Have an intake system that has heavy corrosion and needs a replacement?
Have an intake system that is underperforming aerodynamically or acoustically?
Have icing issues that hurt your plant availability?
Need help inspecting your existing intake to review options to replace or upgrade?
Combustion turbine intakes require clean air with optimized aerodynamics, and SVI-BREMCO can provide turnkey support.
SVI BREMCO can help by providing inspection, analysis, design, supply, and installation to meet all of your project goals.
SVI BREMCO is an industrial equipment supplier that provides gas turbine air intake systems
A traditional gas turbine system may use weatherhoods on the face, which were used to keep the elements out. However, these traditional weatherhoods have very poor aerodynamic performance when compared to an intake louver. SVI BREMCO has experience with retrofitting the weatherhoods with louvers, which provide the following benefits:
- Marine-grade materials for corrosion resistance in any environment
- Improved moisture removal with louver design
- Improved aerodynamics and better uniformity to ensure optimal intake performance
- Option to include anti-icing heated louver technology to ensure unit availability during inclement weather
SVI BREMCO's Turnkey Solutions
SVI BREMCO can service all the parts of your Combined Cycle plant including:
Dealing with Corrosion in Gas Turbine Air Intakes
Corrosion in a gas turbine air intake is not uncommon over time, and inspections of the intake system are important to ensure the gas path is kept clean. SVI BREMCO can provide support for:
- Intake inspections
- Intake cleaning and coating upgrades for corrosion resistance
- Intake filter changeouts (including high-efficiency filters)
- Intake silencer retrofits and upgrades
- Intake redesign and turkey retrofits
Original intake ducting can be painted carbon steel. Over time, the paint system can degrade, exposing the carbon steel casing, which, when not protected, can corrode. SVI BREMCO can provide support to recondition intake systems that need new corrosion control systems. Additionally, we have experience upgrading the intake ductwork with materials like stainless steel that would improve the durability and corrosion resistance of the system.
Gas Turbine Silencer Upgrades and Redesigns
These turbine intake upgrades can include the silencer system as well. Depending on the original equipment materials of construction, the silencers may become corroded. In applications where corrosion is of top concern, SVI BREMCO can provide an upgraded silencer design, including silencer panels fabricated with 300 series stainless steel. This eliminates the potential for corrosion and the risk of foreign material ending up downstream in gas turbines.
During the process of analyzing a turbine intake for improvement upgrades, silencer redesign options may be worth considering. A silencer in an intake system is typically required to at least meet the near-field site criteria. A good silencer design will minimize back pressure while balancing acoustical and aerodynamic goals. SVI BREMCO can review optional silencer designs to minimize pressure drop while guaranteeing acoustical performance to meet project goals.
Inlet Air Filtration Systems for Gas Turbines
A gas turbine power generation system relies heavily on its inlet air filtration system. These systems within the filter house employ a series of filter stages designed to progressively remove contaminants from the air. The initial stages of the filter systems use larger air filters to trap coarser particles, protecting subsequent finer filtration stages from quick fouling. The additional stages involve more intricate air filters that capture smaller and smaller particulates to prevent damage to the turbine’s delicate internal mechanisms. Integrating comprehensive filtration systems within the filter house is important to maintain the integrity and performance of gas turbines.
Challenges with your gas turbine system can vary considerably depending on various factors, like the design and operation of the turbine, as well as environmental conditions, like ambient air temperature and quality. We evaluate these factors to ensure we improve your gas turbine performance and high filtration efficiency.
Turbine Inlet Air Cooling and Anti-Icing
Additional ancillary equipment for intake systems includes turbine inlet air cooling (TIAC) and anti-icing (intake heating). SVI BREMCO can help design, supply, and install equipment options to accomplish a site’s intake cooling or heating goals. Please contact us to discuss your specific intake performance requirements for cooling options.
Colder intake air helps improve turbine power output, but in certain environments, when the colder air is from inclement weather, it can negatively impact intake performance. Anti-icing is a concern for gas turbine power plants that operate in colder geographies. When weather conditions are icy and snowy, it can accumulate in the filter section of the turbine intake, which reduces airflow, potentially shutting the unit down or forcing it into an outage. To prevent the ice build-up at the front or upstream section of the filter house, SVI BREMCO can provide heated louvers. This ani-icing solution takes the benefits of the louvers mentioned above and integrates a heat trace technology that heats the air stream coming through the louver, preventing snow build-up and ice from forming on intake components.
The heated louver system provides improved aerodynamics, better moisture removal, and anti-icing. Additionally, the accessibility for the heated louver turbine air intake system retrofit is all at the front of the filter house face, making it a very unobtrusive project.
Download our Stack Inspection Checklist from SVI BREMCO'S Experts
We’ve developed a stack inspection checklist to help you identify problems before they lead to plant downtime. There are several good reasons to inspect your stack:
- Do you want to prevent downtime?
- Have you noticed significant degradation of any structural component?
- Has your stack experienced an unusual event such as an explosion, earthquake, fire or overheating?
Knowing what you should inspect annually and every three years saves you time, money, and stress.
