Design and Implementation of Energy Saving Control and Regulation System for Metallurgical Furnace

This paper from the perspective of saving fuel gas, reasonable design of temperature control system. The thermostat is designed S7-200 series PLC adoption. The communication method of the computer and programmable controller (PLC) temperature control system is described. Software part of the application of the PLC principle to achieve system control. Hardware part of the temperature sensing element thermocouple temperature field, flow meter, fuel flow regulation, adjusting the thermocouple output electrical signal supply line for comparison with the given values, if there is a difference, the difference through the operational amplifier and issued a directive to the actuator, the actuator to perform the task. The simulation interface of the application configuration, virtual reality condition, the master-slave real-time monitoring system composed of computer and PLC to give full play to the their respective advantages in the industrial control, realize the decentralized control and centralized monitoring and other new features. Write part of the program, to research on energy efficient and reasonable utilization as the theme, combined with typical furnace, energy for metallurgical furnace the huge energy consumption equipment rational utilization and effective control method is put forward to improve the reasonable design of the program, resulting in applications get effective implementation, for enterprises to save energy, create economic benefits to contribute.
