Definitions

  • ABSTRACT An improved gas burner apparatus of the type having a hollow inner liner supported within an outer shell, such that combustion air injected between the inner liner and the outer shell travels in a generally helical path to the rear end portion of the inner liner and thoroughly mixes with fuel injected into the end of the outer shell, the fuel and combustion air being mixed and burned generally within the inner liner.
  • a gas burner apparatus is disclosed in detail in US. Pat., No. 3,265,113, which is assigned to the assignee of the present invention, having an outer shell and a coaxial inner liner, wherein pressurized combustion air is injected into the space generally between the inner liner and the outer shell, and fuel is injected into a space generally between the rear end of the inner liner and the rear end of the outer shell.
  • the combustion air injected into the gas burner apparatus travels in a helical path toward the fuel injection portion of the gas burner apparatus generating a vortex which results in a thorough mixing of the fuel and the combustion air, the mixed fuel and combustion air being burned generally within the interior of the innerliner.
  • the present invention contemplates an improved gas burner apparatus including: a hollow outer shell, having a front end and a rear end. A front end wall is secured to the front end, and a rear end wall, having an opening formed therethrough, is secured to the rear end of the outer shell, thereby closing the rear end.
  • a noise abatement apparatus having an aperture means formed therethrough, is secured to the rear end of the inner liner and extends a distance therefrom generally between the rear end of the inner liner and the rear end wall, to diffuse a portion of the combustion air thereby substantially eliminating undesirable noise during the operation of the gas burner apparatus.
  • a flame protection apparatus having an aperture means formed therethrough is secured to a portion of the rear end wall, and substantially encompasses the opening through the rear end wall to diffuse a portion of the combustion air thereby preventing the combustion air from blowing out the pilot flame.
  • An object of the invention is to provide gas burner apparatus having a substantially reduced noise level during the operation thereof.
  • Another object of the invention is to provide a gas burner apparatus wherein the pilot flame is protected from being blown-out during the operation thereof.
  • An additional object of the invention is to provide a gas burner apparatus utilizing injected, pressurized combustion air, wherein the heat output of the gas burner apparatus can be controlled independent of the flow of injected, pressurized combustion air.
  • FIG. -1 is a partial sectional, partial diagrammatical view of a gas burner apparatus constructed in accordance with the present invention.
  • FIG. 4 is an end view of the flame protection apparatus of the gas burner apparatus of FIG. 1.
  • a gas burner which includes; a hollow outer shell 12, having a front end 14 and a rear end 16; and a hollow inner liner 18, having a front end 20 and a rear end 22, which is supported generally within the hollow portion of the outer shell 12.
  • a front end wall 24 is secured to the front end 14 of the outer shell 12, thereby closing the front end portion 14, as shown in FIG. 1.
  • a rear end wall 26 is secured to the rear end portion 16 of the outer shell 12, thereby closing the rear end 16.
  • the the inner liner 18 is supported withing the hollow portion of the outer shell 12 and spaced a distance therefrom about the entire outer periphery of the inner liner 18, to form an air passageway, designated in FIG. 1 by the reference numeral 28, generally between the inner liner l8 and the outer shell 12.
  • a flame protection apparatus 74 having an outer periphery 76 and opposite ends 78 and 80, is disposed adjacent the rear end wall 26, and positioned thereon to encompass the opening 46 through the rear end wall 26.
  • the flame protection apparatus 74 is, in a preferred form, cylindrically shaped, as shown in FIG. 4.
  • the flame protection apparatus 74 includes a plurality of apertures 82 formed through the outer periphery 76 thereof and has a diameter 84 formed by the outer periphery 76.
  • a portion of the combustion air vortex existing in the ignition space 48 is diffused by the noise abatement apparatus 54. More particularly, a portion of the combustion air vortex in the ignition space 48 generally near the rear end 22 of the inner liner 18 is diffused by the noise abatement apparatus 54, during the operation of the gas burner apparatus 10. It has been found that the velocity of the combustion air and the combustion air vortex per se existing generally near the rear end 22 of the inner liner 18 has contributed substantially to the high noise level, common in gas burners of a design similar to that described above with respect to the gas burner 10.
  • the gas burner apparatus 10 is utilized to provide heat for a process fluid, and the amount of heat being provided by the gas burner apparatus 10 at any particular instant is controlled by various process characteristics. It thus becomes necessary, in many instances, to cycle the operation of the gas burner apparatus 10 or, in other instances, to reduce the amount of heat being provided by the gas burner apparatus 10 at a particular time. During such times when the gas burner apparatus 10 is cut-off or the heat being provided thereby is substantially reduced, it is desirable, in most instances to maintain the flow of combustion air through the gas burner apparatus 10 at or near a maximum, thereby permitting the combustion air to be utilized to cool the process fluid.
  • the flame provided via the gas burner apparatus 10 can be effectively controlled, independent of the combustion air flow through the air inlet 30.
  • the heat output of the gas burner apparatus 10 can be controlled over a wide range while leaving the combustion air flow to the gas burner apparatus 10 at or near a predetermined maximum flow leveL
  • the flame protection apparatus 74 substantially prevents the combustion air from blowing out the pilot flame, thereby permitting the gas burner apparatus 10 to be utilized more efiiciently in an overall process.
  • the gas burner apparatus 10 thus provides a gas burner which can be more economically and efficiently operated and which will operate in a more efficient manner in cooperation with a particular process.
  • the gas burner apparatus 10 can thus be constructed in a more economical manner, and will operate at a substantially reduced noise level and in such a manner that the maintaining of the pilot flame is virtually assured.
  • a gas burner apparatus comprising:
  • a hollow outer shell having a front end and a rear end;
  • a rear end wall having an opening formed therethrough, secured to the rear end of the outer shell, thereby closing the rear end;
  • a hollow inner liner having a front end and a rear end, the inner liner supported within the hollow portion of the outer shell and being spaced from the outer shell to form an air passageway between the outer shell and the inner liner, the front end of the inner liner extending through the front end wall and rear end of the inner liner being spaced a predetermined distance from the rear end wall;
  • a noise abatement apparatus including an annular member having perforations about its periphery and, secured to the rear end of the inner liner and extending a distance therefrom generally between the rear end of the inner liner and the rear end wall, to diffuse a portion of the combustion air thereby substantially eliminating undesirable noise during the operation of the gas burner apparatus;
  • pilot flame protection apparatus an annular member having perforations about its periphery secured to a portion of the rear end wall, the flame protection apparatus substantially encompassing the opening through the rear end wall to diffuse a portion of the combustion air thereby preventing the combustion air from blowing out said pilot flame.
  • the inner liner includes, a frusto-conical section converging toward the rear end thereof and a frusto-conical section converging toward the front end thereof; and wherein the outer shell is defined further as being shaped such that the inner liner and the outer shell are coaxially positioned.
  • noise abatement apparatus is defined further as being generally cylindrically shaped, the diameter of the outer periphery of the noise abatement apparatus being sized to be slid into the hollow portion of the inner liner, generally adjacent the rear end of the inner liner.
  • noise abatement apparatus is defined further to include: a plurality of stops, each stop being secured to a portion of the outer periphery of the noise abatement apparatus and extending a distance radially therefrom, each stop engaging a portion of the rear end of the inner liner to position the noise abatement apparatus in an assembled position within the hollow portion of the inner liner.
  • the flame protection apparatus is defined further as extending a distance from the rear end wall generally toward the rear end of the inner liner, the distance being generally between 35 and 40 percent of the distance between the rear end of the inner liner and rear end wall.
