摘要

A calculation rule for controlling the thermal performance of cement kilns based on the analysis of gases, characterized by their scales drawn on concentric circles organized in such a way that a circular band, rotating with respect to the other elements, contains in its outer edge a scale and on its inner edge another scale, sliding each of these scales together with the other fixed, when the circular band rotates.
