Definitions
- This invention pertains to the combustion of fuels and other vaporizable and combustible substances.
- the invention provides novel means for the combustion of fuels and other substances, preferably at relatively high heat releases, and particularly apparatus for changing the state of aggregation of combustibles and vaporizable substances and distributing them to assure more complete combustion.
- the invention is applicable to a wide variety of uses such as disc, grid or ring burners, gas turbine systems, fluid heaters, rocket or jet propulsion devices, vapor generators, fog dispelling apparatus and apparatus for drying, smelting, sintering or baking.
- Apparatus of the invention through the distribution of the combustibles or vaporizable substances, fiame dispersion and apportionment obtainable therewith, permits furnaces or other devices of which it is a part to be of more compact construction and lighter weight than hitherto practicable.
- Apparatus embodying and for carrying out the invention comprises one or more combustion chambers provided with means to facilitate vaporization, gasification, raising to or'beyond fire point, or otherwise greatly increasing the combustibility and potential combustion speed of fuel oil or other combustible or vaporizable substance fed into the stream of gases of combustion around or beyond the combustion chamber proper 'of a furnace.
- Furnaces suitable for the purpose are disclosed in our copending applications Serial No. 479,010 filed March 13, 1943, now Patent Number 2,500,925, issued March 21, 1950; Serial No. 506,670, filed October 18, 1943, now Patent Number 2,569,446, issuedOctober 2, 1951 and Serial No. 509,080 filed November 5, 1943, now Patent Number 2,464,791, issued March22, .1949.
- combustion chambers of many types other than those disclosed in these copending applications may be used to carry out the invention, the furnaces disclosed therein have the advantages of requiring but a relatively small space and of being of a minimum weight.
- the substance to be burned or vaporized is introduced into contact with the stream; of gases produced in the combustion chamber-of a furnace preferably by nozzles connected to a mani fold, as disclosed in our copending application Serial No. 509,080, filed November 5, 1943, or through injectors at the combustion chamber exit. If the substance is in a liquid or solid state, it is vaporized or otherwise prepared for high speed combustion either by the hot gases 1 nace, by contact with adjacent parts of the furnace which have'become heated by gases,
- the injectors which may be heated from the combustion chamber, or by distributing apparatus beyond the combustion chamber throat which is heated to a high degree. Any one or more of these methods of vaporization may be used. After vaporization of the substance and its mixture with gases of combustion, the mixture is ejected, preferably at high velocities, through the exit nozzles of distributing devices.
- Relatively high air pressure is employed in the combustion chamber windbox to serve the function of (l) furnishing oxygen for combustion; (2) supplying sufficient force to intermix the substance or substances raised to or beyond the fire point or otherwise prepared for virtually instantaneous ignition; (3) distributing the mixture of substances'to individual nozzles of a distributing device; (4) maintaining a high velocity through these nozzles; and (5) aspirating surrounding air .by the gas-vapor issuing from the nozzles.
- Localization of the aspirating efiect may be obtained by using hollow rings or polygonal-shaped registers around individual distributing devices, around a group of distributing devices or around a single nozzle of a distributing device.
- the distributing devices may be entirely enclosed by air ducts or have air ducts positioned on one or more sides thereof.
- Perfection of these devices will depend upon the optimum proportioning of the parts to assure maximum advantages from all of these variables.
- the spacing and the arrangement of the nozzles of the distributing devices, as well as their free areas, are important considerations. Also optimum proportioning of air admitted to, around, or alongside the nozzles is desirable, lest the quantity or velocity either be inadequate or plethoric which would result in incomplete oxidation, blowing out, or undue dilution of the stream from the nozzles.
- Regulation of air flow surrounding the nozzles is a, matter of importance in connection with lighting oil the mixture of gas and air at the face or faces of the distributing devices. It is frequently desirable temporarily to halt or greatly to diminish air flow while initial ignition is being secured, then to advance it to support increased flow rates and combustion speed.
- Substances may be employed for feeding the distributor of distributing devices although satisfactory results can be secured through the use of the same material as that used for firing the combustion chamber.
