Claim 0:
1. A method for using a fluid bed regenerative thermal oxidizer, the method comprising:
providing fluid bed regenerative thermal oxidizer comprising: a vertical reactor stack comprising a gas inlet at a lower end of the vertical reactor stack, a gas outlet located at an upper end of the vertical reactor stack and a combustion chamber located within the vertical reactor stack between the gas inlet and the gas outlet wherein the combustion chamber also comprises a fuel burner;
one or more adsorber shelf located within the vertical reactor stack and below the combustion chamber configured to allow air to flow through each adsorber shelf and also configured to contain the heat exchange material and allow the heat exchange material to move across each adsorber shelf and exit one end of each adsorber shelf;
one or more desorber shelf located within the vertical reactor stack and above the combustion chamber configured to allow air to flow through each desorber shelf and also configured to contain the heat exchange material and allow the heat exchange material to move across each desorber shelf and exit one end of each desorber shelf and onto one or more desorber shelf;
an upper heat exchange material container located near the upper end of the vertical reactor stack;
a lower heat exchange material container located near the lower end of the vertical reactor stack;
a vertical tube connecting the upper heat exchange material container and the lower heat exchange material container; and
bypass connecting the lower end of the heating chamber to the lower end of the vertical stack;
providing heat exchange material;
providing a combustion gas; and
adding combustion gas to the combustion chamber and igniting the combustion gas and the untreated gas to form a combusted gas; flowing the combusted gas through at least one desorber shelf containing heat exchange material to heat the heat exchange material; moving the heated heat exchange material from at least one desorber shelf to at least one adsorber shelf flowing the untreated gas though at least one adsorber shelf containing heated heat exchange material so that the untreated gas is heated by the heated heat exchange material and the heat exchange material is cooled by the untreated gas; moving the cooled heat exchange material from at least one adsorber shelf to at least one desorber shelf; and transporting heat exchange material from the lower end of the heating chamber into the lower end of the vertical stack through the bypass.
