Claims
- 1. In a jet burner construction comprising a burner body means having a chamber means therein and having an inlet means leading to said chamber means for directing fuel form a fuel source therein and an outlet means leading from said chamber means and defining an outlet opening means through which said fuel is adapted to issue from said chamber means to burn externally to said burner body means, said outlet opening means having a central opening part and a plurality of spaced apart opening portions interconnected thereto and radiating outwardly therefrom whereby flows of fuel respectively issuing out of said portions and said central part of said outlet opening means merge together in a turbulent manner externally of said outlet opening means, said burner construction comprising flame retainer means carried by said body means and having outer edge means extending beyond said outlet opening means of said body means to prevent flows of induced air from being created between the flows of fuel issuing from said radiating portions of said outlet opening means, said burner body means being formed of two generally similar body sections secured together in superimposed relation and each having generally one-half of said outlet opening means and one-half of said flame retainer means thereon, the improvement wherein said body means has opposed ends and has a fluted portion disposed spaced from and intermediate said opposed ends of said body means, said fluted portion having opposed ends, said fluted portion defining said central opening part and said radiating portions of said outlet opening means, said outlet opening means being generally located in the middle of said fluted portion, said fluted portion expanding and extending axially beyond said central opening part at one of said opposed ends of said fluted portion and comprising part of said flame retainer means, said flame retainer means also comprising a generally ring-like structure between said one of said opposed ends of said fluted portion and one of said opposed ends of said body means, each one-half of said flame retainer means being integral and one-piece with its respective body section.
- 2. A jet burner construction as set forth in claim 1 wherein said burner body means has wing-like extensions respectively disposed on opposite sides thereof for respectively interconnecting with adjacent wing-like extensions of adjacent burner constructions, each body section having generally one-half of said wing-like extensions thereon.
- 3. A jet burner construction as set forth in claim 2 wherein said wing-like extensions each has an elongated outlet slot means interconnecting with said outlet opening means and through which fuel is adapted to issue so as to burn external to said wing-like extensions.
- 4. In a heating apparatus comprising a heating tube means provided with an inlet and a jet burner construction comprising a burner body means having a chamber means therein and having an inlet means leading to said chamber means for directing fuel form a fuel source therein and an outlet means leading from said chamber means and defining an outlet opening means through which said fuel is adapted to issue from said chamber means to burn externally to said burner body means and enter said heating tube means through said inlet thereof, said outlet opening means having a central opening part and a plurality of spaced apart opening portions interconnected thereto and radiating outwardly therefrom whereby flows of fuel respectively issuing out of said portions and said central part of said outlet opening means merge together in a turbulent manner externally of said outlet opening means, said burner construction comprising flame retainer means carried by said body means and having outer edge means extending beyond said outlet opening means of said body means to prevent flows of induced air from being created between the flows of fuel issuing from said radiating portions of said outlet opening means, said burner body means being formed of two generally similar body sections secure together in superimposed relation and each having generally one-half of said outlet opening means and one-half of said flame retainer means thereon, the improvement wherein said body means has opposed ends and has a fluted portion disposed spaced from and intermediate said opposed ends of said body means, said fluted portion having opposed ends, said fluted portion defining said central opening part and said radiating portions of said outlet opening means, said outlet opening means being generally located in the middle of said fluted portion, said fluted portion expanding and extending axially beyond said central opening part at one of said opposed ends of said fluted portion and comprising part of said flame retainer means, said flame retainer means also comprising a generally ring-like structure between said one of said opposed ends of said fluted portion and one of said opposed ends of said body means, each one-half of said flame retainer means being integral and one-piece with its respective body section.
- 5. A heating apparatus as set forth in claim 4 wherein said burner body means has wing-like extensions respectively disposed on opposite sides thereof for respectively interconnecting with adjacent wing-like extensions of adjacent burner constructions, each body section having generally one-half of said wing-like extensions thereon.
- 6. A heating apparatus as set forth in claim 5 wherein said wing-like extensions each has an elongated outlet slot means interconnecting with said outlet opening means and through which fuel is adapted to issue so as to burn external to said wing-like extensions.
