How inefficiencies of compressor and turbine affect back work ratio and efficiency of gas turbine?
Inefficiencies in the compressor of a gas turbine cycle increase the back-work ratio and decrease the thermal efficiency of the gas turbine cycle, since they increase the compressor work.
What is gas turbine compressor pulsation?
GT compressor pulsation ?
Which type of rotary compressor used in gas turbine?
Rotating axial compressor.
What is gas turbine pulsation?
GT compressor pulsation ?
How much energy air compressor alone consumes in the energy generated by a gas turbine?
Air compressor alone consumes about 50 to 60 % of energy generated by a gas turbine..
Disadvantages of centrifugal compressor in gas turbine?
This relationship is the reason advances in turbines and axial compressors often find their way cutaway showing an axi-centrifugal compressor gas turbine.
What is the self-sustaining speed of gas turbine?
self sustaining speed is output of a turbine= input into compressor
What is a CIT sensor?
Compressor Inlet Temperature sensorfor a Gas turbine engine.
What are the types of stator?
the types of statore are compressor, gas turbine, turboprop, and jet engine
What is intermediate pressure turbine?
Some varieties of gas turbine engines (e.g. RR Trent and RB211) have 3 concentric rotating shafts. Each shaft connects a compressor with a turbine. The low pressure compressor, or fan, is driven by the low pressure turbine. The high pressure compressor is driven by the high pressure turbine. Between the low and high pressure compressors there is an intermediate pressure compressor and, guess what... it's driven by the intermediate pressure turbine.
What is the technical reason for deterioration in performance of a gas turbine when the ambient temperature rises?
As the surrounding/ambient temperature increases, the temp of air entering the air compressor increases which means that the it's specific volume of air increases. Since the work of compressor = delta pressure x specific volume of air, then as the specific volume of air increases the work input of compressor increases and this is a problem because the total out put power of the turbine = work of the turbine - work of the compressor, so as the work of compressor increases, the total out put work of the gas turbine decreases. And that's why the efficiency of gas turbine is better in winter than in summer.
What property of the exhaust gas is being used to turn the turbine that runs the compressor?
At exhaust valve opening, pressurised gas reduces pressure by moving across the turbine blades and out of the exhaust pipe, the momentum of the moving gas is tapped by the turbine blades producing torque on the turbine shaft.
