Process to adapt a tunnel furnace to various performances, and a calculator-controlled tunnel furnace

摘要

In order to adapt a tunnel furnace of the ceramics industry to various performances and combustion curves, two or more desired value sets (combustion curves 11, 12) of the tunnel furnace (1), at different furnace performances lying as far as possible from one another, are empirically established and stored in a process control computer. The desired values which apply for all other performances of the tunnel furnace are also established in the process control computer by regression and the material flows are controlled via the regulators of the tunnel furnace depending upon the performance required. In this manner it is possible to achieve, with low identification and computer expenditure, an extensive adaptation of the tunnel furnace to different operating states. The control of the tunnel furnace is thus carried out depending upon the feed rate of the material to be burned and its quality, so that optimum adaptation can always be achieved. IMAGE
