Analysis and solution to the problem of peeping phenomenon of Double-strength less oil ignition flame detection

Fire detection system is the indispensable part in thermal power generating units. The reliability of oil gun fire inspection plays an important role in improving the reliability and security of the main and auxiliary equipment. The peeping phenomenon which always exists in fire inspection is a difficult problem that affects the safety production of power plants. In this thesis, through analyzing the problems which existed in Double--strength less oil ignition flame detection in Datang Linzhou Co--generation Power Co., Ltd, and a range of factors which affect peeping phenomenon, we proposed the improvement methods, implementation steps and requirements which are adapt to the system of Double--strength less oil ignition flame detection in Datang Linzhou Co-generation Power Co., Ltd. And we estimated the economic benefits which is produced by using the improvement methods, and had done a qualitatively analysis about the unit＇s security and reliability.
