Abstract: In order to understand the operation problems of flame detection systems, exchange the troubleshooting experiences, and explore the measures to improve the system operation reliability, the survey on the operation of furnace flame detection system in power plants is conducted and summarized by the Thermodynamic Automation Technical Committee of Power Industry. Through comparison of the performance, technical characteristics and practical application reliabilities of different flame detection systems it is concluded that the split flame detection system outperforms the integrated flame detection system. After the discussions on the solutions to the detected problems, cautions on flame detection system maintenance are issued. Finally, suggestions on the topics for further studies are put forward for reference.

Key words: thermal power plant, boiler, furnace, flame detection system, performance, reliability, comparative analysis, control logic
