The method has the advantages that the flow speed and the concentration of the pulverized coal are accurately measured and monitored, and the method has important significance and value for realizing the online leveling of the boiler air and the pulverized coal and improving the economy and the safety of the boiler operation. Due to friction between the pulverized coal particles and the conveying air, and impact between the particles and the pipeline wall, the pulverized coal carries a certain amount of electrostatic charges. When a large number of pulverized coal particles pass through the metal electrode, a certain amount of induced charges appear on the surface of the electrode, and an electrostatic signal is detected through a specially-designed-in-shape circuit. The random current signal sensed by the electrostatic induction electrode is firstly conditioned through links such as amplification and filtering of a front-end circuit, and then the sampled digital signal is subjected to a series of processing such as correlation operation in a digital signal processor so as to obtain characteristic parameters of the fluid. Based on the above principle, this document proposes a coal pulverizer pulverized coal pipeline monitoring device.
