PURPOSE: A device for insulating a fuel transfer screw is provided to prevent the fuel from melting when transferring for the rotation and to smoothly supply the fuel to a combusting chamber. CONSTITUTION: A device for insulating a fuel transfer screw comprises a screw pipe(10), a screw, an air cooling housing(30), and a cooling fan. The screw transfers the fuel to the screw pipe from a fuel supply unit(12) and is rotatably installed inside the screw pipe to be inserted into a combusting chamber. The air cooling housing supplies the air to the front end circumference of the screw pipe. The cooling fan supplies the air to an air chamber and cools the circumference connected to the combusting chamber.
