関して問題を有していた。Structure and problems of conventional examples Conventionally, this type of reaction has been mainly carried out industrially.
The equipment also incorporates a reformer as part of a large plant. In general, in either the steam reforming reaction using hydrocarbon gas and steam or the partial oxidation method using air, the reforming process is carried out after sufficiently preheating the hydrocarbon gas, water (i.e. steam, or air). There is peace of mind in supplying the foaming catalyst. For this reason, large-scale plants use a method in which high-temperature, high-pressure steam and air are created using a separate heat source such as a heater, and then mixed with hydrocarbon gas and preheated. The above method cannot be used in a reformer for home use or small-scale industrial use, such as the present invention, because the device itself needs to be as compact as possible. Can not. For this reason, it is necessary to effectively utilize the heat within the reforming device, but conventional devices have had problems in this regard.

。Next, the operation of this device will be described. In particular, partial combustion of natural gas will be described as an example. Natural gas and air, which have been mixed in advance at a stoichiometric ratio (m = 1.4 to 1.2) using a mixer (not shown), are supplied from the mixed gas supply pipe 2 to the reaction tube 1 and the inner tube 4. The gas that passes through the formed passage, further passes through the outside of the numerous cylindrical tubes 6 of the present invention, passes through the passage formed by the circular tube 4 and the inner tube B, and then passes through the burner port plate 8. It is ignited by the spark plug 9, and a flame is formed on the flame port plate 8.
