DEVICE AND METHOD FOR TEMPERATURE CONTROL OF CRUSHING PLANT, AND COMPUTER PROGRAM |
摘要 |
PROBLEM TO BE SOLVED: To control a temperature in an outlet of a crusher with high accuracy when shifting from heat-up to milling, in a crushing plant of a vacuum type exhaust gas circulation system.SOLUTION: In heat-up, PID control is performed based on the deviation to the target value of a measured value of a mill outlet temperature. When the heat-up is finished and coaling is started, the flue gas of a constant flow rate (burner load) according to a target value of a process requirement is provided to a hot gas generator 101 to generate hot air until the mill outlet temperature falls to the target value. Then, when the mill outlet temperature falls to the target value, the PID control is reopened based on the deviation to the target value of the measured value of the mill outlet temperature. |
