석탄화력 발전소 탈질설비 내 곡확산부의 공력 특성에 대한 수치해석적 연구

Abstract

Numerical simulation has been performed to investigate the effect of the geometrical configuration of the curved-diffusing parts on the performance characteristics at the inlet of the catalyst layer in the DeNOx facilities. Application has been made to the existing SCR process in the large-scaled coal-fired power plants. The steady three-dimensional viscous flow fields with the proper turbulence model fitted to the flow characteristics were solved for three types of the duct shape. The numerical results showed that the type of Youngheong power plant is effective to improve the flow uniformity in the expense of the slight increment of the pressure losses.
