Gas Turbine

Graver Technologies unique and patented Turbine Pre-Filter design extends the service life of primary filters.

Engineered Pre-filter Solutions for Gas Turbines

Gas turbines are combustion engines installed inpower plants to convert natural gas or liquid fuels into mechanical energy. Thisis used to generate electricity to supply end users along power lines. However,gas turbine air intake also brings in dirt and contaminants present in the air.To eliminate this issue, gas turbine filters are used. Graver Technologiesoffers a unique and patented turbine pre-filter that keeps the air clean andhelps extend the turbine’s operating life and energy efficiency. Gas turbine air intake filters are consumable itemsassociated with an installation. Extending their service life positively impactsoverall maintenance costs as small particles can lead to fouling, corrosion andplugging of cooling passages. Effectively controlling these particles iscritical to optimizing power output, maximizing component service life and fuelefficiency while minimizing the operating costs of gas turbine filtrationsystems.

Key Benefits of Graver’s Gas Turbine Filters

We offer TPF air intake prefilters that are fast, clean, and reliable pre-filters for gas turbine air intake systems, in addition to fine filters. These additional air filtration systems are designed to enhance system efficiency while minimizing maintenance downtime. Here are some key benefits of using our gas turbine filtration systems.

• Single piece design: Our gas turbine filtration systems are designed for quick change-out, allowing installation without the need to shut down the turbine’s industrial air intake system.

• Efficient and Easy Installation: Technicians do not have to remove the primary filters to install our pre-filters. They use a telescopic tool that allows for faster pre-filter change-out, reducing the time by up to 75% compared to competitive designs.

• Ultrasonic Seals: All seams are ultrasonic sealed, eliminating five of the six potential leak paths.

• Efficient Dirt Containment: Removal straps ensure that dust and dirt remain inside the pre-filter during change-out.

Why Choose Our Gas Turbine Filtration Systems?

Here are some reasons why you may want to partner with us for your gas turbine filtration system requirements.

• Long Service Life: While fine filters offer a high level of filtration. Our gas turbine filters serve as pre-filters that prevent the buildup of harmful particles, optimizing the lifespan of your turbine components.

• Improved Power Output: Filtration of contaminants present in the gas improves the overall efficiency of your gas turbine air intake system, ensuring maximum performance and minimal downtime.

• Cost-Effective Maintenance: The turbine gets clean air which reduces the frequency of maintenance and extends its operating life. These filters eliminate issues such as clogging, corrosion, fouling, and more are eliminated, making it cost effective in the long run.

• Higher Fuel Efficiency: This filter for gas turbine facilitates cleaner intake air, which results in low fuel consumption and improved efficiency as well as reduced operating costs.

How to Choose the Right Air Filtration Systems for Gas Turbines

Gas turbine filters are crucial to maintaining overall plant efficiency. They prevent particles and contaminants from sticking to the blade which could impact its functioning. Our pre-filters ease the job of fine filtration by eliminating the medium- to-big-sized particles. Here are some pointers on choosing the right pre-filter for your gas turbine application.

• Operating environment: If the operating environment is high on dust and contaminants then both fine filters and pre-filters are a must. Analyze all the parameters related to your operating environment and weigh them against the features of various gas turbine filters.

• Moisture and corrosion resistance: The filter must be made of materials resistant to moisture, corrosion, humidity, and more because the environment in which they operate would be mostly harsh and sometimes hazardous.

• Pulse recovery rate: Pulse jet cleaning filters are self-cleaning filters, which makes them suitable for high-dust environments. High pulse recovery may be needed, especially in high-dust environments as it is crucial for filters to quickly regain performance.

• Filtration efficiency: It is important to check how efficiently the filter captures particles. Check the filter ratings of models, such as MERV, HEPA, and EPA.

• Installation: Look for pre-filters that are easy to install and do not require the existing primary filters to be removed. Our filters fit this criterion.

Applications of Gas Turbine Filters

Here are some application areas of gas turbine filters

• Power generation: Gas turbine filters are used in base load power stations and hybrid systems that combine solar energy with a conventional source.

• Oil & gas: Gas turbines drive compressors and generators, wherein filtration systems prevent salt and hydrocarbon ingestion in corrosive environments.

• Industrial units: Gas turbines are used for CHP in many industrial plants such as cement, paper & pulp, and so on. Gas turbine filters prevent any particulate matter or contaminants on the floor from entering the turbines.

• Marine: Gas turbine filters are used in naval and commercial ships for protection from salinity and humid air.

• Military & defense: Gas turbines find application in tactical generators, and the filters are used for harsh on-field dirt, sand, contaminants, and so on.

Frequently Asked Questions

How often should gas turbine filters be replaced?

This depends on the environment and filter type; however, pre-filters are changed every 3–6 months, while final filters may bechanged once in a year or two. Monitoring pressure drop is key to determiningreplacement timing.

What factors affect the operating life of a gas turbine filter?

Here are some factors:

Ambient dustand pollution levels
Operatinghours and load
Pulse-cleaningfrequency, depending on the type
Humidity andmoisture
Filter mediaand design

How do I know when a filter needs to be changed?

Differential pressure across the filter is animportant aspect in this case. If it increases beyond the set threshold, thefilter may be clogged or need cleaning or replacement.

What is pressure drop and why does it matter?

Pressure drop is the resistance to airflow through afilter. A high-pressure drop reduces turbine efficiency and increases energycosts. Selecting low-resistance filters helps improve performance.
