Control of bed height in a fluidized bed gasification system

Patent · 20 December 1983

OSTI ID:864802

Mehta, Gautam I.; Rogers, Lynn M.

In a fluidized bed apparatus a method for controlling the height of the fdized bed, taking into account variations in the density of the bed. The method comprises taking simultaneous differential pressure measurements at different vertical elevations within the vessel, averaging the differential pressures, determining an average fluidized bed density, then periodically calculating a weighting factor. The weighting factor is used in the determination of the actual bed height which is used in controlling the fluidizing means.
