Abstract

The overall environmental regulations of the industry have been strengthened due to environmental pollution that occurred in modern society. Therefore, R&D of selective reduction catalyst (SCR) is needed to meet these environmental regulations. This paper carried out thermal analysis to develop the pneumatic damper valve (PDV), which is a key component of SCR system. For thermal analysis, verification of material properties was performed first. Verification was performed through the thermal properties test and the thermal tensile test of the specimen, and the results were reinforced with the material properties to enhance the reliability of the thermal analysis.The heat analysis was intended to identify thermal characteristics with PDV in total of three materials (SM400B, SS275, SB410) applied under the conditions of use of PDV, and to confirm the structural stability of the PDV.

현대사회에 이르며 발생한 환경오염으로 인해 산업 전반적인 환경규제가 강화되었다. 따라서 이러한 환경규제를 충족하기 위해 선택적 환원촉매장치(SCR)의 연구개발이 필요하다. 본 논문은 SCR 시스템의 핵심부품인 공압식 댐퍼 밸브(PDV)를 개발하기 위하여 열해석을 수행하였다. 열해석을 위해 우선적으로 재질의 물성치 검증을 실시하였다. 검증은 시편의 열물성시험과 열인장시험을 통해 하였으며 결과를 재질의 물성치에 보강하여 열해석의 신뢰성을 높이도록 하였다. 열해석은 유한 요소 프로그램(Ansys)를 사용하여 PDV가 갖는 사용 조건에 따라 적용된 총 3개 재질(SM400B, SS275, SB410)에서의 PDV가 보이는 열 특성을 확인하고자 하였으며, 이를 통해 PDV가 갖는 구조적 안정성을 확인하고자 하였다.
