Heat Recovery Steam Generators (HRSGs)

Designed and Delivered to Meet Your Needs.

Our utility-sized HRSGs are designed to recover and recycle heat energy from gas turbine exhaust. A HRSG produces steam that can be used in a process (co-generation) or used to drive a steam turbine (combined cycle). We offer multiple construction options to meet unique site-specific applications, and we design products to meet codes and standards such as: ASME, TRD, IBR and PED/CE. Whether you need HRSG optimization, service, improved efficiency, inspections, or parts and service, Vogt can handle your requests.

V-Series HRSG Designs.

V-Lite

Self uprighting module.
Main columns pre-assembled with side casing (where shipping clearances allow).
Nested downcomers shipped with casing and main steel.
Eliminates removing shipping frame and attaching a lifting frame, no special lifting fixtures required.
Reduction in seal welding at site, lifting lugs, and lift plan included.
Reduces pipe field welds for large diameter pipe.

V-Flex

Reduces field labor hours, no field-installed insulation needed between “cold” boxes.
Shipping and uprighting steel shop-installed on each box.
Collection headers in attic and basement where feasible.
Top, side, and bottom casing attached to module box, compression fit liner panels in the “cold” boxes.
No lifting frames required. Shipping steel does not have to be removed from “cold” boxes.
Minimizes penetrations and reduces field pipe welds.

V-Max

Main support columns, top, side, and bottom casing attached to module box.
No field-installed insulation needed between “cold” boxes.
Nested downcomers shipped with module box.
No lifting frames required, only two moment connections per column line.
Reduces field labor hours.
Reduces pipe field welds for large diameter pipe.

V-One

Incorporates the ultimate in prefabrication.
Stack delivered in full cans to the site.
Dramatically reduces erection schedule and field labor hours.
Field hours and schedule reduction.

Innovation is Our First Order of Business.

A HRSG converts gas turbine exhaust into power for the steam turbine in a combined cycle power plant. 135 years after producing the very first HRSG, Vogt is the one-stop source for Excellence-In-Heat-Recovery^® to operators of more than 600 HRSGs in over 40 countries. We deliver the most constructible and cost-effective HRSG unit for each site-specific application. Our modular designs and pre-fabrication options vary depending on the size of the HRSG, desired transport alternatives to the job site, and labor cost and availability.

Vogt’s extensive global installed base is extremely diverse, including some of the largest units operating today, as well as some of the most complex. These custom-built designs work behind combustion turbines from 25 MW up to 550 MW or more, for use in power generation, co-generation, IGCC, enhanced oil recovery (EOR), combined heat and power (CHP).

Vogt HRSGs feature a horizontal or vertical gas path, may be ordered with one, two, or three pressure levels and with or without a reheat system. Our extensive capabilities include auxiliary-fired units, supply of Selective Catalytic Reduction Systems (SCRs), CO systems, and additional design features such as stack dampers, silencers, shrouds, and exhaust bypass systems.

No matter the configuration, Vogt builds HRSGs that last, focusing on long-term operation at every step of design and construction, taking into account factors such as fast starts, rapid response, cycling, Flow Accelerated Corrosion (FAC), startup emissions, and flue gas distribution.
