Title Quantitative evaluation of electrostatic charges in fluidised-bed equipment
Original title Količestvennaja ocenka ėlektrizacii psevdoožižennogo sloja [in Russian]
Bibliographic information Apr. 1980, No.4, p.45-47. Illus. 9 ref.
Abstract The accumulation of static electricity charges in a fluidised bed may ignite matter in suspension in the bed. An equation is presented which enables the electrostatic potential to be evaluated, taking into account: particle dimension; fluidising gas flowrate; dielectric constants of the materials of which the enclosure is constructed, and those of the fluidised matter; particle density; kinematic viscosity of the fluidising gas; bulk height of bed filling; a geometric factor; and diameter of the enclosure.
