What is cranking in a gas turbine?
Cranking in a gas turbine refers to the process of initiating the engine's startup sequence by rotating the turbine's shafts using an external power source, typically an electric motor or a dedicated starting system. This action allows the gas turbine to reach the required speed for fuel ignition and combustion. Cranking is essential for overcoming inertia and ensuring smooth acceleration to operational speeds before the turbine takes over and self-sustains its operation.
What is turbine barring system?
A turbine barring system is a mechanism used to rotate a gas or steam turbine slowly when it is not in operation. This slow rotation helps to evenly distribute temperature and prevent thermal stresses, thereby extending the life of the turbine components. The system typically engages the turbine shaft through a barring drive, allowing for maintenance and inspections while ensuring that the turbine remains in optimal condition. It is crucial for preparing turbines for startup and for maintaining their health during extended outages.
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 use the word turbine in a sentence?
My dadd uses turbine to heat the gas of hiss engine after he stopped at the gas stop and didn't find any gas left. ( This may be a weird looking sentence for turbine,but at least I got an A on it. )
Where are ratchet mechanisms used?
Ratchet mechanisms used in Gas power plant for Gas Turbine. (like Barring gear in steam turbine).
What is the definition of combined cycle turbine technology?
Using waste energy in a gas fired electricity generation plant to run a steam turbine
What is the difference between a Gas turbine engine ignition system and a piston engine ignition system?
Main difference is that in a gas turbine, combustion is continuous. In a piston engine, combustion is pulsed.
Gas turbine generator?
gas turbine generator
Definition of open cycle gas turbine?
An open cycle gas turbine (OCGT) is a type of gas turbine that converts fuel energy into mechanical energy through a continuous process. In this system, air is drawn in, compressed, mixed with fuel, and combusted, generating high-temperature exhaust gases that drive a turbine. The exhaust gases are then released into the atmosphere, making the cycle "open." OCGTs are often used for peaking power plants due to their quick startup times and ability to meet fluctuating energy demands.
What is the cooling system of gas turbine blade?
In order to enhance creep life of gas turbine blade, it is required to keep blade at lower temperature, hence internal cooling of blade is done.
Why is the gas turbine called as the power plant?
A gas turbine is one type of power plant. It produces power by burning gas to turn the turbine.
When was Gas Turbine Research Establishment created?
Gas Turbine Research Establishment was created in 1959.

What is the function of IGV in gas turbine?
The function of IGV in a gas turbine is to prevent surges and stall conditions.
When first gas turbine works in gulf?
The first gas turbine in the Gulf started working in the 1970s
What is a gas turbine power generator?
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.
