High Power Dual Gas Burner

Abstract

A high power dual gas burner includes an outer burner and an inner burner. The outer burner includes a first gas input having a first burner head and a first burner cover forming a first combustion chamber. The first burner cover that covers the first burner head includes a conical shaped protrusion in the center extending into the first combustion chamber.

1 . A high power dual gas burner comprising:
 an outer burner and an inner burner, wherein the outer burner having a first gas input and having a first burner head and a first burner cover forming a first combustion chamber, wherein the first burner cover that covers the first burner head, having a conical shaped protrusion in the center extending into the first combustion chamber.   
     
     
         2 . The high power dual gas burner according to  claim 1 , wherein the inner burner having a second burner head and a second burner cover forming a second combustion chamber and having a second gas input which is independent from the first gas input, wherein the inner burner is arranged on top of the first burner cover. 
     
     
         3 . The high power dual gas burner according to  claim 2 , wherein the second burner head being arranged in a depression of the first burner cover. 
     
     
         4 . The high power dual gas burner according to  claim 1 , wherein a diameter of the outer burner is larger than a diameter of the inner burner. 
     
     
         5 . The high power dual gas burner according to  claim 1 , further comprising an igniter adapted to ignite the inner burner. 
     
     
         6 . The high power dual gas burner according to  claim 1 , wherein the first burner head comprises a peripheral wall having annular outlet ports spaced radially. 
     
     
         7 . The high power dual gas burner according to  claim 6 , wherein each annular outlet port is inclined in a horizontal direction relative to a horizontal straight line originating from the center of the first burner head and intersecting the annular outlet port. 
     
     
         8 .
