Claims

[Scope of utility model registration request]

(1) A fuel guide path that penetrates the wall of the combustion furnace and opens into the combustion chamber of the combustion furnace in order to guide fuel into the combustion furnace, and at least a portion of the guide path that penetrates the wall. A fuel supply to a combustion furnace, characterized in that a cooling passage extending along the axis of the guide passage and communicating with a coolant inlet and a coolant outlet is formed around the guide passage. Device.

(2) The precursor cooling passage is closed at a portion corresponding to the open end of the fuel guide passage, and the cooling liquid passage extends within the cooling passage at intervals from each other along the axial direction thereof, and the cooling liquid passage extends at the closed end of the cooling passage. A pair of partition members spaced apart from each other divides the cooling liquid into an outgoing path between the partition members, in which the cooling liquid inlet is open, and a return path, in which the cooling liquid outlet is open.
The fuel supply device according to claim 1 of the utility model registration claim.

(3) The coolant passage is closed at a portion corresponding to the open end of the fuel guide passage, and the coolant passage extends within the cooling passage along its axial direction and is spaced from the closed end. A registered utility model, wherein a tubular partition member divides the cooling liquid into an outgoing path inside the partition member, where the cooling liquid inlet is open, and a return path outside the partition member, where the cooling liquid outlet is open. A fuel supply device according to claim (1).

(4) The fuel supply device according to claim (1), wherein the guide path and the coolant passage each have a circular cross-sectional shape.

(5) The fuel supply device according to claim (1), wherein the guide path and the coolant passage each have a rectangular cross-sectional shape.

(6) The fuel supply device according to claim (1), wherein the guide path is inclined with the open end facing downward.
