Burner and boiler/furnace for pressurized oxy-combustion boilers and furnaces

Abstract

The present disclosure is generally directed to a burner and boiler/furnace for pressurized oxy-combustion boilers and furnaces. The disclosure includes a design of a burner and boiler for a staged, pressurized oxy-combustion (SPOC) technology process and designs that affect wall heat flux. The disclosure further includes the introduction of wall rings to increase, for example, advection.

What is claimed is: 
     
         1 . A staged, pressurized oxy-combustion system, the system comprising:
 a unique design including at least one burner, at least one boiler and a central oxygen stream.   
     
     
         2 . (canceled) 
     
     
         3 . The system of  claim 1 , wherein the design further includes an annulus comprising a fuel. 
     
     
         4 . The system of  claim 1 , wherein the central oxygen stream is surrounded by the fuel. 
     
     
         5 . The system of  claim 1 , wherein the design further includes a secondary oxidizer stream. 
     
     
         6 . The system of  claim 5 , wherein the secondary oxidizer stream surrounds the central oxygen stream. 
     
     
         7 . A method of capturing carbon dioxide, the method comprising:
 using a staged, pressurized oxy-combustion system including a unique design, where the design includes at least one burner, at least one boiler and a central oxygen stream.   
     
     
         8 . (canceled) 
     
     
         9 . The method of  claim 7 , wherein the design further includes an annulus comprising a fuel. 
     
     
         10 . The method of  claim 7 , wherein the central oxygen stream is surrounded by the fuel. 
     
     
         11 . The method of  claim 7 , wherein the design further includes a secondary oxidizer stream. 
     
     
         12 . The method of  claim 11 , wherein the secondary oxidizer stream surrounds the central oxygen stream. 
     
     
         13 . The method of  claim 7 , further including reducing a flue gas cycle. 
     
     
         14 . The method of  claim 13 , wherein the flue gas cycle is reduced by radiative trapping. 
     
     
         15 . The method of  claim 13 , wherein the flue gas cycle is reduced by creating a long flame to evenly distribute a wall heat flux. 
     
     
         16 . A staged, pressurized oxy-combustion system, the system comprising:
 a unique design including at least one burner and at least one boiler, wherein the boiler includes at least one wall ring.   
     
     
         17 . The system of  claim 16 , wherein the design further includes a central oxygen stream. 
     
     
         18 . The system of  claim 17 , wherein the design further includes an annulus comprising a fuel. 
     
     
         19 . The system of  claim 17 , wherein the central oxygen stream is surrounded by the fuel. 
     
     
         20 . The system of  claim 17 , wherein the design further includes a secondary oxidizer stream. 
     
     
         21 . The system of  claim 20 , wherein the secondary oxidizer stream surrounds the central oxygen stream. 
     
     
         22 - 32 . (canceled) 
     
     
         33 . The system of  claim 1 , wherein the burner includes at least one flame holder ring. 
     
     
         34 . (canceled)
