The present application provides a steam discharge pipe blowback protection system for use with a steam discharge pipe and a flow of steam therethrough. The steam discharge pipe blowback protection system may include a vent stack pipe and a drip pan with an exit end of the steam discharge pipe extending through the drip pan and into the vent stack pipe. The drip pan includes a slide plate positioned around the steam discharge pipe such that a blowback in the flow of steam causes the slide plate to seal the drip pan.

Steam discharge pipe blowback protection system

A system for aggregating a working fluid includes a fluid delivery line defining a fluid connection to at least one downstream process component; a plurality of collection lines each fluidically connected to a plurality of header lines by a respective set of header links; and a connecting junction fluidically connecting each of the plurality of collection lines to the fluid delivery line, the connecting junction including: at least one tee member oriented substantially perpendicularly with respect to the fluid delivery line, the at least one tee member connected to the fluid delivery line, and a plurality of branch fluid lines each fluidically coupling a respective one of the plurality of collection lines to the at least one tee member.

System to aggregate working fluid for heat recovery steam generators

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.

Bypass conduits for reducing thermal fatigue and stress in heat recovery steam generators of combined cycle power plant systems

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.
