摘要：

Defluidized zones degrade the performance of fluidized beds. Triboelectric currents at the distributor were measured in a variety of gas-solid fluidized beds. A V statistic below 1.5 ms(-0.5) indicated a defluidized zone. This criterion allowed detection of defluidized zones in an industrial bed within 100 ms and is thus suitable for process control.
