Why Gas Turbine Exhaust temperature is above 500 deg C?
The exhaust temperature of gas turbines is very high due to the large amount of energy input into the inlet air by the combustion of fuel in the combustion chamber.
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.
How does the temperature vary across the gas turbine is there a formula for getting the work done in the turbine?
Read up on thermodynamics and then read the link concerning the Brayton Cycle. The temperature peaks just before it reaches the exhaust.
Why the temperature and the pressure of gas are decreasing after flowing out from turbine?
The gas (working fluid) having flown through the turbine does some work on the turbine, converting its thermal energy into mechanical work produced by the turbine and coming out as an expanding gas with lower temperature and pressure.
WHAT Is the maximum temperature in gas turbine plant?
The exhaust gases are often up to 500 Degrees C (940 Degrees F) but this can vary wildy depending mainly on load.
Description of alarms of ge gas turbine frame 7?
like any industrial gas turbine, alarms are: EGT high high vibration high delta P on air inlet filters high exhaust gas temperature spread low lube oil pressure low hydrulic oil pressure low control oil pressure high bearing temperature
What is the difference between a pulse system and a constant pressure turbocharger?
Types of turbochargers Turbochargers are of two types and they are pulse and constant pressure type turbocharger. Pulse type turbocharger: In pulse type turbocharger, the exhaust gas directly enters the turbine side and drives the turbine with the exhaust gas energy. The connection from the exhaust side of an engine is directly connected to the turbine side of a turbo charger. The pipe connections from the exhaust gas towards the turbine side are generally small in length and exhaust grouping is provided to prevent the blowback of gases from one cylinder to another. Constant pressure type turbocharger: In constant pressure type turbocharger, the exhaust gases gets collected in a single exhaust gas reservoir, where the pressure is maintained constant so as to avoid any fluctuation in the exhaust gas energy pressure. The exhaust gas is introduced to the turbine side after maintaining the pressure inside the cylinder. Materials: Turbine and compressor blades: Steel or nickel alloy. Volute casing: cast iron Bearings: steel or gun metal.
What is meant by frame classification of gas turbine?
frame classification means mainly depended the with standing temperature of the gas turbine casing.
What is TGT in relation to gas turbine engines?
Turbine Gas Temperature. see this page for more info incolor.inetnebr.com/iceman/pilot38.htm
What is effect if inlet temperature is increased on gas turbine?
Increasing the inlet temperature of a gas turbine can improve its efficiency and power output. This is because higher temperatures lead to better energy conversion and expansion of the gas, resulting in more work output from the turbine. However, there is a limit to how much the temperature can be increased before it affects the materials and components of the turbine, potentially reducing its reliability and lifespan.
What is n2 aviation?
2nd stage temperature of a gas turbine engine.
What gas is used to turbo the cars?
Turbo chargers are driven by the exhaust gases exiting the engine - engine exhaust drives a turbine in the exhaust system which, in turn, turn the turbo compressor.
