Abstract
Systems and methods for integrating heat exchanger elements of HRSG systems with gas turbine exhaust diffusers are provided in the disclosed embodiments. The systems and methods may include integrating heat exchanger elements, such as steam pipes, with various components of an exhaust diffuser. For example, the heat exchanger elements may be integrated with inlet turning vanes, exhaust frame struts, exit guide vanes, associated support structures, and other components of the exhaust diffuser. In addition, the heat exchanger elements may be integrated with multiple components of a single exhaust diffuser. Moreover, the heat exchanger elements may be integrated with the components of the exhaust diffuser within an airfoil, which may encompass both the heat exchanger elements and the individual component of the exhaust diffuser. The use of airfoils may help ensure certain aerodynamic properties of the heated exhaust gas flowing across the exhaust diffuser components.
