CFD Analysis with Scale Model Verification - A Proven Cost-Effective Approach

Contributing Authors - Dave Dewees (Becht) and Dr. Keith Kirkpatrick (McHale Performance)  Reducing HRSG & Stack Pressure Drop to Improve Profitability Many operating Simple and Combined Cycle HRSG (Heat Recovery Steam Generator) ducts and stack exhaust system designs can be optimized to reduce pressure drop, improve combustion turbine backpressure, improve performance and increase revenue.  CFD analysis with Scale Model Verification is a proven and cost-effective tool for quantifying recoverable performance loss and improving generation plant profitability. Combustion Turbine exhaust/HRSG/SCR ductwork, breeching and stack systems require careful attention during detailed engineering and design. While EPC Contracts typically include both performance guarantees and liquidated damage provisions which are highly dependent on Combustion Turbine backpressure, the design of this critical stack system is many times “farmed out” to 3 rd party stack, HRSG or other less qualified suppliers. This practice can result in an un-optimized design with higher than necessary pressure drop resulting in reduced...
