Abstract
In order to realize energy conservation in thermal power plant，it is the key to reduce fuel oil of coal pulverizer during the start-up and shut-down. Through the sequence control system to the boiler, turbine, generator effective start and stop. The sequence control of start-stop to the mill，And focused on The sequence control logic of start-stop to the mill for the coordination and control unit to provide a reliable guarantee.Mill on the start-up and tripping a logic analyzer, makes operating officer in the course of the operation to reasonably control. Through the mill order to optimize control logic, in the warm mill grinding process, the mill started the process of sequence control, Mills and Mills after the commencement of the order related to the coal sequence control logic Optimized system makes it easier to operate. To avoid the operation staff of the mill export and import control of the shortcomings of bad temperature, reduce the mill very good start and stop fuel, shorten the start-up time;Improve and optimize the mill system in all aspects of the control and regulation, thus greatly accelerating the mill's start-up time, an improvement in fuel savings; Officers can only run through one or a few buttons on the operation of a complete set of equipment and even entire units start and stop tasks. It is generalized the problems of mill in commissioning process and its settlement．
Keywords: coal mill；sequence control；optimized control
