ABSTRACT:
The air duct leading to a compressor for a gas turbine or the like often has water accumulating on walls and other structures. Water is removed from the compressor air inlet duct by drains connecting to the inside of the duct, including horizontal and vertical walls and the lower wall or floor of the duct. Drains are also provided on hollow structures such as struts, air inlet cone and inlet guide vanes upstream from the compressor. A suction pump or blower lowers pressure in the drain(s) to a pressure less than air pressure in the duct adjacent to the drain outlet for positively sucking water from the drain.
