Abstract

A flameless thermal oxidizer (FTO) includes at least one baffle constructed and arranged in a reaction chamber of the FTO to coact with a diptube of the FTO to radially expand a resulting “bubble” or reaction envelope from the diptube outward into a porous matrix of the FTO. A related method is also provided.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A flameless thermal oxidizer (FTO), comprising:
 at least one baffle constructed and arranged in a reactive chamber of the FTO to coact with a diptube of the FTO to radiate and expand a resulting reaction envelope from the diptube outward into a porous matrix of the FTO.   
     
     
         2 . The FTO of  claim 1 , wherein the at least one baffle is constructed from a material selected from the group consisting of an impermeable material, and a semi-permeable material. 
     
     
         3 . The FTO of  claim 1 , wherein the at least one baffle is positioned in the reactive chamber at a surface of the porous matrix. 
     
     
         4 . The FTO of  claim 1 , wherein the reaction envelope comprises a bubble shape beneath the at least one baffle. 
     
     
         5 . The FTO of  claim 1 , wherein the at least one baffle extends across a substantial portion of a surface area of the porous matrix. 
     
     
         6 . The FTO of  claim 1 , wherein the at least one baffle is positioned in the reactive chamber below a surface of the porous matrix. 
     
     
         7 . The FTO of  claim 6 , wherein the at least one baffle is positioned closer to an outlet of the diptube than the surface of the porous mixture. 
     
     
         8 . The FTO of  claim 6 , wherein the at least one baffle is constructed from a material selected from the group consisting of an impermeable material, and a semi-permeable material. 
     
     
         9 . The FTO of  claim 1 , wherein the at least one baffle is an upper baffle positioned in the reactive chamber at a surface of the porous matrix, and further comprising a lower baffle positioned in the reactive chamber below the surface of the porous mixture and spaced apart from the upper baffle. 
     
     
         10 . The FTO of  claim 9 , wherein the upper and lower baffles each comprise similar shapes and have similar surface areas. 
     
     
         11 . The FTO of  claim 10 , wherein the upper and lower baffles are each constructed from a material selected from the group consisting of an impermeable material and a semi-permeable material. 
     
     
         12 . The FTO of  claim 9 , wherein the positioning of the upper and lower baffles in the spaced apart relation in the porous matrix provides increased residence time and a variable expanding flow path for the reaction envelope in the porous matrix. 
     
     
         13 . The FTO of  claim 9 , further comprising a central baffle positioned in the porous matrix between and spaced apart from each of the upper baffle and the lower baffle. 
     
     
         14 . The FTO of  claim 13 , wherein the upper, lower and central baffles each have a different size and surface area. 
     
     
         15 . A method of controlling a reaction envelope in a porous matrix of a flameless thermal oxidizer (FTO), comprising:
 positioning at least one baffle in the porous matrix for coacting with the reaction envelope emitted from a diptube of the FTO; and   interrupting upward flow of the reaction envelope with the at least one baffle for radially expanding said reaction envelope in said porous matrix.   
     
     
         16 . The method of  claim 15 , wherein the reaction envelope is bubble-shaped. 
     
     
         17 . The method of  claim 15 , wherein the expanding occurs in the porous matrix beneath the at least one baffle. 
     
     
         18 . The method of  claim 17 , wherein the expanding of the reaction envelope provides increasing a residence time of the reaction envelope in the porous matrix after being emitted from the diptube. 
     
     
         19 . The method of  claim 15 , wherein the positioning of the at least one baffle is at a surface of the porous matrix. 
     
     
         20 . The method of  claim 15 , further comprising providing a second baffle in the porous matrix below and spaced apart from the at least one baffle. 
     
     
         21 . The method of  claim 20 , wherein the providing of the second baffle is closer to an outlet of the diptube then to the at least one baffle. 
     
     
         22 . The method of  claim 20 , further comprising providing a third baffle in the porous matrix between and spaced apart from the at least one baffle and the second baffle. 
     
     
         23 . The method of  claim 22 , wherein the least one, second and third baffles provide a flow path varying and increasing residence time of the reaction envelope in the porous matrix. 
     
     
         24 . The method of  claim 15 , wherein the radially expanding the reaction envelope comprises downward movement of said reaction envelope in the porous matrix.
