Title:
SYSTEMS AND METHODS FOR DE-ICING GAS TURBINE ENGINE INLET SCREEN AND DEHUMIDIFYING INLET AIR FILTERS
Document Type and Number:
Japanese Patent JP2015045330
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To prevent ice build-up on gas turbine engine inlet screens, without significant performance loss.SOLUTION: A manifold is coupled to an inlet screen. A first conduit is coupled to a compressor stage and to a first input of a mixing component. A second conduit is coupled to an exhaust and a second input of the mixing component. The second conduit extracts exhaust gases without increasing the pressure at the exhaust. A third conduit is coupled to an output of the mixing component and the manifold. If the current temperature at the inlet screen is less than a desired temperature at the inlet screen, a first flow rate of an air-exhaust mixture necessary to achieve the desired inlet screen temperature is calculated. The method also includes extracting an amount of exhaust gas from a turbine exhaust subsystem without increasing the pressure at the turbine exhaust subsystem, extracting an amount of air from the compressor stage, and mixing the amount of exhaust gas with the amount of air to generate an air-exhaust mixture that is conveyed to the inlet screen.
