Benefits
Upgrades that enhance your gas turbine’s efficiency
This EGR solution eliminates the need for an inlet bleed heating system over a large ambient and part load range, improving overall heat rate.
Inlet heating with EGR can improve a unit’s heat rate up to ~2.5% at ISO conditions, ~40% relative load for simple cycle units, and ~1/3rd enhanced efficiency across cogeneration and combined cycle units.
Gas turbines utilizing EGR will achieve the same power output as inlet bleed heating, while achieving greater efficiency and maintaining emissions compliance.
How we get you there
- An air inlet heating system increases the temperature of the ambient air to the compressor inlet, decreasing air density, and improving overall compressor efficiency.
- Gas turbines operating at part load typically extract hot air from the compressor to achieve inlet air heating (often referred to as inlet bleed heating or IBH).
The air inlet heating system functions as follows:
- The inlet air is heated via a relatively small extraction of exhaust gases, which are recirculated via an inlet manifold system located in the air filter house transition piece.
- The air inlet heating system comprises of either a mechanical or backpressure type system to recirculate the exhaust gases, which will depend upon your specific site configuration.
- There is no impact on your gas turbine operation, reliability, protection or maintenance intervals when enhancing your air inlet heating with this EGR solution.
