Abstract
Heat recovery steam generators (HRSGs) including bypass conduits for reducing fatigue and/or stress experienced by components within the HRSGs are disclosed. The HRSG may include a steam generator module generating steam, and a first superheater module positioned downstream of the steam generator module. The first superheater module may receive the steam generated by the steam generator module. The HRSG may also include a second superheater module positioned downstream from the first superheater module, and a bypass conduit for receiving a portion of the steam generated by the steam generator module. The bypass conduit may include an inlet positioned downstream of the steam generator module, and an outlet positioned downstream of the first superheater module. Additionally, the HRSG may include a valve in fluid communication with the bypass conduit to provide steam to the outlet of the bypass conduit.
