In case of a long route EGR arrangement in which the EGR and air are mixed before the compressor, water condensation will cause significant damage to the impeller and the
compressor efficiency will decrease, [19].
CMCs are a key technology advantage for GEs advanced military engines under development, which are setting propulsion records for
compressor efficiency and operating temperatures.
Furthermore, it is expected in actual use that the pressure raise of the ejector will lower the compression ratio of compressor and improve the
compressor efficiency.
Compressor efficiency of calculating by air volume and electricity showed that the compressor was only half as efficient as new one spec for aging as shown in Figure6.
Diesters: Diesters cause sludge, which can become costly by reducing
compressor efficiency.
While the cases with slower ramp rates avoid the regions of lower
compressor efficiency, as well as the high off-optimum power turbine speed at high load, the higher average engine efficiency for the faster ramp rates is better than for the slower ramp rates (Figure 4).
By improving
compressor efficiency and recovering heat energy for heating administration rooms, the green salad and herb producer has saved more than 18,000 [euro] per year since it introduced the Boge compressed air and nitrogen formula.
The
compressor efficiency gain was achieved by advancing the design of the compressor impeller, volute, variable diffuser vanes, inlet guide vanes and controls.
Eventually, the decrease in
compressor efficiency (see below) over takes the increased heat exchanger efficiencies.
This has a significant impact in reducing high
compressor efficiency and stall margins, in these very low aspect ratio blade passages.
Choosing non-genuine or third party spares can have a negative impact on
compressor efficiency and energy consumption.
The decrease in screw
compressor efficiency at part load is less severe in lower compression ratio applications.
