Gas turbine intake air filter selecting system

A gas turbine intake air filter selecting system for selecting a filter to be provided in a gas turbine air-intake system for collecting dust, comprising:

• means for sorting by catalogue, for extracting from a catalogue data memory unit at least flow capacity, initial pressure loss and collecting efficiency of filters, and executing a first sorting of filters based on extracted data and performance requirement of each gas turbine;
• means for sorting by life span with respect to said filters selected by said means for sorting by catalogue, for extracting from a filter use environmental data memory unit at least atmospheric dust density, gas turbine operating time and gas turbine compressor intake capacity, calculating a life span of a filter based on data extracted from said environmental data memory unit and said collecting efficiency extracted from said catalogue data memory unit, and executing a second sorting of filters based on an outcome of said calculation;
• and
• means for sorting by cost with respect to said filters selected by said means for sorting by life span, for extracting from an actual plant data memory unit information related to actual gas turbine operation and information related to actual filter replacement, calculating an actual cost and an estimated cost respectively in relation to use of said filters based on data extracted from said actual plant data memory unit, unit price of said filter extracted from said catalogue data memory unit and said life span of said filters, and executing a third sorting of filters based on comparison of said actual cost and said estimated cost.
