Gas Turbine Air Filter System Optimization

摘要

Proper air filtration is critical to the overall performance and reliability of gas turbines. Fuel costs approach 80% of the life cycle cost of electricity. Small gains in efficiency can mean huge savings. With fuel costs of around $16.00/mmBTU and higher in certain global regions, operational savings can be achieved through improved compressor performance using High Efficiency (HEPA) air filters. Operators can see greatly reduced maintenance costs as a result of a much cleaner engine, quantified by less frequent inspections, fewer shutdowns, and higher availability. HEPA filtration can maintain optimum GT efficiency throughout the life of the filter. This paper will explore the decision criteria required in selecting an optimum air filtration solution, with a goal of maximizing gas turbine availability and lowering operating costs. Through case studies and analysis, the review will explore the impacts on essential filter parameters and their impact on gas turbine operations and maintenance.
