Influence of Changes in Physical Parameters of Fluidized Beds on Its Characteristics of Presssure Fluctuations

Abstract

Fluctuation characteristics are effective tools for determination of the type and state of fluidization during the operation of a fluid layer. They are based on monitoring and processing of fluctuation spectra of a gas in which a solid is fluidized. A method of evaluation of changes in operation parameters of the layers during a long operation of a fluid device, based on assessment of changes in corresponding fluctuation characteristics is proposed.
