Systems and methods for reducing thermal stress in pressure vessels

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.
