inlet part of the compressor when the valve is in the open
2. It seals the running clearances to minimize air
(load) position. Fresh water is injected into the airstream
as it passes through the inlet port of the compressor
Most of the injected water is entrained into the
casing. The injected fresh water serves two purposes:
airstream as it moves through the compressor.
1. It reduces the air discharge temperature caused
The compression cycle starts as the rotors unmesh
at the inlet port. As rotation continues, air is drawn into
