Oil burner nozzle

Abstract

A burner assembly for a furnace includes: a burner block having a flame cavity with a flame cavity length, and an oil nozzle insert having a tip that extends into the flame cavity by a distance of greater than one tenth of the flame cavity length.

1 . A burner assembly for a furnace comprising: 
 a burner block having a flame cavity with a flame cavity length; and    an oil nozzle insert having a tip that extends into the flame cavity by a distance of greater than one tenth of the flame cavity length.    
   
   
       2 . The burner assembly of  claim 1 , wherein the tip extends approximately one half of the flame cavity length into the flame cavity.  
   
   
       3 . The burner assembly of  claim 1 , wherein the flame cavity of the burner block has a length of between about nine to ten inches, and the oil nozzle insert has a tip that terminates a distance of greater than one inch into the flame cavity.  
   
   
       4 . The burner assembly of  claim 3 , wherein the tip terminates a distance of greater than one inch into the flame cavity.  
   
   
       5 . The burner assembly of  claim 3 , wherein the tip terminates approximately five inches into the flame cavity.  
   
   
       6 . A burner assembly for a furnace comprising: 
 a burner block having a front face and a flame cavity with a flame cavity length; and    an oil nozzle insert having a tip that terminates less than 90% of the flame cavity length from the front face of the burner block.    
   
   
       7 . The burner assembly of  claim 6 , wherein the oil nozzle insert has a tip that terminates at a distance from the front face of the burner block of between about 30% to 40% of the flame cavity length.  
   
   
       8 . The burner assembly of  claim 6 , wherein the oil nozzle insert has a tip that terminates between about three to four inches from the front face of the burner block.  
   
   
       9 . The burner assembly of  claim 6 , wherein the tip terminates less than nine inches from the front face of the burner block.  
   
   
       10 . A burner assembly for a furnace comprising: 
 a burner block having a front face and a flame cavity with a flame cavity length of about five inches or longer; and    an oil nozzle insert having a tip that extends into the cavity and terminates at a distance from the front face of the burner block of between about 30% to 40% of the flame cavity length.    
   
   
       11 . The burner assembly of  claim 10 , wherein the oil nozzle insert has a forward portion with a length about one inch less than the flame cavity length.  
   
   
       12 . The burner assembly of  claim 10 , wherein the oil nozzle insert has a tip that terminates between about three to four inches from the front face of the burner block.
