The  power plant Gap system air pipe  GJCFL-15 is used for measuring the sealing gap of the air preheater, and the key issue in the control system is the measurement of the deformation of the preheater. The difficulty lies in the fact that the deformed preheater rotor is moving and the temperature inside the air preheater is close to 400 ℃, while there is also a large amount of coal ash and corrosive gas inside. It is very difficult to detect the displacement of moving objects in such harsh environments.
