PURPOSE:To reliably recover kerosene during non-firing, by a method wherein one end of a fuel drain pipe is positioned in the vicinity of an outer cylinder, and a drain cup provided with a fuel leak preventing means is inserted into the other end of the fuel drain pipe. CONSTITUTION:When a motor 31 runs, an evaporating cylinder 17 simultaneously turns, and kerosense is fed through a kerosene piping 19 to jet it through an injection nozzle 34. The jetted kerosense flows in the evaporating cylinder 17 through a drain port 35 by a centrifugal force, it is evaporated therein to jet it through an injection nozzle 36, and the kerosene is burnt at a burner case 16. During non-firing, kerosene is jetted through the injection nozzle 34 for a specified time and is jetted out through the drain port 35 and the injection nozzle 36, and drops from a communictaing port 20 to gather around a motor support 21. The gathered kerosene flows through a fuel drain pipe 23 from a drop port 24, and flows to a contant fuel level device through a fuel drain port 29. |
