Abstract: A system includes an exhaust diffuser system for a heat recovery steam generator (HRSG). The system includes an inlet portion, a diffuser portion axially extending from the inlet portion, and an outlet portion fluidly coupled to an axial distal end of the diffuser portion, wherein an outlet extent of the outlet portion is greater than an inlet extent of the inlet portion. The diffuser portion includes a plurality of wall portions, and the plurality of wall portions is incrementally angled relative to an axial extent extending from the inlet portion to the outlet portion. The system may further include a gas turbine engine coupled to the inlet portion and the HRSG.
