Low oxygen vortex burner

Abstract

A low oxygen vortex burner is provided. With the use of exhaust gas discharged from a combined boiler internal combustion engine as a supply source of air for re-combustion, it is possible to have the exhaust gas discharged in a state of complete combustion and to suppress the pollution of the natural environment due to the exhaust gas. The low oxygen vortex burner includes: a frame 100 including a barrier plate 130 for segmenting an inlet space 110 and a combustion chamber 120; an outer casing 220 having a plurality of vortex pipes 400 arranged thereon with the same intervals in a tangential direction of the outer casing so as to cause a vortex of the exhaust gas introduced from said inlet space 110 of the frame 100; a nozzle 500 installed along an axial direction of said outer casing 200 and injecting fuel for combustion; an orifice 800 formed at a location corresponding to an end of said nozzle 500 and passing the exhaust gas in the outer casing 200 and the fuel with a higher speed for accelerating the combustion; a choke 700 formed at the opposite side of said orifice 800 located at a side of said combustion chamber 120 so as to re-circulate a flame within the combustion chamber 120; and fire-resistive materials 600 surrounding the combustion chamber 120 except for said choke 700 and said orifice 800.

1 . A low oxygen vortex burner comprising:
 a frame  100  including a barrier plate  130  for segmenting an inlet space  110  for receiving exhaust gas and a combustion chamber  120 ;   an outer casing  220  having a plurality of vortex pipes  400  arranged thereon with the same intervals in a tangential direction of the outer casing so as to cause a vortex of the exhaust gas introduced from said inlet space  110  of the frame  100 ;   a nozzle  500  installed along an axial direction of said outer casing  200  and injecting fuel for combustion;   an orifice  800  formed at a location corresponding to an end of said nozzle  500  and passing the exhaust gas in the outer casing  200  and the fuel with a higher speed for accelerating the combustion;   a choke  700  formed at the opposite side of said orifice  800  located at a side of said combustion chamber  120  so as to re-circulate a flame within the combustion chamber  120 ; and   fire-resistive materials  600  surrounding the combustion chamber  120  except for said choke  700  and said orifice  800 .   
   
   
       2 . A low oxygen vortex burner as claimed in  claim 1 , wherein said inlet space  110  is formed with a connection hole  111  to which a exhaust pipe of a combined boiler internal combustion engine is coupled for discharging the exhaust gas. 
   
   
       3 . A low oxygen vortex burner as claimed in  claim 1 , wherein said outer casing  200  includes a funnel shape with a narrow exit. 
   
   
       4 . A low oxygen vortex burner as claimed in  claim 1 , wherein each of said vortex pipes  400  is installed on said outer casing  200  in such a manner that an angle ranging from 20 to 60 is formed between each of the vortex pipes  400  and the tangential line extended from the circumference of the outer casing  200 .
