Selective catalytic reduction (SCR) is one of the most efficient methods to reduce NOx emissions from coal-fired power plants. This paper deals with an optimal design tower type SCR-deNOx facility for a 1000 MW coal-fired power plant. Combined with computational fluid dynamics (CFD), the configuration of the baffles geometry was studied with spatial constraints. Flow field was regulated at the ammonia injection grid (AIG) with the dual aim of reducing difficulties in implementing the non-uniformed ammonia (NH3) injection strategy and achieving a more homogeneous distribution at the catalyst entrance. A flow model test (FMT) was carried out at a laboratory scale to verify the design results. The results of the flow model test are in good agreement with the computational fluid dynamics. It is indicated that small-sized baffles are recommended for installation at the upstream side of the facility as the optimal design and ability to regulate the flow field at the ammonia injection grid makes it an effective way to deal with spatial constraints. This paper provides a good reference for optimizing the tower type SCR-deNOx facilities with spatial constraints.

“…Computational fluid dynamics (CFD) is an effective alternative to predict and understand flow-dependent processes and mixing phenomenon taking place in different inline mixers. Many researchers have used CFD to model the fluid flow in different inline mixers such as static mixers (Lang et al, 1995;Avalosse and Crochet, 1997;Hobbs and Muzzio, 1998;Kumar et al, 2007), curved tubes (Jiang et al, 2004;Vanka et al, 2004;Kumar et al, 2006), chaotic configurations (Niu and Lee, 2003;Jiang et al, 2004), etc. Lang et al (1995) investigated the turbulent flow in a static mixer.…”
