Regenerative thermal oxidizer, system comprising a regenerative thermal oxidizer and method of operating a regenerative thermal oxidizer

A system comprising a regenerative thermal oxidizer, wherein the regenerative thermal oxidizer comprises:

• at least a first transfer chamber and at least a second transfer chamber, wherein the first transfer chamber comprises a first bed, and the second transfer chamber comprises a second bed;
• at least one reaction chamber in fluid flow communication with the first transfer chamber and with the second transfer chamber, wherein waste gas is introducible into the regenerative thermal oxidizer to flow through the first bed to the at least one reaction chamber or to flow through the second bed to the at least one reaction chamber;
• and
• one or more first oxygen-containing gas inlets through which oxygen-containing gas is introduced into the regenerative thermal oxidizer, wherein the first oxygen-containing gas inlets are positioned between at least a portion of the first bed and at least a portion of the at least one reaction chamber or positioned between at least a portion of the second bed and at least a portion of the at least one reaction chamber,
• wherein the one or more first oxygen-containing gas inlets are positioned between at least a portion of the first bed and at least a portion of the at least one reaction chamber, and the regenerative thermal oxidizer further comprises one or more second oxygen-containing gas inlets through which oxygen-containing gas is introduced into the regenerative thermal oxidizer, wherein the one or more second oxygen-containing gas inlets are positioned between at least a portion of the second bed and at least a portion of the at least one reaction chamber.
