Burner for outdoor fire heating appliances

Abstract

A burner for a fire heating appliance may include a plenum for holding a quantity of fuel and a burn surface. The burn surface may include an apex wherein the burn surface slopes away from the apex and a plurality of orifices for passing fuel from the plenum therethrough. Each orifice may be surrounded by a sidewall. An outdoor heating appliance may include a base portion, a top portion, and a burner. The burner may be arranged in the top portion and may be configured for releasing fuel to form a flame. The burner may include a top pan portion and a bottom pan portion. The top and bottom pan portions may be arranged to form a plenum for containing and releasing fuel. The top pan portion may include a plurality of orifices having a raised sidewall.

         5 . The burner of  claim 1 , wherein the plenum comprises:
 a lower burner portion comprising a basin; and   an upper burner portion comprising the burn surface.   
     
     
         6 . The burner of  claim 1 , wherein the plurality of orifices are arranged in a selected design. 
     
     
         7 . An outdoor heating appliance comprising,
 a base portion;   a top portion; and   a burner arranged in the top portion configured for releasing fuel to form a flame, the burner comprising a top pan portion and a bottom pan portion, the top and bottom pan portions being arranged to form a plenum for containing and releasing fuel, the top pan portion comprising a plurality of orifices having a raised sidewall.   
     
     
         8 . The outdoor heating appliance of  claim 7 , wherein the top plate and the bottom plate extend relatively broadly lateral to form an expansive burner surface. 
     
     
         9 . The outdoor heating appliance of  claim 8 , wherein the burner is configured to create a recessed area within the top portion. 
     
     
         10 . The outdoor heating appliance of  claim 7 , wherein the raised sidewall is a sloped sidewall, and the sidewall defines a tapered conduit beneath the orifice. 
     
     
         11 . The outdoor heating appliance of  claim 7 , wherein the top pan portion forms a slope for shedding water. 
     
     
         12 . The outdoor heating appliance of  claim 11 , wherein the burner is arranged on a mounting lip extending around a perimeter of the burner. 
     
     
         13 . The outdoor heating appliance of  claim 12 , wherein the top pan portion slopes upward from the mounting lip to an apex. 
     
     
         14 . The outdoor heating appliance of  claim 13 , wherein the apex is arranged generally centrally within the burner. 
     
     
         15 . The outdoor heating appliance of  claim 7 , further comprising a side burner portion configured to recess the plenum within the fire heating appliance. 
     
     
         16 . The outdoor heating appliance of  claim 15 , further comprising a spacer arranged between the side burner portion and the plenum and further defining a channel between the side burner portion and the plenum. 
     
     
         17 . The outdoor heating appliance of  claim 16 , wherein the bottom pan portion comprises a basin and the top pan portion comprises a burn surface. 
     
     
         18 . The outdoor heating appliance of  claim 17 , wherein the plurality of orifices are arranged in a selected design. 
     
     
         19 . The outdoor heating appliance of  claim 7 , further comprising a gas source in communication with the plenum. 
     
     
         20 . The outdoor heating appliance of  claim 19 , further comprising a gas regulator in fluid communication with the plenum and the gas source.
