The purpose of this task is to develop and apply instruments to measure the solid feedrate in coal gasification plant gas-solid feedlines, interstage lines, and recycling lines. To date, one of the most promising techniques for mass flow measurements in a solid/gas flow stream is the use of the nonintrusive capacitance sensor. The performance of the capacitance flowmeter (CF) with an improved electrode geometry has been measured experimentally in a gas-entrained 1000 ..mu..m glass bead flow stream at the Argonne National Laboratory (ANL) Solid/Gas Flow Test Facility (SGFTF). The CF measured the solid volume fraction (SVF) and particle velocity and the results were compared with time-of-flight measurements of short-lived radioactive particles. 21 refs., 9 figs.
