A combined-cycle power plant uses both a gas and a steam turbine together to produce up to 50 percent more electricity from the same fuel than a traditional simple-cycle plant. The waste heat from the gas turbine is routed to the nearby steam turbine, which generates extra power.
Proper air filtration is critical to the overall performance and reliability of gas turbines. Fuel costs approach 80 percent of the life cycle cost of electricity. Small gains in efficiency can mean huge savings. The decision criteria required in selecting an optimum air filtration solution, with the goal of maximizing gas turbine availability and lowering operating costs.
Air inlet filtration systems are essential for the operation of gas turbines and other turbomachinery. Gas turbines ingest a large amount of ambient air during operation. Because of this, the quality of the air entering the turbine is a significant factor in the performance and life of the gas turbine.
The most notable symptom of efficiency degradation for Gas Turbines or compressors is fouling. The correct choice of air filtration will save hundreds of thousands of euros – every operating year, every unit.