- Another important consideration is the apportionment of the injectors used to supply the substances to be vaporized, raised beyond the fire point or otherwise prepared for high speed combustion, either to the combustion chamber or the distributing devices of the present invention, since the rate of flow from the nozzles depends uponsuch apportionment as well as upon the area of the nozzles and speed of travel of the mixture expelled from the combustion chamber exit.

This invention pertains to the combustion of fuels and other vaporizable and combustible substances.
The invention provides novel means for the combustion of fuels and other substances, preferably at relatively high heat releases, and particularly apparatus for changing the state of aggregation of combustibles and vaporizable substances and distributing them to assure more complete combustion. The invention is applicable to a wide variety of uses such as disc, grid or ring burners, gas turbine systems, fluid heaters, rocket or jet propulsion devices, vapor generators, fog dispelling apparatus and apparatus for drying, smelting, sintering or baking. Apparatus of the invention, through the distribution of the combustibles or vaporizable substances, fiame dispersion and apportionment obtainable therewith, permits furnaces or other devices of which it is a part to be of more compact construction and lighter weight than hitherto practicable.
Apparatus embodying and for carrying out the invention comprises one or more combustion chambers provided with means to facilitate vaporization, gasification, raising to or'beyond fire point, or otherwise greatly increasing the combustibility and potential combustion speed of fuel oil or other combustible or vaporizable substance fed into the stream of gases of combustion around or beyond the combustion chamber proper 'of a furnace. Furnaces suitable for the purpose are disclosed in our copending applications Serial No. 479,010 filed March 13, 1943, now Patent Number 2,500,925, issued March 21, 1950; Serial No. 506,670, filed October 18, 1943, now Patent Number 2,569,446, issuedOctober 2, 1951 and Serial No. 509,080 filed November 5, 1943, now Patent Number 2,464,791, issued March22, .1949. Although combustion chambers of many types other than those disclosed in these copending applications may be used to carry out the invention, the furnaces disclosed therein have the advantages of requiring but a relatively small space and of being of a minimum weight. The substance to be burned or vaporizedis introduced into contact with the stream; of gases produced in the combustion chamber-of a furnace preferably by nozzles connected to a mani fold, as disclosed in our copending application Serial No. 509,080, filed November 5, 1943, or through injectors at the combustion chamber exit. If the substance is in a liquid or solid state, it is vaporized or otherwise prepared for high speed combustion either by the hot gases 1 nace, by contact with adjacent parts of the furnace which have'become heated by gases,
- by'the injectors which may be heated from the combustion chamber, or by distributing apparatus beyond the combustion chamber throat which is heated to a high degree. Any one or more of these methods of vaporization may be used. After vaporization of the substance and its mixture with gases of combustion, the mixture is ejected, preferably at high velocities, through the exit nozzles of distributing devices. Relatively high air pressure is employed in the combustion chamber windbox to serve the function of (l) furnishing oxygen for combustion; (2) supplying sufficient force to intermix the substance or substances raised to or beyond the fire point or otherwise prepared for virtually instantaneous ignition; (3) distributing the mixture of substances'to individual nozzles of a distributing device; (4) maintaining a high velocity through these nozzles; and (5) aspirating surrounding air .by the gas-vapor issuing from the nozzles. Localization of the aspirating efiect may be obtained by using hollow rings or polygonal-shaped registers around individual distributing devices, around a group of distributing devices or around a single nozzle of a distributing device. The distributing devices may be entirely enclosed by air ducts or have air ducts positioned on one or more sides thereof.
