Application and Study of kiln temperature control system based on PLC

Kiln is a kind of main heat consuming equipment built with refractory materials to calcine materials and products. The temperature control of kiln directly affects the efficiency of the system, product quality and output. In order to produce the desired product output and quality, the kiln temperature must be controlled within a certain range to meet the process requirements. Due to the uncertainty and large lag of kiln temperature, the traditional control can not guarantee the constant temperature. Now taking the kiln temperature as the research object, the PID control based on PLC controller is adopted for the temperature. The results show that the PID kiln temperature control based on PLC has ideal effect and wide application prospect.
