Abstract: The automatic startup and shutdown technology for coal-pulverizing system is the prerequisite for fully automated combustion control . In this paper, the startup and shutdown timing and sequence of coal-pulverizing system was studied, and then the corresponding expert knowledge base for coal-pulverizing system was established to automatically optimize its timing and sequence. and hence the intelligent full-process control was set up for the coal-pulverizing system during unit startup and shutdown operations. The sequential procedures of startup and shutdown process for double inlet and outlet tube mills was also designed. In this way the complete automatic process control for the coal-pulverizing system was realized. The application practice shows that the expert knowledge based automatic startup and shutdown technology for the double inlet and outlet tube mills can meet the needs of the fully intelligent control for combustion , which has greatly improved the automation level and operation stability of the plant.

Key words: expert knowledge base, inference rules, double inlet and outlet tube mills, startup and shutdown
