Outline of Final Research Achievements

In this study, the objective was to develop a method to evaluate the monitoring performance of dust monitors (performance for small amounts and low concentrations of flue gas) and to determine the performance for each major detection method (light scattering, light transmission, and friction electrostatics). Specifically, we improved the performance evaluation device of the dust monitor. We developed a method that can evaluate effects on linearity and sensitivity for "concentration," "flow velocity," "dust deposition," and "dust characteristics." Furthermore, by conducting dust monitor performance evaluation tests using the method, we evaluated the effects of "concentration," "flow velocity," and "dust properties" for each of the major detection methods and clarified the characteristics of each.

Academic Significance and Societal Importance of the Research Achievements

ダストモニタの品質保証の規格化を加速させ、ばい煙濃度を低濃度まで確実に計測するためのダストモニタの評価基準が明確になる。自主管理精度の向上に資するだけでなく、公害防止のための測定器として周知でき、市場の拡大が期待できる。また、ダストモニタの評価基準の策定と普及は、連続的かつ高度にばい煙排出の厳格な監視・抑制を可能にし、ひいては我が国の大気環境保全並びに国民の健康保護に寄与することになる。
