Title: Burning device
Inventor: ISHIKAWA KATSUHIKO
IPC: F23D3/18
Filed: 1989-04-13
Abstract: PURPOSE:To oxidize CO which escaped outside the outer flame tube so as to substantially reduce the CO concentration by providing a catalyzer upwardly extending at least from under the red hot section outside the outer flame tube. CONSTITUTION:The burning is started when the wick 1 is ignited. As the hot burnt gas rises in the burning chamber 8 to cause a thermal draft, the air necessary for the burning is supplied to the burning chamber 8 through air holes 11 in the inner flame tube 6 and outer flame tube 7 as well as through holes 17 in the red hot section 16a to allow a continued burning. The air supplied from the space between the outer flame tube 7 and the outer tube A9 is divided into that which is shown by arrow (a) which is supplied from the air holes 11 in the evaporating section 16b to the burning chamber 8 and that which is shown by arrow (b) which is supplied through a constricted part 15 to an air passage 20. Meanwhile, the fuel evaporated from the wick 1 is carried by the air flow (a) to rise in the burning chamber 8 as shown by arrow (c), and part of it escapes to the control zone 25. However, because there is a catalyzer 24 outside the outer flame tube 7, the unburnt gas which contains CO and escaped to the control zone 25 outside the outer flame tube 27 is oxidized by contacting or passing through the catalyzer 24, resulting in a substantial reduction of the CO concentration.
