Definitions

  • This invention relates to a liquid fuel burner adapted to make variable the rate of gasification of a liquid fuel, such as kerosene, sucked up by a wick, thereby facilitating the adjustment of the rate of combustion of fuel.
  • a liquid fuel such as kerosene
  • the wick type liquid fuel burner of conventional kerosene.stove or the like is so arranged that the top of the wick is projected between inner and outer flame cylinders so that changing the projection height of the wick makes variable the rate of gasification of fuel from the wick, thereby adjusting the rate of combustion of fuel.
  • an excessive decrease in the projection height of the wick accelerates the deposition of tar on the wick or increases the CO content of exhaust gases, so that actually it has been impossible to substantially adjust the combustion rate.
  • the recent worsening of the condition of oil supply has come up with kerosene containing heavier fractions, which means that the kerosene now available has a wide range of boiling point and contains large amounts of high-boilihg substances.
  • the wick temperature can hardly be elevated during the dry burning because of the amount of air supply being limited by the decreased diameter of air-holes formed in the inner and outer flame cylinders adjacent to the wick to reduce the amount of CO emission and odor while stable combustion is obtained from ignition.
  • the deposited tar cannot be eliminated.
  • the present invention has for its object the provision of a liquid fuel burner wherein at least one of the inner and outer flame cylinders is provided at its lower end with a removable cylindrical body having a large number of air holes for facilitating the adjustment of the combustion rate.
  • an outer wick cylinder 3 is installed through a packing 2 above a top opening in a fixed tank 2 which stores xxxxxxxxxx kerosene used as an example of liquid fuel.
  • a wick guide cylinder 4 which vertically movably carries on its xxxxx periphery a cylindrical wick 5.
  • the wick 5 serves to suck up xxxxxxxxxxxxx kerosene in the fixed tank 1 and gasify it.
  • the upper portions of the outer wick cylinder 3 and wick guide cylinder 4 terminate in fire tray portions 6 and 7, respectively, on which is mounted a combustion cylinder assembly 14 comprising an outer flame cylinder 8, an inner flame cylinder 9, an outer cylinder 10, a substantially hemisphere-like a coil 12 and a partition plate 13 in the form of a disk.
  • the outer flame cyln- der 8 and inner flame cylinder 9 are each formed with a number of air holes 15. The air which flows in through the air holes 15 and gasified xxxxxxxxxxxxxxx kerosene from the top of the wick 5 are mixed together. and the mixture is burned in a combustion chamber 16 defined between the outer and inner flame cylinders 8 and 9.
  • the inner and outer flame cylinders 9 and 8 of said combustion cylinder assembly 14 have inner and outer flame cylindrical bodies 17 and 18, respectively, removably fitted to their lower ends, as shown in Fig. 2.
  • the inner flame cylindrical body 17, as shown in Fig. 3 is formed with a number of air holes 19.
  • the total area of these air holes 19 is larger than that of the air holes 15 in the lower portion of the inner flame cylinder 9 having the same height as the height A of the inner flame cylindrical body 17.
  • the outer flame cylindrical body 18 is also formed with a number of air holes 20, as shown in Fig. 4.
  • the total area of these air holes 20 is larger than that of the air holes 15 formed in the lower portion of the outer flame cylinder 8 having the same height as the height A of the outer flame cylindrical body 18.
  • the inner and outer flame cylindrical body 17 and 18 have the lower ends of the inner and outer flame cylinders 9 and 8 force-fitted thereto, but such connections may be of thread or bayonent type. In any case, it is preferable that there be no protrusion in the interior of the combustion chamber 16, in order. to prevent disturbance of combustion and degradation of material.
  • this liquid fuel burner is used with the inner and outer flame cylindrical bodies 17 and 18 removed, as shown in Fig. 1 or with these inner and outer flame cylindrical bodies 17 and 18 mounted, as shown in Fig. 2.
  • the overall height of the combustion cylinder-assembly 14 changes and so does the draft in the combustion chamber 16; accordingly, the combustion rate increases or decreases. That is, it is possible to adjust the combustion rate.
  • the flow rate of air in the vicinity of the wick 5 can be changed by mounting or dismounting the outer and inner flame cylindrical bodies 18 and 17, various kinds of kerosene can be burned more completely.
  • the inner and outer flame cylindrical bodies 17 and 18 having air holes 19 and 20 of large total opening area are used as in this embodiment, mounting them increase the amount of inflow of air adjacent to the wick 5, accelerates combustion adjacent to the wick 5, elevates the temperature of the wick 5, and makes it easier to eliminate the tar deposited on the wick 5. As a result, even if the deposition of tar has made it impossible to use the wick any further as in the past, it can be revived by performing the dry burning with a supply of xxxxxxxxxxxx kerosene cut off.
  • the inner and outer flame cylinderical bodies 17 and 18 should be as inexpendisve as possible, and their height should be as small as possible. However, they should be tall enough to rise above the top of the wick 5 in its projected position so as not to substantially influecne combustion. That is, if the inner and outer flame cylindrical bodies 17 and 18 are tall enough to rise above the top of the wick 5 in its projected position, there will be a merit that even if a clearance is created in the junction between the inner and outer flame cylindrical bodies 17 and 18 and the inner and outer flame cylinders 9 and 8 of the combustion cylinder assembly 14, this will not substantially influence combustion.
  • Fig. 5 shows another embodiment of the invention xxxxxxxxxxxxxxx , wherein the inner and outer flane cylinders 9 and 8 are divided into upper and lower per- tions, the lower portions serving as the inner and outer flame cylindrical bodies 17 and 18, respectively.
  • the addition of the inner and outer flame cylinders to the inner and outer flame cylindrical bodies 17 and 18 will cause no impression of incompatibility since the inner and outer flame extensions 17 and 18 are surrounded with the outer cylinder 10, and there is also a merit that combustion is not substantially influenced by the wind.
  • Figs. 6 and 7 show other embodiments of the invention, wherein only the outer flame cylinder 8 or the inner flame cylinder 9 is divided into upper and lower portions.
  • the intended merit can-be obtained by changing the lower air hole area in only one of the inner and outer flame cylinders 9 and 8.
  • the draft in the combustion chamber can be changed by mounting and dismounting the inner and outer flame cylindrical bodies, it is possible to adjust the rate of combustion by changing the rate of gasification of fuel without having to change the projection height of the wick.
  • the mounting and dismounting of the inner and outer flame cylindrical bodies changes the flow rate of air adjacent to the wick, so.that at least two kinds of liquid fuels can be burned completely.
