Online monitoring of flying ash carbon content is of important significance for the unit operation and the boiler combustion regulation of a power plant. In the developed flying ash carbon content online monitoring device, a series of technical methods was adopted, which includes the sampling in constant speed, the microwave attenuation method measurement, the purging by pressed air, the ash removal by vibration, the pneumatic ash discharge, the automatic control and so on. The working principle of the device and the structure features of its main components were expounded emphatically and the field application was introduced.
