ている。The combustor 3 having the above-described configuration is enclosed and housed in a cylindrical case 21. The case 21 has a double structure by a partition wall 22, and the double structure part is surrounded by a partition wall 22 in an annular shape around a combustion part having a combustion pipe 19 and a loop portion 13a of the combustion pipe 13. Passage 23 and the passage connected to the bottom
Forming 24 and. Further, the passage 24 communicates with the combustor 3 side through an opening 26, and the passage 23 is connected through an air supply port 25 to a blower fan (not shown). Further, one of the annular passages 23 is closed by a partition wall 27 at the air supply port 25, so that the combustion air flows only in one direction as shown by the arrow. A partition 28 partitions the space between the passages 23 and 24 so that only the last communication port 29 communicates with the opening 26 side, and the combustion air circulates around the combustion section and is laid horizontally above the bottom of the combustion section. It is configured to be supplied to the center of the annular combustion pipe 19.

It is allowed to pass through, and is heated by exchanging heat with the combustion section through the partition wall 22 and reaches the opening 26 through the communication port 29, and then from the bottom of the combustion section to the central portion of the upper annular combustion pipe 19. It rises and is used for combustion reaction in the combustion tubes 13 and 19.

十分な余熱を行わせることができる。According to the combustion device of the reformer described above, the air passage 23 is formed around the combustion portion of the combustor 3 through the partition wall 22 to form the preheating portion of the combustion air, and thereby the preheating is particularly performed. The combustion efficiency can be improved without providing a vessel. In addition, since the case 21 surrounding the combustion part has a double structure, it has a heat insulating effect, thereby improving thermal efficiency. Also, since it is preheated by the heat energy from the combustion section, it does not require electric power for heating as in the past,
In addition to reducing the operating cost, the combustion air is supplied from the bottom of the combustion section to the center of the upper annular combustion pipe 19 while moving around the circumference of the combustion section for about one round, so that the combustion air is heated. However, it is possible to secure a longer path to guide and to allow sufficient residual heat in the meantime.

Since it has a small hole for combustion,
Combustion air that rises and is supplied to the central portion of the air is blown against the liquid fuel that exits from the small holes, which can accelerate the evaporation of the liquid fuel, thus facilitating the combustion of the liquid fuel. be able to.

のである。As described above, the present invention is a fuel cell reforming apparatus for heating a fuel evaporator by a combustor and converting the fuel vaporized by the fuel evaporator into a reformed gas by a catalyst layer. A laterally-provided annular combustion pipe in which the gaseous fuel flows out and burns, and a plurality of loop-shaped combustion pipes are arranged around the annular combustion pipe and surround the combustion pipe in a loop shape, The loop portion is configured to have a combustion pipe having small holes for flowing out and burning the liquid fuel, and a passage for guiding combustion air to the combustion portion through a partition wall is provided around the combustion portion. With this structure, the combustion air is supplied from the bottom of the combustion section to the central portion of the laterally provided annular combustion pipe above the passage while rotating around the circumference of the combustion section. It has an excellent effect.

力等を運転コストの低減を図ることができる。That is, since the passage for guiding the combustion air to the combustion portion via the partition wall is provided around the combustion portion, the combustion air can be preheated by the passage, and therefore, the special preheater can be omitted. The combustion air can be preheated, whereby the installation space and power consumption of the originally installed preheater can be reduced to reduce operating costs.

ことができるため、高い燃焼効率を得ることができる。Moreover, the passage for guiding the combustion air to the combustion section is configured such that the combustion air is supplied from the bottom of the combustion section to the central portion of the annular combustion pipe that is installed above the combustion section around the periphery of the combustion section. Therefore, it is possible to secure a longer path for guiding the combustion air while heating it, and the combustion air can provide sufficient residual heat during that time, so that high combustion efficiency can be obtained.

By providing a small hole for evaporating and burning the air, combustion air rising to the center of the annular combustion pipe blows against the liquid fuel flowing out from the small hole, and therefore the liquid fuel The evaporation is promoted, and the combustion efficiency of the liquid fuel can be increased.
