To help improve the VAST Cycle technology, the VASTeam took a close look at the compression systems. A large portion of the energy produced by power cycles is used to drive the compressor and a large portion of the diluent or air that is compressed is often not even required for the combustion process but needed to keep things cool. Using fluid mixing, VAST has developed a compression system that:
- Increases compressor cooling.
- Reduces compressor work.
- Increases pressure ratios for the same thermal limits.
- Smaller compressor footprint.
- Injects water in each stage.
- Uses less air.
