ZHONG Ji-sheng 1,CHEN Da-xi 2,ZHANG Li-hua 3 (1.Liaoning Petro-chemical Univ. Fushun 113001, Chian;2.Changlin g Refinery, Yueyang 414002, China; 3.Cangzhou Refinery, Cangzhou 061000, Ch ina)  
The paper introduces a partial research result of a project that is "The Investigation of evolution and diagnosis using infrared h eat picture for high temperature furnace tubes on Iine",which is rewarded proje ct.The research result show the inspection of heating fumace tubes on line can b e operated through view window using Infrared heat picture,If using high tempera ture flame filter and wide angle lenses and heat insulation cover like PM350 typ e Infrared heat picture instrument.The error-correcting methods by experiment r esearch can improve inspection result of infrared heat picture,It makes the insp ection error between Infrared and thermocouple smaller thea 2%,The application i n the plant showed effective results,This method can satisfy requirement of insp ection for production equipment.
