Zusammenfassung:The utility model discloses an on-line measuring device for an unburned carbon in flue dust of a flue, and belongs to the technical field of flue dust detection on a boiler flue. The measuring device comprises a measuring probe and a measuring analytical unit, wherein the measuring analytical unit comprises a laser, a spectrograph and control equipment. The control equipment is connected with the laser and the spectrograph. The measuring probe comprises a shell, a laser focusing module and a spectral signal collecting module. The laser focusing module and the spectral signal collecting module are installed in the shell. The laser focusing module is connected with the laser, and the spectral signal collecting module is connected with the spectrograph. The shell of the measuring probe is opened on the inner wall of the flue. A gas blowing device is arranged at the edge of an opening of the shell and blows gas to form a gas curtain. The focusing areas of the laser focusing module and the spectral signal collecti
