This invention relates to a method and device for regulating a cement burning system to make it more efficient. A product stream, in keeping with customary practice, passes successively through a pre-heating zone, a calcining zone, a sintering zone, and a cooling zone. In accordance with the present invention, the degree of deacidification of the product in the area of the calcining zone is determined by one of several methods and this determination is translated into control signals which control at least one parameter of the method in response to the degree of deacidification.

Method and device for regulating the burning process of a cement burning

Techniques for regulating calcining processes, particularly the calcining of lime containing materials, which are supplied as pulverized raw material, into cement clinkers in a cylindrical rotary koln, provides that the exhaust gas preheats the raw material and the calcined material preheats the combustion air. The quantity of raw material and the quantity of combustible material, the temperature of the combustion air and of the exhaust gas, as well as the composition of the exhaust gas, and additional parameters of the process are continuously measured and partially controlled. From the continuously measured individual values of the process a characteristic value describing the condition of the process, particularly the supply of heat, is formed, and is utilized to regulate the calcining process.
