An effective Air filter system cannot be ignored for the successful operation of a gas turbine. The filtration system protects the gas turbine from harmful debris in the ambient air, which can lead to issues such as erosion, FOD, corrosion and fouling. These issues will lead to bad performance and a shorter operational life of the gas turbine. Modern filtering system consists of a plurality of filter stages. Each stage is based on the local operating environment and performance objectives for the gas turbine selected. Selection of these systems can be a challenging task. To improve the working efficiency of the gas turbine, Gas Turbine Prefilters are necessary.

Because of Gas turbines ingesting a large amount of ambient air during operation, the turbine inlet air quality is an important factor affecting the gas turbine performance and life. A filtration system is used to remove harmful contaminants present. So it can control the air quality. Selecting the filtration system can be a daunting task, because there are many factors to consider. The system should be based on the turbine operating concept and target selection, the presence of pollutants in the ambient air because of expected changes in temporary or seasonal changes in emission sources of pollutants in the future. This paper outlines the primary considerations for selecting and installing Gas Turbine Prefilters. First, the consequences that can occur due to improper inlet filtration are reviewed. Then the different characteristics are discussed.

After this the components of a filtration system and considerations for the operating environment are outlined and lastly. Procedure for quantitatively comparing Gas Turbine Prefilters provided.

Learning so much information about gas turbine, are you interested in Gas Turbine Prefilters? Do you know Gas Turbine Pre Filter types? There are many Gas Turbine Prefilter types in the filter fields. In general, a pulse or self-cleaning type filter should be used when the dust loading approaches 0.400 mg per cubic meter or higher or when operating in conditions in which dust or sand storms may appear. Pulse filters can and have been successfully used in very dusty environments, such as cement plants, steel mills, Middle East environments, or areas where dust or sand storms are prevalent, even with high humidity. The pulse controller can be programmed to pulse as the loading requires. For example, a common recommendation for an installation in a cement factory is to minimize caking on the filters by automatically pulsing the filters whenever the relative humidity is greater than 81 percent. There are also other Gas Turbine Prefilter types are not mentioned. If you want to know more, please click www.hefilter.com.
