ど伸びない。(Problems to be Solved by the Invention) By the way, the conventional reaction tube 2 described above uses a heat-resistant alloy tube made of high nickel high chromium steel manufactured by centrifugal casting, and the reforming catalyst 5 is made of alumina or the like. A particulate material in which nickel is added to a ceramic base material is used. The material of this reaction tube 2 has a higher coefficient of linear expansion than the material of the reforming catalyst 5, and while the reaction tube 2 extends in the radial and axial directions while heat is being applied, the reforming catalyst 5 hardly grows.

停止が繰返される度に発生する。Therefore, during heating, the reforming catalyst 5 sinks into the lower region of the reaction chamber 3 by the amount that the reaction tube 2 extends and the volume of the reaction chamber 3 expands. When the operation of the fuel reformer is stopped in this state, as the temperature drops, the reaction tube 2 shifts to a contraction operation, thereby tightening the reforming catalyst 5 in the reaction chamber 3 radially inward. . Therefore, the particles of the reforming catalyst 5 are cracked and powdered. This phenomenon occurs when the fuel reformer starts up,
Occurs every time the outage is repeated.

障や異常を引き起こすという問題が生じる。When the particles of the reforming catalyst 5 are broken and powdered, the fragments and powder of the catalyst are carried by the produced gas flow and flow into the produced gas distribution chamber 12.
Problems arise in that they may enter the chamber and adhere to the walls of the chamber, or they may adhere to downstream piping, valve equipment, etc. after being discharged outside the device, causing malfunctions or abnormalities.

We provide a fuel reformer that prevents fuel from entering and adhering to the chamber walls, or from adhering to downstream piping, valve equipment, etc. after being discharged outside the device, and causing failures or abnormalities. It's about doing.

である。(Means for Solving the Problems) In order to achieve the above object, the present invention provides a container, a burner for supplying combustion gas into the container, and an outer tube and an inner tube arranged vertically in the container. a reaction tube arranged concentrically to form a double tube and equipped with a cap at the top; a reaction chamber formed between the outer tube and the inner tube; and a reaction chamber filled with the reactant. The reforming catalyst is supplied into the container and rises in the reaction chamber, and is fed to the catalyst at the top of the reaction tube.
In a fuel reformer, the raw material gas that reverses after colliding with the knob and descends inside the inner tube is reformed by exchanging heat with the combustion gas in the rising process inside the reaction chamber. A plug pipe is disposed inside the pipe, the upper end of which is open concentrically with the inner pipe, and the lower end is closed. The present invention is characterized in that a baffle body including an extension portion extending from the edge of the opening toward the inside of the opening of the plug pipe is provided.

The plug enters the inside of the baffle body, descends inside the plug pipe along the extension extending toward the inner part of the plug pipe, then rises again, and passes through the gap between the extension of the baffle body and the plug pipe. It flows out of the tube and then descends between the plug tube and the inner tube and is discharged out of the device. Therefore, even if the raw material gas entering the plug pipe from the opening in the middle of the baffle body contains fragments or powder of the reforming catalyst, these will be absorbed into the lower region of the plug pipe when they enter the plug pipe. These debris and powders do not flow downstream.

であり、これは吸熱反応である。この反応を右に促進さ
せるためには外部から熱を供給しなければならない。By the way, since the reaction chamber 3 is filled with a reforming catalyst 5, the raw material gas is reformed while rising there. This reforming reaction is CH4+H20≠CO+3H2 -49,27Kcal/gaol, and is an endothermic reaction. To accelerate this reaction, heat must be supplied from the outside.

Fuel is supplied from the fuel supply port 18 and air is supplied from the air supply port 19, and these are mixed and burned within the burner 17. Then, this combustion gas enters the combustion gas distribution chamber 10 and descends there. During this descent, after exchanging heat with the raw material gas (indicated by a solid line) rising in the reaction chamber 3, it is discharged from the combustion gas outlet 11.

取除かれることになる。According to this embodiment, the plug pipe 20 whose upper end is open is disposed inside the inner pipe 2b, and the baffle body 21 configured as described above is attached to the upper end of the inner pipe 2b. The raw material gas will once flow into the plug pipe 20 through the opening 21g of this baffle body 21, so even if fragments or powder of the reforming catalyst 5 are mixed in the raw material gas, these will be absorbed by their own weight. The plug naturally falls into the plug pipe 20 and is removed.

Therefore, the fragments and powder of the reforming catalyst 5 will not flow downstream, and will not adhere to the walls of the produced gas distribution chamber 12 or to downstream piping, valves, equipment, etc. outside the device. It is possible to prevent such adverse effects.

たりする等の弊害を防止することができる。As is clear from the above description, according to the present invention, a plug pipe is disposed inside the inner pipe, the upper end of which is open concentrically with the inner pipe, and the lower end is closed, and the inner pipe is provided at the upper end of the inner pipe. Since the baffle body is provided with an extension portion extending radially inward, opening in the middle thereof, and extending from the edge of the opening toward the inside of the opening of the plug pipe, fragments of the reforming catalyst are contained in the raw material gas. Even if powder or powder is mixed in, these will naturally fall into the plug pipe due to their own weight and be removed, and will not be mixed into the raw material gas flowing downstream, and will not adhere to the walls of the produced gas distribution chamber. It is possible to prevent harmful effects such as adhesion to downstream piping, valves, equipment, etc. outside the device.
