Very complicated to make work reliably and very expensive.
gas turbine are used for expansion of high pressure gas,which rotates the rotor coupled with generator and hence electricity is finally produced.Gas turbine operate on brayton cycle.
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.
gas turbine generator
A gas turbine is one type of power plant. It produces power by burning gas to turn the turbine.
Self-sustaining speed in a gas turbine refers to the operational condition where the turbine can generate enough thrust and power to maintain its own rotational speed without external assistance. At this point, the energy produced from the combustion process matches the energy losses due to friction and other factors, enabling the turbine to operate efficiently. Achieving self-sustaining speed is critical for the turbine to transition from startup to stable operation.
Gas Turbine Research Establishment was created in 1959.
The function of IGV in a gas turbine is to prevent surges and stall conditions.
The first gas turbine in the Gulf started working in the 1970s
Gas turbine power generators are used in two basic configurations. Simple Systems consisting of the gas turbine driving an electrical power generator. You fill them with gas carefully & turn them in.
Gas turbines are generally more efficient than steam turbines, especially in terms of power-to-weight ratio and startup time. They can achieve higher efficiency in combined cycle setups, where waste heat from the gas turbine is used to generate steam for a steam turbine. However, steam turbines can be more efficient in large-scale power plants that operate continuously. Ultimately, the choice between the two depends on specific application needs, fuel availability, and operational conditions.

Steam and gas turbine power cycles are both used for electricity generation but operate on different thermodynamic principles. The steam turbine cycle typically involves heating water to create steam, which then drives the turbine, while the gas turbine cycle uses combustion gases to turn the turbine directly. Steam cycles generally have a higher thermal efficiency due to the ability to utilize heat recovery, but they require more water and infrastructure. In contrast, gas turbines are more compact, start up quickly, and are often used in peaking power plants, though they typically have lower thermal efficiency compared to advanced steam cycles.
