Description
【考案の詳細な説明】
この考案は、上下管寄せを多数の木管で連通した多管式
貫流ボイラにおける罐内腐食状態観察装置に関するもの
である。[Detailed description of the invention] This invention relates to an apparatus for observing the state of corrosion inside a can in a multi-tube once-through boiler in which the upper and lower headers are connected through a large number of wooden tubes.
多管式貫流ボイラにおいて、水処理が不適当であると、
下部管寄せ等にピッチング等の腐食が発生する。In a multi-tubular once-through boiler, if water treatment is inadequate,
Corrosion such as pitting occurs on the lower header, etc.
これは、給水中に含まれている溶存酸素等が原因で゛あ
る。This is caused by dissolved oxygen, etc. contained in the water supply.
そこで従来においては、検査孔等から内部を覗いて腐食
状態を推定していた。Conventionally, therefore, the state of corrosion was estimated by looking into the interior through an inspection hole or the like.
ピッチングの深さ等は測定することができなかった。It was not possible to measure pitching depth, etc.
この考案は、管寄せと同質材料から戊る試験片を下部管
寄せ内へ挿入配置しておき、この試験片を観察すること
によって、罐内の腐食状態を推定できるようにしようと
するものである。This idea aims to make it possible to estimate the state of corrosion inside the can by inserting a test piece made of the same material as the header into the lower header and observing this test piece. be.
ピッチングの深さ等も、この試験片を測定することによ
って、推定できるようにしようとするものである。The depth of pitting and the like can also be estimated by measuring this test piece.
以下この考案の実施例を図面にもとづいて説明する。Examples of this invention will be described below based on the drawings.
この考案の多管式貫流ボイラは、上部管寄せ１および下
部管寄せ２が多数の水管３によって連通されている。In the multi-tubular once-through boiler of this invention, an upper header 1 and a lower header 2 are communicated through a large number of water pipes 3.
下部管寄せ２の一部に試験片挿入口４が設けられている
。A test piece insertion port 4 is provided in a part of the lower header 2.
管寄せと同質材料から成る試験片５が挿入口４から下部
管寄せ２内へ挿入配置されている。A test piece 5 made of the same material as the header is inserted into the lower header 2 through the insertion port 4.
試験片５は管寄せと同質材料であるから、ボイラを長期
間運転後取り出し、これを観察することによって、罐内
の状態を推定することができる。Since the test piece 5 is made of the same material as the header, the condition inside the can can be estimated by taking the boiler out after a long period of operation and observing it.
この考案は多管式貫流ボイラについて記したが、他のボ
イラにおいても適用可能である。Although this idea has been described for a multi-tubular once-through boiler, it can also be applied to other boilers.
以上説明したようにこの考案は、構造簡単で効果的な罐
内腐食状態観察装置を提供することができるものである
。As explained above, this invention can provide an apparatus for observing corrosion inside a can that is simple in structure and effective.
