ラブル會未然に防止するため、使用燃料油中のバナジウ
ム量を把握し、的確な対策をたてる必要がある。When the vanadium content increases in fuel oil, high-temperature corrosion occurs due to the formation of vanadium compounds with low melting points. In order to prevent these troubles from occurring, it is necessary to understand the amount of vanadium in the fuel oil used and take appropriate measures.

的ダｌ識と時間全要する欠点がある。Analysis of vanadium in fuel oil is carried out using spectrophotometry or atomic absorption spectrophotometry after ashing and dissolving the ash in total acid in UJP and A8TM, but although these methods have good measurement accuracy, they require limited equipment. The drawback is that it is complex and expensive, requiring considerable chemical knowledge and time.
