Jet burner construction, heating apparatus utilizing the jet burner construction and methods of making the same

Claim 2

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 from 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, the improvement wherein said burner construction comprises flame retainer means carried by said body means and having outer edge means extending beyond said outlet opening means of said body means to restrict the flows of induced air between the flows of fuel issuing from said radiating portions of said outlet opening means.

Claim 3

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, said flame retaining means comprising two sections each having like side edge means facing said side edge means of the other section and being separated therefrom by said wing-like extensions.

Claim 4

A jet burner construction as set forth in claim 2 wherein each said section of said flame retaining means has two spaced apart said side edge means and an arcuate intermediate portion interconnecting said side edge means thereof together.

Claim 5

A jet burner construction as set forth in claim 2 wherein said burner body means is 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 wing-like extensions thereon.

Claim 6

A jet burner construction as set forth in claim 4 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.

Claim 7

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 from 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 a 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, the improvement wherein said burner construction comprises flame retainer means carried by said body means and having outer edge means extending beyond said outlet opening means of said body means to restrict the flows of induced air between the flows of fuel issuing from said radiating portions of said outlet opening means.

Claim 8

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 from 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 a 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, the improvement wherein said burner construction comprises flame retainer means carried by said body means and having outer edge means extending beyond said outlet opening means of said body means to restrict the flows of induced air between the flows of fuel issuing from said radiating portions of said outlet opening means.

Claim 9

A heating apparatus as set forth in claim 6 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, said flame retaining means comprising two sections each having like side edge means facing said side edge means of the other section and being separated therefrom by said wing-like extensions.

Claim 10

A heating apparatus as set forth in claim 7 wherein each said section of said flame retaining means has two spaced apart said side edge means and an arcuate intermediate portion interconnecting said side edge means thereof together.

Claim 11

A heating apparatus as set forth in claim 7 wherein said burner body means is 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 wing-like extensions thereon.

Claim 12

A heating apparatus as set forth in claim 9 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.
