Abstract
The invention relates to a method for producing quick lime from lime stone in a continuous regenerative shaft kiln, characterized in that, starting with standard conditions of excessive combustion air for the operation of this kiln, it especially includes a step where the excessive combustion air is progressively reduced until a content greater than 1000 ppm (in volume) of carbon monoxide is reached in the connection flue between the tanks. An increase in the content of gaseous sulphur dioxide is then observed in the gas flue, with respect to a kiln operated in standard conditions.
