EXCHANGERS - COMPRESSORBleed air is ducted to the primary heat exchanger, then to the compressor.The air is cooled in the main heat exchanger. It then goes through thereheater, the condenser and the water extractor in order to remove waterparticles from the air entering the turbine.TURBINEThe air expands in the turbine section, which results in a very low turbinedischarge air temperature. The turbine drives the compressor and thecooling air fan.
