Abstract: Hinged baffle assemblies for heat recovery steam generators (HRSGs) are disclosed. The baffle assemblies may include a baffle plate for directing exhaust fluid through a casing of the HRSG. The baffle plate may include first and second ends, a first surface exposed to the exhaust fluid flowing through the casing, and a second surface opposite the first surface. The baffle assemblies may also include a hinge component coupled to the first end of the baffle plate and positioned within/fixed relative to the casing. Additionally, the baffle assemblies may include a first diverter plate positioned adjacent to the second end of the baffle plate. The first diverter plate may directly contact the first surface of the baffle plate and may aid in directing the exhaust fluid through the casing of the HRSG.

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.

Abstract: A system includes a heat recovery steam generator (HRSG) configured to generate steam from a supply of feed water using exhaust gases. The HRSG includes a heater configured to receive a supply of steam and further heat the steam. The heater includes a first manifold and a first set of branch connections circumferentially spaced about a first circumferential axis of the first manifold. Each of the branch connections routes a fluid jet of steam into a lumen of the first manifold.

Abstract: Heat recovery steam generators (HRSGs) including components and systems for reducing thermal stress experienced by manifolds within the HRSGs are disclosed. The HRSG may include a manifold receiving a working fluid of the HRSG, a plurality of piping links in fluid communication with the manifold, and an enclosure surrounding the manifold and the plurality of piping links. The HRSG may also include at least one thermal element positioned within the enclosure. The thermal element(s) may surround the manifold. Additionally, or alternatively, the HRSG may include a supplemental heating system in fluid communication with an interior of the enclosure. The supplemental heating system may include a heater for heating fluid (e.g., air), and an inlet conduit in fluid communication with and positioned downstream of the heater. The inlet conduit may be formed through the enclosure to provide the heated fluid to the interior of the enclosure.
