Computational Fluid Dynamics

Use of Computational Fluid Dynamics (CFD) Modeling with Boilers & Boiler Auxiliaries

Computational Fluid Dynamics (CFD) is a sophisticated, computer-based simulation analysis of systems involving fluid flow, heat transfer, and related phenomena such as chemical reactions. It is a powerful technique and spans a wide range of power generating industry applications.

Riley Power Inc. (RPI) offers CFD modeling services to power plant operators for any OEM’s equipment. With nearly 30 years of experience using the FLUENT software, our engineers are proficient in the application of CFD modeling for all types of boiler applications. Because we are a boiler OEM with knowledge of all types of steam generating and combustion systems, we can identify, analyze, and provide complete solutions to a wide range of real-world problems.

Examples of using CFD modeling for power plant applications include:

• Coal burning and combustion analysis to determine the effects of fuel switching, for example, burning Petroleum Coke or PRB coal in an existing boiler.
• Analysis of the effects of installing new low NOx burners on combustion and thermal performance in an existing boiler prior to burner installation.
• Determining the effect of increased draft loss from the additional ductwork associated with installing post-combustion NOx and SO2 emissions control equipment (SCRs and scrubbers).
• Analysis of the flow of the air/pulverized coal mixture in a coal pipe network to improve coal flow distribution, improve pulverizer performance, and reduce coal pipe and burner head erosion.
• Analysis of gas flows in a furnace for designing or optimizing boundary or overfire air (OFA) systems to ensure proper O2 concentrations at critical locations in the furnace.
