Abstract
【解決手段】分解ガスを冷却するための熱交換器は、熱交換管1、管板2、3、外被4、各1つの分解ガス給排用端室5、6を備えている。熱交換器内部空間は隔壁7によって、分解ガスの流れ方向で前後する2つの部分空間8、9に分割されており、これら部分空間はそれぞれ独自の冷却媒体供給短管10、18及び排出短管11、19を備えている。分解ガスのガス流入側にある部分空間8は沸騰水を流通させる。この部分空間は供給管路13及び排出管路15を介して水/蒸気ドラム12と結合されている。分解ガスのガス流出側にある部分空間9は給水を流通させる。部分空間9は排出管路21を介して水/蒸気ドラム12と結合されている。両方の部分空間8、9の間の隔壁は熱交換器の内部を流れる冷却媒体の通過に対して透過性である。
