Particle Velocity Measurement of Pulverized Coal flow on a Power Plant Using Electrostatic Sensor Array

Jingyu Zhang, Liguo Tian, Meng Li

Abstract— The particle velocity of pulverized coal in pneumatic conveying pipelines is a key parameter directly related to a higher efficiency and reducing energy consumption of coal-fired power plant. The experiment was conducted on a coal-fired power plant. The cross-correlation velocities between different electrode pairs from electrostatic sensor arrays were presented in this paper. It was found that there was little difference in the particle velocity between the top and bottom areas, which indicated that the stratification flow in the pipeline was not obvious. However the distributions of particle velocities at left and right areas were not uniform. This was due to the influence of the downstream elbow. It can be confirmed that the particle velocities of pulverized coal at different positions in the pipeline are uneven, and a more detailed measurement method need be applied.

Index Terms— electrostatic sensor array, particle velocity measurement, pulverized coal, coal-fired power plant.
