Design and application research on DCS used for large glass furnace

Large glass furnace is a complex control object with the characters of process complexity and many control parameters. How to improve its integrative control level is the key problem of control system design. A suit of distributed control system used for large glass furnace is presented in this paper. System structure and reliability design methods are issued. The control strategy and system features of this DCS are discussed. OPC technology is presented to interconnect DCS and MIS. The performance results show that the DCS improves outputs and quality of production and integrative control level, realizes integrative control and management, and obtains favorable economic and social benefits.
