von Kalkstein oder sonstigen Karbonaten in gasbeheizten Öfen Der Gegenstand des Hauptpatents ist ein Verfahren zum Brennen von Kalkstein in einem gasbeheizten Schachtofen, wobei Abgas von hoher Temperatur aus dem oberen Teil des Ofens abgezogen, mit kühlerem Brenngas gemischt und anschließend von einem Gebläse wieder in den Ofen zurückgeführt wird: Der Erfinder hat erkannt, -daß es vorteilhaft ist, als Brenngas Schwelgas -aus dem Schwelaufsatz eines Gaserzeugers zu verwenden, weil dann nicht das gesamte im Generator erzeugte Gas, sondern nur das anfallende kalte Schwelgas mit dem heißen Abgas gemischt zu werden braucht. Das Verhältnis Abgas zum brennbaren Gas kann bei Verwendung von kaltem Schwelgas wesentlich erhöht werden. Das Klargas des Gaserzeugers wird durch eine Leitung unmittelbar in den Ofen gefördert, ohne durch das Umwälzgebläse hindurchgeleitet zu werden. Wenn die Temperatur des Klargases höher ist als die Temperatur des Mischgases, das durch das Umwälzgebläse gefördert wird., wird eine höhere Ofenleistung und ein noch milderes Kalk !brennen erreicht.Process for burning or sintering limestone or other carbonates in gas-fired ovens The subject of the main patent is a method of burning of limestone in a gas-fired shaft furnace, with exhaust gas of high temperature withdrawn from the upper part of the furnace, mixed with cooler fuel gas and then is fed back into the furnace by a fan: the inventor has recognized -that it is advantageous to use carbonization gas as the fuel gas -from the carbonization attachment of a gas generator to use, because then not all of the gas produced in the generator, but only the resulting cold carbonization gas needs to be mixed with the hot exhaust gas. The ratio of exhaust gas to combustible gas can be reduced when using cold carbonisation gas can be increased significantly. The clear gas from the gas generator is supplied directly through a pipe conveyed into the furnace without being passed through the circulation fan. If the temperature of the clear gas is higher than the temperature of the mixed gas, the is promoted by the circulation fan., a higher furnace output and an even more milder lime! burning achieved.
