摘要： PURPOSE:To contrive uniformalization of concentration of the fuel and air mixture, and reducing of the burning noise by a simple structure of the title device by a method wherein a primary air duct is provided to be formed into an opening for a vaporizing chamber, atomizing nozzles and liquid fuel supplying pipes are provided inside of said duct with spacing at designated intervals respectively. CONSTITUTION:A vaporizing chamber 3 is formed by being enclosed with a vaporizing wall 2 which is preheated by a heater 1, a primary air duct 6 is provided with fixing its one end to said vaporizing wall 2. An atomizing nozzle 4 for blowing out the primary air at high speed is provided facing to inside of said duct 6. Further, a fuel supplying port 5a cut at an acute angle at the tip end of a liquid fuel supplying pipe 5 is provided facing to the central part inside of said nozzle 4. The caliber of said nozzle 4 is minimized within non-interference range for atomizing, and the caliber of said duct 6 is maximized to the extent the uniformity of concentration of mixture does not occur, while the flowing air speed in said duct 6 is kept slower than the speed at said nozzle 4. Thereby, uniformalizing of concentration of the mixture can be obtained by the simple structure, also reducing of the burning noise can be achieved.
