A Healthy Inlet System Equals a Healthy Turbine

The gas turbine air inlet system ensures clean air reaches the turbine during combustion. Air is drawn into the filter house, where large dust particles and moisture droplets are removed. Filter elements inside the chamber further clean the air before it exits through the transition section and moves into the inlet ducting system. This process is essential for maintaining the turbine's efficiency and performance.

Gas turbine filtration systems can be either static or self-cleaning. Static systems use pre-filters and final filters that are replaced when dirty. In contrast, self-cleaning systems automatically clean the filters once dust accumulation reaches a certain level, determined by the pressure drop across the filters. Both systems ensure clean air is delivered to the turbine, but self-cleaning systems add the advantage of reduced manual maintenance.

Cooling the air before it enters the turbine can significantly boost power output and efficiency. Cooler, denser air allows for more fuel to be added during combustion. Integrated cooling systems, such as media-type evaporative coolers, can be installed within the filter house to optimize turbine performance by providing denser air to the turbine compressor.

An inlet air filter house works alongside inlet ductwork to deliver clean air to the turbine compressor while minimizing noise and pressure drop. This ductwork ensures that the air remains uncontaminated and efficiently flows to the turbine, supporting seamless operation. IPS specializes in improving the performance of key GT inlet system components, including the filter house, inlet duct, inlet silencer, and inlet plenum.
