Superheating burner with turbulence ring

Abstract

A device for combusting liquid fuel includes a cylinder sealed at both ends by respective annular seals. The liquid fuel is vaporized and flows through a tube extending into a sealed space between the cylinder walls. The tube is removably sealed to an end of an air mixing barrel that extends into the cylinder. The air mixing barrel has a plurality of air intake holes and a plurality of gas spray holes through which the vaporized fuel/air mixture exits. The device also includes a turbulence ring that is rotatably adjustable about a second end of the air mixing barrel. The air mixing barrel also includes an orifice that increase a pressure in the orifice to decrease carbon monoxide emissions.

       3 . The device as claimed in  claim 2 , wherein said air intake holes are outside of said area defined by said inner wall.  
   
   
       4 . The device as claimed in  claim 2 , wherein said inner wall extends beyond said second end of said cylinder by approximately two inches.  
   
   
       5 . The device as claimed in  claim 1 , wherein said turbulence ring has a beveled edge.  
   
   
       6 . The device as claimed in  claim 5 , wherein a widest part of said beveled edge is closest to said plural gas spray holes.  
   
   
       7 . The device as claimed in  claim 1 , wherein said air mixing barrel has a beveled edge at a first end, said plural gas spray holes being in said beveled edge.  
   
   
       8 . The device as claimed in  claim 7 , wherein said plural gas spray holes are substantially perpendicular to said beveled edge.  
   
   
       9 . The device as claimed in  claim 1 , further comprising an orifice connected between said second end of said second tube and said mixing barrel that creates pressure in said mixing barrel when said superheated gas flows therethrough.  
   
   
       10 . The device as claimed in  claim 1 , wherein the cylinder is approximately one foot long and has an outside diameter of approximately two and one-quarter inches.  
   
   
       11 . A device for combusting liquid fuel, comprising: 
 a cylinder having an inner wall and an outer wall with a sealed space therebetween, said inner wall defining a heating chamber separate from said space;    a first pipe supplying gas to said space;    an air mixing barrel having a first end extending into said cylinder and having a plurality of air intake holes between said first end and an opposing second end, a plurality of gas spray holes being at said first end;    a second pipe extending from said space to said second end of said air mixing barrel for supplying said gas, as superheated gas, to said air mixing barrel; and    a turbulence ring adjacent said first end and rotatably adjustable about said air mixing barrel.    
   
   
       12 . The device as claimed in  claim 11 , wherein said mixing barrel further comprises an orifice.  
   
   
       13 . A method of superheating a gas to reduce carbon monoxide emissions, comprising the steps of: 
 delivering a liquid to a first end of a first tube;    vaporizing said liquid to form a combustible gas;    discharging said gas from a second end of the first tube adjacent a first end of a double walled cylinder;    heating said double walled cylinder;    flowing the gas between walls of the double walled cylinder from the first end of the cylinder toward a second end of the cylinder, so that the gas enters a second tube at the second end of the cylinder as a superheated gas;    passing the superheated gas through the second tube, so that the superheated gas flows through the second tube from the second end of the cylinder back toward the first end of the cylinder, on a side of the cylinder opposite that of the first tube;    mixing the superheated gas with air in an air mixing barrel that partially extends into the cylinder;    igniting the air/superheated gas mixture in the air mixing barrel at a temperature that reduces carbon monoxide level;    ejecting the ignited air/gas mixture from a plurality of spray holes on an end of the air mixing barrel into the cylinder to develop a secondary flow of air into the first end of the cylinder.    
   
   
       14 . The method according to  claim 14 , further comprising the step of adjusting a turbulence ring around the air mixing barrel to regulate zones of pressure differential upstream and downstream of the turbulence ring in a direction of the secondary flow of air.