Perfection of these devices will depend upon the optimum proportioning of the parts to assure maximum advantages from all of these variables. The spacing and the arrangement of the nozzles of the distributing devices, as well as their free areas, are important considerations. Also optimum proportioning of air admitted to, around, or alongside the nozzles is desirable, lest the quantity or velocity either be inadequate or plethoric which would result in incomplete oxidation, blowing out, or undue dilution of the stream from the nozzles. Regulation of air flow surrounding the nozzles is a, matter of importance in connection with lighting oil the mixture of gas and air at the face or faces of the distributing devices. It is frequently desirable temporarily to halt or greatly to diminish air flow while initial ignition is being secured, then to advance it to support increased flow rates and combustion speed. Substances, whether liquid or solid, or in any other state of aggregation, may be employed for feeding the distributor of distributing devices although satisfactory results can be secured through the use of the same material as that used for firing the combustion chamber. Another important consideration is the apportionment of the injectors used to supply the substances to be vaporized, raised beyond the fire point or otherwise prepared for high speed combustion, either to the combustion chamber or the distributing devices of the present invention, since the rate of flow from the nozzles depends uponsuch apportionment as well as upon the area of the nozzles and speed of travel of the mixture expelled from the combustion chamber exit.
The invention will be understood from'thefoilowing description when considered in connection with the accompanying drawings forming a part thereof and in which:
Fig. 1 is an isometric view, partly broken away,
of apparatus embodying the invention, and
Fig. 2 is an enlarged cross-sectional view taken on line 2-2 of Fig. 1.
Like characters of reference refer to the same or to similar parts throughout the several views.
A preferred fuel distributor ring is disclosed in Figs. 1 and: 2 In this form', a distributing ring Hi is enclosed: in an annular air duct '17. Outside the duct II and adjacent the distributing ring: 16,. is a supplementary annular air duct '58 of substantially the same diameter as" the ring 16. The duct 11 has tubular cross-arms or chordal members T9 and 80 extending diametrically through its central space, the cross-arms interseatin and in communication with each other and in communication with the duct 71 at opposite ends thereof. The distributing ring T6 has cross arms or chordal members 8! similar to the cross: arms T9 and at; which extend inside the cross arms T9 and. 89, while the supplemental air distributing ring 13 has cross arms or chordal members 82 similar to the cross arms 19 and 80, which. extend? outside the cross arms of the duct 11 and adjacent to the cross arms at. The duct H- has a plurality of circumferentially spaced nozzles 83 on one side thereof and plurality of diametrically spaced nozzles 84 on the cross arms is and 89. As shown more clearly in Fig. 2, the ring 15 has a plurality of nozzles 85 in alignment with nozzles 83 and in. communication therewith. The nozzles 85 have air inlets 88 through which air from. the air conduit 11 enters the nozzles. The cross arms 82 have nozzles similar to the nozzles 85 in alignment with the nozzles 84 and in communication therewith. The supplemental air duct 18 has a plurality of nozzles 81, each of which is in alignment with nozzles 85 and in communication therewith. The cross arms 82 of the ring l8 have nozzles in alignment and in communication with the nozzles in the cross arms 8|. Air under pressure enters the duct 11 through the conduit 90 and enters the supplemental air duct 18 through the conduit 89, while the mixture of air and substances such as issues from the blower or compressor I3, fuel feed line 25, wind box 3-, fuel atomizer conduit atomizer 2'9, enters the distributor ring 16 through the inlet conduit 88. With the arrangement of air ducts and distributor ring disclosed in this form of the invention, exceedingly short, fast burning flames, which may be termed supercharged, are obtained. While the cross arms 19, 80, SI and 82 may be omitted if desired, these arms will be of utility in certain types of turbines. The forms of the invention shown in Figs. 1 and 2, may be con- 509,080, but firing gasified or largely gasified fuel oil instead of atomized fuel oil and, at the same time, possessing means by which individual furnaces or the streams of gas to the individual furnaces may be secured.
Certain of the nozzles are provided with fins 93.
In operation, the gasified fuel discharged by nozzles 85 is supercharged by air passing through the nozzles 81' from the air line 18, the flame is ejected into the furnace formed by the finned trusto-conical air directing members 85 between which air fromthe conduit 77 passes through the annular passages 86 into the gas power outlet 83.
The invention disclosed herein may be manufactured and used by or for the Government of the United States for governmental purposes without payment of royalty thereon.
