この個所において溶接部の施工欠陥により過去に度々問題が発生している。もし加熱部の胴部に腐食もしくは溶接による欠陥が出た場合、一次スチームとピュアスチームとの交差汚染が直ちに生じるリスクがある。対策として、図3や図4のように熱交換部を蒸発室外部に設ける設計により品質リスク低減を計っている機種もある。また、図2の場合は蒸発部胴板と仕切円筒の間の表面状態を点検出来ずGMP上好ましくない構造である。さらに、熱交換部（一次スチーム側）を蒸発室の内部に組み込む方式は蒸発缶の全長が長くなり、MWSの据付け高さが高くなることが難点である。

In this place by construction defects in the weld in the past often raised problem. If there is a risk if you came out due to corrosion or weld defects in the heating of the body of the primary steam and pure steam and cross-contamination occur immediately. The design as shown in Figure 3 and Figure 4 heat exchanger placed evaporator with external clocking quality risk models. Also, could not check the evaporation of body Board and transfer cylinder between surface condition figure 2 If the GMP preferably on no structure. Method, heat-exchanger (primary steam side) into the Interior of the evaporation Chamber is longer overall length of the evaporator, in can be the installation height of the MWS.

Often a problem in the past has been caused by construction defects in welds in this point. If defective due to corrosion or welded to the body portion of the heating portion is out, there is a risk of cross-contamination between the primary steam and pure steam immediately occur. As a countermeasure, there is also models that measure the quality risk reduced by design to provide a heat exchanger in the evaporation chamber externally as shown in Figure 3 and Figure 4. Also, a GMP undesirable structural can not check the surface condition between the evaporating section and the partition plate cylinder cylinder case of FIG. In addition, a method of incorporating a heat exchange unit (primary steam side) in the interior of the evaporation chamber the longer the total length of the evaporator, a disadvantage that the installation height of the MWS is high.

The construction of welding defects in this area in the past, many problems have occurred. If the heating section of the body that defects due to corrosion or welding, and steam is generated immediately after the risk of cross contamination and pure steam. As a countermeasure, as shown in Fig. 4 and Fig. 3 is a measure of quality risk reduction on the heat exchange portion provided on the outside of the evaporation chamber by the model. In addition, in the case of Fig. 2 and the evaporation portion of the partition plate, the surface condition of the cylinder between the inspection could not be GMP on structure. In addition, theSteam heat exchange unit (primary) in the interior of the evaporation chamber into the system, the overall length of the evaporator is increased, and the rise of the installation height of the MWS.
