Abstract

Operational experience with the automatic control system for the desulfurization of coke-oven gas at OAO Magnitogorskii Metallurgicheskii Kombinat is considered. This system was designed by Krupp-Koppers. Problems with the control system are analyzed—in particular, problems typical of control systems with feedback and photometric instruments. In practice, perturbation-based automatic control systems are more likely to ensure reliable and stable operation of the desulfurization system, if the operator periodically corrects the parameters in the control algorithm on the basis of independent monitoring of the process.
