Abstract: As the key equipment of petrochemical industry, the safe and stable operation of industrial furnaces plays a decisive role in the efficient and sustainable development of petrochemical enterprises. How to ensure the safety and stability of industrial furnaces is the common goal pursued by major refining and chemical companies. The furnace combustion monitoring methods mainly include ion rod flame monitoring, optical flame monitoring and industrial television. And the control system involves automatic leak test of valve, furnace purging, pilot ignition (including ion rod flame monitoring), main flame ignition (including optical flame monitoring) and air-fuel ratio control. The comprehensive promotion of the application of furnace combustion monitoring and control system will fundamentally improve the operation safety and stability of industrial furnaces and eliminate the risks of explosion in industrial furnaces under the conditions of start-up, shut-down and fuel instability.

Key words: industrial furnace, safety, stability, combustion monitoring
