A gas turbine weather hood is the best possible protection against the ingress of rain, snow, sleet and hail. AAF weather hoods are designed so the air enters the inlet system vertically upwards and in doing so makes it extremely difficult for large amounts of moisture to enter the inlet filtration system.
A gas turbine or large compressor air intake filtration system forms a vital part of any given plant. The volume of intake air, the surrounding environment, and the operating conditions all play a major role in the design and filter element selection process. See related products for further details.
Inlet heating systems for cold climates are designed to protect gas turbines from damage due to icing and to keep the machine running with minimum effect on performance. Icing can block inlet filtration equipment, increasing pressure drop, and potentially cause the gas turbine to shut down.
Gas turbine output is affected by the temperature of the air entering the compressor. Gas turbines are rated at a temperature of 15 °C (59 °F). If the temperature increases above this point there is a loss of power, but this can be restored with AAF’s cooling solutions.
A gas turbine silencer is found in the intake as well as the exhaust to meet the overall noise control requirements. Once the acceptable sound level has been established it is then a matter of determining the amount of attenuation needed to reduce the noise to the desired level.
AAF enclosures provide an acoustic barrier, fire protection, turbine cooling and weather protection for your gas turbine and/or generator. Each enclosure is designed and manufactured to suit the individual requirements of the gas turbine being enclosed.
A gas turbine ventilation system feeds into the gas turbine enclosure and is designed to remove the hot air generated when the turbine is operating with ambient air from outside. Incoming air can be cooled or heated depending on the seasonal conditions and filtered to remove air contamination.
In a gas turbine application, a damper is used to allow the hot exhaust gas to either be discharged through a bypass stack or redirected into a Heat Recovery Steam Generator (HRSG). Steam is generated for industrial processes or to drive a steam turbine to generate more electricity.
A gas turbine or large compressor air inlet filter housing is usually above ground level and is held in position with a heavy-duty support structure, which includes a walkway for servicing. Ductwork is also a vital part of the overall gas turbine package and is used as a transition between the key component parts.
The gas turbine exhaust diffuser duct is where the gas turbine exhaust transitions into the exhaust system. The hot exhaust gas from the gas turbine flows through the diffuser in a straight line until it reaches either the diverter damper or the exhaust stack.
The gas turbine exhaust stack is a critical component of the exhaust system. Due to our years of experience AAF’s exhaust stacks are engineered to deliver optimal performance, reliability, and durability. They meet all OEM standards and can be adapted to your performance goals.
Our customer operates an 8 MW Solar Tauras 60 gas turbine for generating power, heating and chilling in a paper mill in Germany. The operator was experiencing compressor fouling and high pressure loses. Learn how operational performance was transformed through improved filtration.
