COMPRESSORS, GAS TURBINES AND JET ENGINES

Gas turbines has flat efficiency at part loads

Gas turbine requires lot of cooling water

Gas turbine is capable of rapid start up and loading

Gas turbines have high standby losses and require lot of maintenance

Large gas turbines use radial inflow turbines

Gas turbines have their blades similar to steam turbine

Gas turbines use both air and liquid cooling

Gas turbine's blade will appear as impulse section at the hub and as a reaction section at tip

Small frontal area and high h.p.

Low weight and small frontal area

High h.p. and low weight

High speed and high h.p.

Open cycle

Closed/open depending on other considerations

Closed cycle

Closed cycle & Open cycle

For operating pneumatic drills

In gas turbine plants

In starting and supercharging of I.C. engines
