Abstract

In this study, the internal flow field of SCR Denitrification Plant was simulated by using Computational Fluid Dynamics(CFD). In order to analyze the uniformity of flow field, an interpretation on the pre-existing facilities was performed, and some moot points were identified and compensated through this analysis. The compensatory methods include the installation of the Porous Plate below the bottom of the Baffle to create uniform flow and also, and the Guide Vane was also placed in the bend of pipe to guide the flow uniformly. Lastly, the Baffle was installed to deduct equalized space distribution of the air flow, initially flowed into the SCR Plant.

본 연구에서는 전산유체해석(CFD)을 통하여 SCR 탈질설비 내부의 유동장 흐름을 전산모사하였다. 또한 유동장의 균일도를 분석하기 위해 기존 설비에 대한 해석을 수행하였으며 이를 통해 문제점을 도출하고 개선하였다. 개선방안으로는 곡관에 guide vane을 설치하여 곡관상에 기류를 균일하게 안내해 주었으며, baffle을 설치하여 SCR설비로 초기 유입된 기류의 균일한 공간 분포를 도출하였다. 마지막으로 porous plate를 baffle 하단에 설치하여 균일류 형성의 최적화 모델을 도출하였다.
