Abstract
Description
1)組立品のバッチ生産が可能であり、コストの削減ができる。
2)単一組立品が炉外で高温効力試験が実施できる。
3)組立品ごとに複数のマルチスタット螺旋管で形成された螺旋柱面により構成され、分離式配置構造がコンパクト化されていないという欠陥を改善し、また、螺旋管曲率半径が小さいため、構造の安定化ができ、流動励起振動が起こりにくくなり、支持構造が簡易かつ信用できるようになる。
4)螺旋管の最小曲率半径は、現在動作中の検査器具の接近性により選出し、各組立品の伝熱管がヘッダを設置せずに、同一の液体ヘッダと蒸気ヘッダに連結され、体積と表面の動作中検査ができる。また、管が詰められた際、1つのモジュールではなく、管一本だけを塞げばよく、伝熱管の最大利用率を維持できる。
5)固定オリフィス板と取り除き可能なオリフィス板というデザインは、管が詰められた後の流量再配分を簡単に行うようにする。
