Ground flare

Abstract

A ground flare for treating waste gas comprises a rectangular enclosure including opposing first and second side walls and opposing first and second end walls. The first and second side walls have a greater length than the first and second end walls. At least one air opening is formed in each of the first and second side walls for receiving air. At least one burner extends horizontally through each of the at least one air opening and into the enclosure. Each burner includes a fuel port disposed inside of the enclosure for injecting the waste gas into the enclosure.

What is claimed is: 
     
         1 . A ground flare for treating waste gas, the ground flare comprising:
 a rectangular enclosure including opposing first and second side walls and opposing first and second end walls, wherein the first and second side walls have a greater length than the first and second end walls;   at least one air opening formed in each of the first and second side walls for receiving air; and   at least one burner extending horizontally through each of the at least one air opening and into the enclosure, each burner including a fuel port disposed inside of the enclosure for injecting the waste gas into the enclosure.   
     
     
         2 . The ground flare of  claim 1 , wherein the enclosure extends upwardly from ground. 
     
     
         3 . The ground flare of  claim 1 , further comprising:
 a rectangular wind fence surrounding said enclosure, wherein said enclosure is substantially centered within the wind fence.   
     
     
         4 . The ground flare of  claim 1 , wherein the enclosure comprises a lower portion and an upper portion. 
     
     
         5 . The ground flare of  claim 1 , said at least one air opening comprises a plurality of air openings formed along the length of each of the first and second side walls. 
     
     
         6 . The ground flare of  claim 5 , wherein the plurality of air openings on the first side wall are aligned with the plurality of air openings on the second side wall. 
     
     
         7 . The ground flare of  claim 5 , wherein said at least one burner comprises a plurality of burners coupled to a manifold disposed above said air opening. 
     
     
         8 . The ground flare of  claim 5 , wherein said at least one burner comprises a plurality of sets of burners, each set of burners being coupled to a manifold disposed above said air opening. 
     
     
         9 . The ground flare of  claim 1 , further comprising:
 at least one air entrainment port formed into each of the first and second end walls for receiving air therethrough.   
     
     
         10 . A ground flare for treating waste gas, the ground flare comprising:
 a rectangular enclosure including opposing first and second side walls and opposing first and second end walls, wherein the first and second side walls have a greater length than the first and second end walls;   each of the first and second side walls comprising a plurality of segments, each segment including at least one air opening formed therein for receiving air; and   at least one burner extending horizontally through each of the at least one air opening and into the enclosure, each burner including a fuel port disposed inside of the enclosure for injecting the waste gas into the enclosure.   
     
     
         11 . The ground flare of  claim 10 , wherein each burner comprises:
 a pipe that extends through the air opening; and   a flare tip comprising a plurality of the fuel ports.   
     
     
         12 . The ground flare of  claim 10 , wherein said at least one burner comprises a plurality of burners, each burner comprising:
 a pipe that extends through the air opening; and   a flare tip comprising a plurality of the fuel ports.   
     
     
         13 . The ground flare of  claim 11 , further comprising:
 a plurality of steam injection ports disposed in the enclosure.   
     
     
         14 . The ground flare of  claim 10 , wherein each of the segments is substantially identical. 
     
     
         15 . The ground flare of  claim 10 , wherein the air openings comprise windows formed into the first and second side walls. 
     
     
         16 . The ground flare of  claim 10 , further comprising:
 at least one air entrainment port formed into each of the first and second end walls for receiving air therethrough.   
     
     
         17 . The ground flare of  claim 10 , wherein each of the first and second side walls and the first and second end walls comprises upper and lower sections. 
     
     
         18 . A ground flare for treating waste gas, the ground flare comprising:
 a rectangular enclosure including opposing first and second non-firing walls and opposing first and second firing walls, the first and second firing walls comprising a plurality of repeating segments, each segment including at least one air opening formed therein for receiving air; and   a plurality of burners extending horizontally from outside the enclosure through each of the at least one air opening and into the enclosure, each burner including a fuel port disposed inside of the enclosure for injecting the waste gas into the enclosure.   
     
     
         19 . The ground flare of  claim 18 , wherein, for each air opening, the plurality of burners are coupled to a manifold disposed above the air opening. 
     
     
         20 . The ground flare of  claim 18 , further comprising:
 a wind fence disposed around the enclosure and surrounding the enclosure;   wherein the enclosure is centered within the wind fence.
