Abstract
Procedure to regulate an installation for the thermal treatment of fine-grained material, preferably raw cement powder, which is equipped with an oven and at least two pre-heating devices mounted in parallel, in which the fine-grained material is heated in direct contact with the hot exhaust gases from the furnace, the exhaust gases from the furnace being driven through the preheating devices with the help of at least one suction current fan, characterized in that, given a quantity of default load for each preheating device, the exhaust gas temperatures are measured behind each preheating device, and because depending on the measured exhaust gas temperatures, the partial amounts of exhaust gases conducted through the pre-heating devices are regulated, preferably automatically, in such a relationship between e yes, that the partial exhaust gas currents do not have any temperature difference between them.
