[0002] The endoscopic furnace flame television monitoring device is used to monitor the combustion conditions of the furnace flame. The device is directly extended into the furnace observation hole by the endoscopic optical imaging system. The working conditions on the grate at the initial stage of ignition and the combustion and slagging dynamic conditions on the grate after normal combustion are imaged by the high-temperature peep mirror, and then converted into video signals by the camera and transmitted to the control room via the video cable. The monitor then restores the image to the screen, thereby reflecting all the combustion conditions on the grate. The operating personnel in the control room can observe the combustion conditions on the grate in real time, discover various abnormal conditions in time and take corresponding measures to ensure the safe operation of the boiler. The endoscopic furnace flame television monitoring device generally includes a monitoring component, a corner retreat component, a field control system, a control room control system and a control room display system. The monitoring component includes a high-temperature mirror group, a temperature sensor, a protective tube, a CCD Industrial cameras, high-temperature protective covers, magic tube coolers, etc. are used to capture and transmit flame images inside the furnace. Corner retraction components include electric advance and retreat actuators, electric rotary actuators, mounting brackets, automatic fire-blocking doors and prefabricated pipes, etc., which are mainly used to drive the movement of monitoring components and perform automatic protection functions such as automatic exit of the system due to over-temperature and automatic exit without protective wind. The field control system is the control center of the system, which is used to control the actions of each actuator on-site and the control execution of automatic protection functions. The operation panel has working status display, various alarm displays, control buttons, etc. The control room control system is used for remote control of the system, and the operation method is the same as that on-site.
