Engineering Studies & Modeling.

We understand the HRSG failure mechanisms, from operational cycling, duct firing, to under deposit corrosion. Our services team is committed to serving the needs of the HRSG users in maintaining and operating their equipment in the ever-changing market.

CFD models are used to evaluate gas temperature distributions downstream of burners and identify locations for temperature peaks. Our thermal software can evaluate impacts from a GT upgrade on all the pressure parts and advise if any changes are required.

Studies & Models.

Vogt provides expertise on any and all applications where experience with the design and equipment is invaluable.

GT Upgrade:

Whether it is a new combustor, rotor or frame upgrade, Vogt Power has the ability to model the whole system and highlight the problem areas that emerge with a change in the power train and the ability to make the recommendations that would allow the system to function as a whole without issues.

Heat Balance and Heating Service:

Performance degradation, removal or addition of heating surface, changes in geometry, and/or complete retrofits of major surface are all modifications that Vogt can analyze in detail and provide predicted performance.

Thermodynamic and hydrodynamic modeling of heating surface to realize performance gains in steam production.

Validating an HR drum’s temperature ramp rate for longevity and /or verifying that an engineered pipe support can bear the load of a new valve are just two examples of services our mechanical and pipe stress department can field.

Any sort of discipline engineering required

Analyze gas turbine, steam turbine and HRSG for performance, Major components and BOP equipment.

Engineering study to quantify performance changes in the balance of plant equipment or heat recovery steam generator.

Engineering study to assess the feasibility of a retrofit

Offering the ability to completely analyze a boiler from top to bottom to facilitate a transition from base load operation to cyclic and fast start operation, focusing on end of useful life analysis to get the most out of the HRSG.

On-site walkdown and assessment of equipment using specialized inspection equipment such as ultrasonic sensors.

Determine if flow is evenly distributed to access heat transfer surfaces.

Be it inlet duct design, flow distribution grids, turning vanes, burner ducts, ammonia flow, or catalyst flow distribution, the CFD team has the experience and expertise to address any problem.

Engineering study to predict, modify, or quantify the impact from the startup and shutdown of the major equipment in and around a heat recovery steam generator.

Comprised of the examination of the gas turbine upgrade.

Whether it’s installing a new catalyst into an existing spool duct or coming up with a unique solution that allows installation of catalyst into a unit not designed to carry it, Vogt Aftermarket Services can engineer a solution to meet the air permit and the application. Examples include:

Low Temperature — precious metal (330°F – 520°F)

Intermediate Temperature — Vanadia/Titania (500°F – 840°F)

High Temperature — Zeolite (650°F – 1100°F)
