A Study on the Development of ppb Level Dissolved Silica Measuring System
ppb Level 실리카 측정시스템 개발에 관한 연구
Abstract
Dissolved silica is make some critical trouble at steam turbine. And, we must measure it to ppb level. We were looking for the best measuring method of the silica. Via this study, we could found it in the N-IR spectroscopy technology. This dissertation have been discuss about system structure, system fundamentals and performance test. At the test, we were study in the spectral interference of
