Construction parameters are carefullydeveloped. Transportation routes of pre-fabricated modules are fully-mapped out.Manufacturing sites, from Braden’s extensiveinternational network of fabricators, areselected based on technical expertise,proximity to the installation and any “local content” regulations.

Braden...The GT OEMs’ First ChoiceFor the last 40 years, Braden Manufacturing has occupied a unique spot halfway between the gas turbine OEMs and power producers. No other company has spent more time listening, learning, and working with both groups.

As a result, Braden has established itself as the mostexperienced and trusted name in the design of auxiliary systems for GT power plants. Turbine manufacturersacknowledge that no other company is better equipped to handle the challenges of GT plants:

Site-Specific Design GoalsEvery project begins with careful listening...listening todetermine actual needs, so as not to over or under-design.

Overall design considerations (simple or combined cycle; turbine selection; site layout, etc.) are only the beginning. An analysis of plant site’s weather data determines the inlet air treatment designs. It also influences material selection for various fabrications (e.g. stainless vs. mild steel).

Diverter Experience from the Extreme World ofCombined CycleBraden has designed and manufactured diverter isolators since 1985. The bulk of our diverterexperience is in combined-cycle gas turbine power plants, whereextreme and sudden thermal changes necessitate thorough designforesight. We have also designeddiverters for desulfurization (FGD)applications with several unique and patented features for improvedflow distribution.


Design Features• Flexible Inconel® seal elements

• Toggle or pivot drive system operation

• Thermal stress-free blade design

• Internal casing insulation

• Delivery in one piece or split intosections as per transportation limits

• Hydraulic power units with HRSGprotection mode

Braden has developed new retrofit designsthat will drastically reduce external heattransfer, making the Plenum/Wing/Cowl/Expansion Joint area safer, more efficientand easier to operate and maintain. Theseretrofit designs can be applied to plenumsof all sizes.

Let Braden’s Retrofit Engineers show youhow these design improvements can help

your system. A typical retrofit unit can beinstalled in one to two weeks during ascheduled maintenance outage, with thediffuser and turbine shaft in place.

Braden offers the manpower, equipmentand experience to install on your site...or we can provide detailed erection drawingsand procedures for your own crew.
