Abstract
A gas turbine inlet heat exchange coil assembly includes a gas turbine inlet housing formed to include an inlet and an outlet and a flow path therebetween. A plurality of adjacent coils are located in proximity to the inlet, and moveable between a closed operative position where the coils are aligned substantially in a plane so as to maximize resistance to flow along the flow path, and an open inoperative position where said coils are individually rotated substantially 90° such that the coils lie in individual, parallel planes so as to minimize resistance to flow along the flow path.

A gas turbine inlet heat exchanger coil assembly comprising:
- a gas turbine inlet housing formed to include an inlet and an outlet and a flow path therebetween;
- a plurality of adjacent heat exchange coils located in proximity to said inlet and moveable between a closed operative position where said coils are aligned substantially in a plane so as to maximize resistance to flow along said flow path, and an open inoperative position where said heat exchange coils are individually rotated substantially 90° such that said heat exchange coils lie in individual, parallel planes so as to reduce resistance to flow along said flow path.
A gas turbine inlet compressor chiller coil assembly comprising:
- a gas turbine compressor inlet housing formed to include an inlet and an outlet and a flow path therebetween;
- a plurality of adjacent, substantially vertically-oriented chiller coils located in proximity to said inlet, and moveable between a closed operative position where said chiller coils are aligned substantially in a vertical plane so as to maximize resistance to flow along said flow path, and an open inoperative position where said chiller coils are individually rotated substantially 90° such that said heat exchange coils lie in individual, substantially parallel vertical planes so as to minimize resistance to flow along said flow path;
- and
- at least one actuator for moving said plurality of adjacent, substantially vertically-oriented chiller coils between said closed operative position and said open inoperative position.
A method of managing a power augmentation system located in an inlet filter house to a gas turbine comprising:
- (a) aligning individual heat exchange coils of a chiller unit so as to be substantially aligned within a substantially vertical plane when the power augmentation system is operating;
- and
- (b) rotating said individual heat exchange coils of the chiller unit so as to be oriented in plural substantially parallel planes and thus minimizing flow resistance, when the power augmentation is not operating.
