Abstract: Design and application of a multifunctional automatic burning system with automatic protection function for safety production are introduced. Constitution and configuration of the burning system are described .Its functions, method and subroutine are presented. Avoiding the defects of manual mode, PLC as the core of control system and a man-machine interface as surveillance and control center carry out combustion process, security detection and automation of prevention of dangerous. Closed-loop control systems composed of PID, Frequency Converter, fuel control valve block and online monitoring sensor, can accurately control fuel burning, gas burning and mixed burning which are composed of oil and gas.
Key words: PLC, burning system, safety detection
