Pulse process, for operating fluidized bed reactor, e.g. for incineration of solid wastes, involves forming isochronous, isohaline and/or insulating annular flow of varying temperature or concentration between raw gas and pipe wall

摘要

In a fluidized bed reactor, e.g. for the incineration of waste materials, the gases pass through the bed at high speed. The gases form an isochronous, isohaline and/or insulating annular flow of varying temperature or concentration between the raw gas and the pipe wall. The gas flow is maintained at a steady speed of 5 - 300 m/s. A jet lance releases an aqueous medium of defined pH, or an organic medium (e.g. oil), or steam, into the gas at the point of highest speed and towards the flow filaments. The media are introduced in alternating pulses.
