STEAG performs computational flow modeling for a wide variety of applications, including SCRs, large particle ash screens and FGDs. This service takes into account a number of factors, including:

• Flue gas flow
• Temperature distribution
• Ammonia and flue gas mixing
• Fly ash distribution
• Minimizing pressure drop

Flow modeling is especially important when there are multiple types of NO_x control technology being used in a plant, to ensure that they all work together as cooperatively as possible.

STEAG has conducted extensive modeling to examine the impact of large particle ash on SCR installations. As a result, modifications and/or additions can be made to areas like the economizer hopper, which allow for continuous and reliable SCR system and LPA screen operation.

In addition to physical flow models, STEAG also performs computation fluid dynamic modeling. For more information about CFD modeling, click here.
