Abstract
The present invention relates to apparatuses for fluidized bed using multiple jets to introduce gas into a fluidized bed region and methods of fluidizing. The apparatus for introducing fluidizing medium to a fluidized bed reactor comprises a vessel defining a fluidized bed region and in which solid feed stock is fed, a gas distribution grid housed in the lower portion of the vessel through which a first fluidizing medium is introduced to fluidize the solid feed stock, a plurality of jets positioned through the gas distribution grid through which a second fluidizing medium is introduced into the fluidized bed region for fluidization of the solid feed stock.
Claims8
An apparatus for introducing fluidizing gas to a fluidized bed reactor, comprising:
- a vertical vessel having a lower portion and defining a fluidized bed region and in which solid feed stock is fed,
- a conically shaped perforated gas distribution grid housed in the lower portion of the vessel through which a first fluidizing medium is introduced to fluidize the solid feed stock, wherein the fluidized bed region is immediately above and a plenum space is immediately underneath the conically shaped perforated gas distribution grid, and
- a plurality of jets positioned through the conically shaped perforated gas distribution grid through which a second fluidizing medium is introduced into the fluidized bed region for fluidization of the solid feed stock, and
- a distribution header, wherein each of the plurality of jets is connected to the distribution header, and wherein the distribution header is connected to a source of the second fluidizing medium,
- wherein the first fluidizing medium and the second fluidizing medium are physically present in the apparatus.
