Abstract
A system, as well as associated methods, for increasing the efficiency of a gas turbine including an inlet assembly and a compressor may include a housing configured to channel airstream towards the inlet assembly, an air treatment module positioned at a proximal end the housing, and at least one air conditioning module mounted downstream of the air treatment module for adjusting the temperature of the airstream entering the compressor. The air treatment module may include a plurality of inlet air filters and at least one blower configured to pressurize the air entering the air treatment module.

An air treatment system for a gas turbine, the gas turbine including a compressor and an inlet assembly positioned to provide an input side portion of the gas turbine, the air treatment system comprising:
- a housing positioned to channel an airstream towards the inlet assembly;
- an air treatment module comprising:
- one or more inlet air filters to provide filtering of fluid flow to a first internal chamber, the first internal chamber including one or more outlets therefrom, and
- one or more blowers positioned in the first internal chamber to provide fluid flow to an interior of the housing through the one or more outlets of the first internal chamber, the one or more blowers positioned to pressurize air entering the air treatment module,
- one or more air conditioning modules mounted downstream of the air treatment module to decrease the temperature of the airstream entering the gas turbine compressor, such that air enters the one or more air conditioning modules at a first temperature and exits the one or more air conditioning modules at a second temperature lower than the first temperature;
- and
- a controller (a) in signal communication with a first temperature sensor and a second temperature sensor to receive the first temperature and the second temperature, respectively and with the one or more blowers to control operation of the one or more blowers, (b) configured to determine a pressure drop across the one or more blowers based on the pressure of air flowing into the one or more blowers and the pressure of air flowing out of the one or more blowers, and (c) to control the one or more air conditioning modules, and based on the first temperature and the second temperature, the controller configured to operate the one or more air conditioning modules to adjust the temperature of the airstream by a determined temperature.
