MEASUREMENT OF VELOCITY AND CONCENTRATION OF PARTICLES IN CFB BY MEANS OF A NOVEL TELEMETRIC PROBE

摘要

A modern non-invasive optical measuring system, based on detection of light reflected from the suspended particles, has been developed to measure local solids concentration and velocity in gas-solid two-phase flow. As the sensor of reflected light a novel photodiode line has been used. This sensor was employed successfully in series of measurements performed in a circulating fluidized bed cold reactor.
