INSTRUMENTS FOR MONITORING ELECTROSTATIC PHENOMENA IN REACTORS

摘要

Probes for monitoring electrostatic phenomena in challenging environments, such as fluidized bed reactors. These probes include a coated or uncoated static probe for measuring electric field and or particle charge state, an oscillatory electric field probe for measuring electric field, a chopped electric field probe for measuring electric field, and a radio-frequency antenna probe for detecting electrostatic discharges.

主权项

1. A coated static probe which monitors the electrostatic charge on particles entrained in the gas stream of a vessel, said probe comprising:
an electrode with a modified surface comprising an electrically insulating coating, thereby mitigating triboelectrification of said probe arising from charge transfer from impinging particulates and extraneous signals via charge saturation of said coating.
