gas turbine's operate at very high temperatures. so a thermal barrier coating is necessary to protect the gas turbine components. TBC's have low thermal conductivity. they also protect against oxidation and hot corrosion.

What is thermal coating?
Thermal coatings are highly advanced material systems applied to metallic surfaces, such as gas turbine or aero-engine parts, operating at elevated temperatures.
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.
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.
How do you increase a Thermal efficiency of brayton cycle?
by increasing the turbine inlet gas temperature
What is the efficiency of thermal power plant?
A modern combined cycle gas turbine/ steam turbine power plant can reach almost 60% efficiency.
What is the effect or reheater in the gas turbine?
1.Turbine output is increased for same compressor work. 2.As more heat is supplied,thermal efficiency decreases.
What are the effects of humidity on gas turbine performance?
an increase in relative humidity will increase the Gas turbine output. and thermal efficiency. when the ambient tempeature is high at that time also if RH is high it will have a slight positive impact on GT output & Efficiency.
What is the difference between combined cycle and cogeneration?
In Cogeneration Plant : The generated steam in boiler is used for both power generation & process heating, thereby reducing the condenstion losses compared to thermal power plant. In combined cycle first is gas turbine , rather than wasting the flue gas from gas turbine, we are sending it into boiler and again generating steam for running steam turbine. Both the ways we are increasing the thermal efficiency of the plant
What does thermal energy convert to?
Thermal energy is just heat. To convert it to mechanical energy you need some sort of heat engine, like an internal combustion engine or a gas turbine.
Gas turbine generator?
gas turbine generator
Is natural gas thermal or electric energy?
Neither. Natural Gas is Chemical Energy. In a thermal power station, the gas will be burned, heating the water. This is now heat energy. The superheated water (steam) will be blasted through a turbine or similar device. This then becomes kinetic energy or mechanical energy. The turbine then turns a generator/alternator. This converts the kinetic energy to electrical energy.
What is the defferences between a steam turbine gas turbine?
STEAM TURBINE is a machine for generating mechanical power in rotary motion from the energy of steam at temperature and pressure above that of an available sink. A turbine operated by highly pressurized steam directed against vanes on a rotor.HEAT ENGINE is a physical or theoretical device that converts thermal anergy to mechnical out put.....it converts heat energy into work.
