Power stations handling combustion of coal, oil, or biomass release large volumes of particulate-laden flue gas, which must be efficiently cleaned to meet emission standards and maintain public health standards. Advanced filtration protects turbines, heat exchangers, and other equipment from abrasive deposits and fouling, thus improving reliability, reducing maintenance, and supporting regulatory compliance. Filtration also enables recovery of valuable byproducts such as fly ash, which can be reused in cement or construction applications.

Large-scale operations often rely on Electrostatic Precipitators (ESPs) for fly ash removal due to their ability to handle vast gas flows and particles down to submicron sizes with efficiencies over 99 %. Baghouse fabric filters are increasingly adopted—either standalone or as ESP retrofits—thanks to their robust efficiency on fine particulates. Cyclone separators and mist eliminators pre-clean heavy particles before fabric or electrostatic systems. Liquid filtration systems such as coalescers and condensate polishers are essential for turbine lubrication, cooling water, and fuel processing.

Power plant filtration systems are engineered to withstand challenging flue gas conditions such as silica-rich ash, corrosive condensates, or sticky particulates. Inlet sections and hopper liners often incorporate wear-resistant materials. Moisture-resistant or coated media are used inside bag filters, and hot gas ESPs or dry filtration techniques prevent condensation. Such enhancements significantly prolong component life and maintain consistent performance.
