High performance burner

Abstract

A high performance burner has a shell, a burning chamber contained in the shell, an ignition bar installed in the shell, and a fuel feeding means passing through the shell and being in communication with the burning chamber. The burning chamber has a first burning zone in communication with the exit of the feeding pipe, a second burning zone next to the first burning zone, and a third burning zone next to the second burning zone and in communication with the rear opening of the shell. The burner is able to effectively reduce fuel congestion, scorification and back fire and increase combustion efficiency.

1 . A high performance burner comprising:
 a shell, a burning chamber contained in said shell, an ignition bar installed in said shell, and a fuel feeding means passing through said shell and being in communication with said burning chamber,   said shell having a bottom, a pair of side plates extending upward from said bottom, a top opening above said bottom, a front plate extending upward from said bottom, and a rear opening opposite to said front plate, an ignition bar installation hole being defined respectively in each side plate, an air vent being defined in said front plate close to said bottom,   said fuel feeding means having a feeding pipe passing through said front plate of said shell and a spiral shaft rotatably contained in said feeding pipe, a feeding window being defined in a wall of said feeding pipe sticking out from said shell, said feeding pipe having a fuel exit and at least one row of a plurality of air supply holes defined in said wall thereof within said shell, each air supply holes being oblique to said burning chamber,   said burning chamber having a first burning zone in communication with said exit of said feeding pipe, a second burning zone next to said first burning zone, and a third burning zone next to said second burning zone and in communication with said rear opening of said shell,   said first burning zone having a roughly level first bottom, a pair of oblique first side plates, a first front plate extending upward from said first bottom, and a first top opening opposite to said first bottom, said exit going through said first front plate, making said feeding pipe be in communication with said first burning zone, a distance between said pair of first side plates being basically the same a width of said exit at said exit and gradually increasing along a direction from said first to said second burning zone, an ignition bar slot being defined in said first bottom up right with respect to said feeding pipe, at least one row of air curtain vents being defined in said first bottom between said ignition bar slot and said exit,   said second burning zone having a second bottom obliquely extending downward from said first bottom and a second top opening opposite to said second bottom,   said third burning zone having a third bottom, a front upright plate extending from said third bottom to said, second bottom, a rear upright plate extending from said third bottom to said bottom, and a third top opening opposite to said third bottom,   a front top cover being, formed between said front plate and said first front plate, a side top cover being formed respectively between each first side plate and each side plate of the same side,   an air splitter being formed on said front plate extending inward into said shell, said air splitter having a level portion and a tilting portion, said level portion going across said air vent, making an area of said air vent above said level portion be two times of said area below said level portion, a free end of said tilting portion points to a conjunction line between said first and said second bottoms,   a wind shield under said ignition bar, being formed on said first bottom and facing towards a direction of said air vent,   a thermostable second side plate on each of said two sides of said second burning zone, and,   a deflector being formed on said first front plate above said exit.   
     
     
         2 . The high performance burner as claimed in  claim 1 , wherein a diameter of each air supply holes is from 3 to 5 millimeters, each row has from 10 to 20 air supply holes, a diameter of said feeding pipe is from 80 to 100 millimeter, a length of said first bottom from said exit to said second burning zone is from 80 to 150 millimeter, a distance between said ignition bar slot and said exit is from 20 to 40 millimeter, an oblique angle of said second bottom with respective to said first bottom is from 8 to 30 degree, a length of said second bottom from said first bottom to said front upright plate is from 60 to 130 millimeter, a height of said front upright plate is from 80 to 150 millimeter, a length of said third bottom from said front to said rear upright plates is from 80 to 150 millimeter, widths of said second bottom, said third bottom, said front upright plate and said rear upright plate are from 80 to 120 millimeter, and, a diameter of said air supply openings is from 2 to 4 millimeter. 
     
     
         3 . The high performance burner as claimed in  claim 2 , wherein said diameter of each air supply holes is 3.5 millimeter, each row has 16 air supply holes, said diameter of said feeding pipe is 90 millimeter, said length of said first bottom from said exit to said second burning zone is 120 millimeter, said distance between said ignition bar slot and said exit is 25 millimeter, said oblique angle of said second bottom with respective to said first bottom is 17 degree, said length of said second bottom from said first bottom to said front upright plate is 100 millimeter, said height of said front upright plate is 120 millimeter, said length of said third bottom from said front to said rear upright plates is 120 millimeter, widths of said second bottom, said third bottom, said front upright plate and said rear upright plate are 100 millimeter, and, said diameter of said air supply openings is 3.5 millimeter.
