Solid Mass Flux Measurement of the Gas-Solid Flow Using the Elbow-Ultrasonic

Solid mass flux measurement method of the gas-solid flow by the Elbow-Ultrasonic is brought out in this paper, it basedon the elbow solid mass flux measurement method and the Ultrasonic velocity measurement method. The novel methodneednot pre-required knowledge about the gas-solid flow density. The experiment system is built and experiments by mixing the coal powder with gas as test material are performed on the 80 mm test facility. The accuracy is studied by comparing the flow measured by Elbow-Ultrasonic with it by weighbridge. The experiment results prove that this method is feasible.
