(1) MWSは、一次スチームの圧力に比例してWFI製造量も比例的に増加する。通常、採水運転中はWFI製造量より5～15％多い供給水を送っている。供給水が、次缶に過剰に流れないように蒸発缶底部から次の蒸発缶に入る配管にオリフィスを設け流量を制限している。このオリフィスの孔径を適正に選定することにより、供給水がMWSに過剰に入ったとき、最初に第1蒸発缶で高水位を検出しアラームを出す。第1蒸発缶が高水位になっても、第2蒸発缶以降が高水位にならないように各缶の飽和水出口のオリフィス口径を調整している。各蒸発缶は、底部に覗き窓を設けて飽和水の有無を目視確認出来るようにしている。

(1) WFI production volume increases proportionally to the MWS is proportional to the primary steam pressure. Normal harvest water during operation WFI production quantity 5 ~ has sent 15% water supply. Orifice, restrict the flow pipe enters the evaporator of the next from evaporation can supply water does not flow in excess to the next can make. When supply water into excessive MWS by proper selection of this orifice diameter, 1 evaporation first can detect high water level and the alarm. No. 1 No. 2 evaporator evaporator is a high water level, also adjust the orifice diameter of saturated water outlets of each can avoid high water cans and later. Each evaporator is slid to the bottom, water saturated with or without visual confirmation can have.

(1) MWS is, WFI production volume also proportionally increases in proportion to the pressure of the primary steam. Typically, in water sampling operation are sent 5 to 15% more water than the supplied WFI production volumes. Supply water, I have to limit the flow rate an orifice from evaporator bottom so that it does not flow in excess to the next can in a pipe entering the next evaporator. By properly selecting the diameter of the orifice, when the feed water enters the excess MWS, detects the first high level in the first evaporator to issue an alarm. Even if the first evaporator has a high level, the second evaporation later cans and by adjusting the orifice diameter of the saturated water outlet of each can so as not to high water. Each evaporator is to be able to visually confirm the presence or absence of saturated water provided a viewing window on the bottom.

MWS (1) the proportion of the primary steam pressure is proportional to the increase in the amount of WFI manufacturing. In normal operation, the water is sent to 5 to 15% more than the amount of water supply WFI manufacturing. Water supply, can not flow to the next and enters into the next evaporator from the evaporator bottom portion is provided on the pipe orifice restricts the flow rate. By selecting the proper diameter of the orifice, when the water supply in excess MWS, first in first out of the evaporator with high water level alarm detection. In high water level, a first evaporatorAs the second evaporator in high water level is adjusted by the orifice diameter of the saturated water outlet of the boiler. Each evaporator is provided with an observation window and can be visually confirmed the existence of the saturated water at the bottom.
