Overview: Tenaska, an international power development company based in Omaha, Nebraska, placed orders for a Westinghouse 501F gas turbine generator and a Deltak fired HRSG for their Cleburne, Texas site. In response to Tenaska's need to maximize power production and maintain acceptable CO levels during summer peaks, Coen presented a two-step duct burner retrofit program. First, the system was computer modeled using Coen's in-house CFD capabilities. Then, the burner's flow baffles were modified to enhance Fuel/TEG mixing in this "low-oxygen/high-moisture" environment. This approach produced the desired results, while demonstrating that a more aggressive modification would be beneficial. The final answer to this challenging situation was to install Coen's prototype PowerPlus elements.
