は、顕熱を燃焼室４の反応部２ａへ伝熱させることにより、熱回収ができる。 Is, by transferring heat to sensible heat to the reaction section 2a of the combustion chamber 4, it is heat recovery. この際、改質ガスＲＧは、改質室２の出口で温度が下がるが、反応部２ａの出口となる仕切壁８の付近で最高温度となって完全に改質されるため、改質されたガスは再び元のガスに戻ることはない。 In this case, the reformed gas RG is temperature drops at the outlet of the reforming chamber 2 completely because the reformed reformed becomes maximum temperature near the partition wall 8 to be the outlet of the reaction section 2a the gas is not able to return to the original gas again.
【００１４】上記改質反応を行うときの改質室２及び燃焼室４の温度プロフィルは、図１の（ロ）に示すようになることが実験により確認された。 [0014] Temperature profile of the reforming chamber 2 and the combustion chamber 4 when performing the reforming reaction, that is as shown in the (b) Figure 1 was confirmed by experiments. 曲線Ｉは燃焼室４内のガスの温度を示し、曲線IIは改質室２内のガスの温度を示す。 Curve I represents the temperature of the gas in the combustion chamber 4, a curve II represents the temperature of the gas in the reforming chamber 2. 図１の（ロ）から明らかなように、改質室２内のガスは改質室２の反応部２ａと熱交換部２ｂとの間の仕切壁８の付近で最高温度となり、このとき、燃焼室４ As is clear from the (B) 1, gas reforming chamber 2 becomes the maximum temperature in the vicinity of the partition wall 8 between the reaction section 2a and the heat exchanging portion 2b of Aratameshitsushitsu 2, this time, combustion chamber 4
内のガスも燃焼室４の反応部４ａと熱交換部４ｂとの間の仕切壁９の付近で最高温度になり、温度分布のピーク位置が一致することがわかる。 Gas inner becomes the maximum temperature near the partition wall 9 between the reaction section 4a and the heat exchanger portion 4b of the combustion chamber 4, it is seen that the peak position of the temperature distribution coincide.
【００１５】上記において、改質室２と燃焼室４は、反応部２ａと４ａの位置を互いにずらして、これらの出口側にだけ熱交換部２ｂと４ｂを形成するようにしてあることから、全体をコンパクトにすることができる。 In the above, since the reforming chamber 2 and the combustion chamber 4, which by shifting the position of the reaction section 2a and 4a to each other, are so as to form a heat exchanging portion 2b and 4b only those on the outlet side, it can be a whole compact. 又、 or,
上記熱交換部２ｂと４ｂには熱伝達係数の大きいアルミナボール１０がそれぞれ充填してあるので、高価な改質用触媒１や燃焼用触媒３の使用量を低減することができ、特に、燃焼用触媒３は改質室２の熱交換部２ｂから顕熱を受けるので高温側と低温側との温度差が小さくなり、このため、作動温度を低くできることにより寿命を延ばすことができる。 Since the above heat exchange section 2b and 4b are filled respectively larger alumina balls 10 of the heat transfer coefficient, it is possible to reduce the amount of expensive reforming catalyst 1 and the combustion catalyst 3, in particular, the combustion use catalyst 3 temperature difference between the hot and cold sides are also subject to the sensible heat from the heat exchange unit 2b of the reforming chamber 2 is reduced, and therefore, it is possible to extend the life by be lowered operating temperatures.
