How Gas Turbines Work? (Detailed Video)

Показать описание
A gas turbine, also called a combustion turbine, is a type of continuous combustion, internal combustion engine. The main elements common to all gas turbine engines are:

1. An upstream rotating gas turbine compressor;
2. A combustor;
3. A downstream turbine on the same shaft as the compressor.

A fourth component is often used to increase efficiency (on turboprops and turbofans), to convert power into mechanical or electric form (on turboshafts and electric generators), or to achieve greater thrust-to-weight ratio (on afterburning engines).

The working principle of a gas turbine is a Brayton cycle with air as the working fluid. Atmospheric air flows through the compressor that brings it to higher pressure. Energy is then added by spraying fuel into the air and igniting it so the combustion generates a high-temperature flow. This high-temperature high-pressure gas enters a turbine, where it expands down to the exhaust pressure, producing a shaft work output in the process. The turbine shaft work is used to drive the compressor; the energy that is not used for compressing the working fluid comes out in the exhaust gases that can be used to do external work, such as directly producing thrust in a turbojet engine, or rotating a second, independent turbine (known as a power turbine) which can be connected to a fan, propeller, or electrical generator.

Weve been crating these parts up for years. I like watching how it all works all put together.

Love the video, glad there is no irritating music in background 😆

The compressed air enters the compressor discharge case, is warmed and expanded into energy in the combustion cans/chambers which, through transitions, directs the expanded energy into the turbine section. Here the energy is expended across the turbine sections, creating the torque necessary to drive the generator and create power.

A good explanation, I liked the information on combined cycle

All gas turbines of different types depend in their work on drawing air from the outside and then increasing its pressure and speed with condensers to tens of atmospheric pressure according to the number of feather discs so that the friction between the compressed air particles increases with each other inside the condensers, which raises the temperature of the compressed air to many times the boiling point of water to accelerate the combustion of the fuel spray coming out of the syringes in the combustion chamber, which increases the efficiency and concentration of the directed kinetic energy resulting from the combustion, so that the combustion product acts as a feedback by moving the exhaust blade discs connected to the same axis of the compressor discs, and in the case of imbalance of the concentrated air pressure inside the condensers, the energy produced in the combustion chamber they will be dispersed to all directions and may cause an explosion inside the gas turbine. This is why the margin of error during manufacture of the turbine disc blades does not exceed several microns to maintain the stability of the flow of compressed air inside the condenser.

Thank you brother for your good explanation 😊😊😊🙂🙂🙂

Do we use just air to rotate the turbine? is there a need to burn natural gas?
Which gases we can use as a natural gas?

There are two types of blade in fan(turbine also) one is suck the air and other one who blow the air???



In turbine which type of blade is

Very concise video, thank you. I imagine for a ship engine, the mechanical energy created is used to rotate the propellers?

Can you have multiple steam turbines all in series as the steam passes from turbine to turbine? This also makes me wonder why hydroelectric plants don’t have hundreds of turbines catching water one after another?

Two thoughts: '101' is one of if not the only slang term that's been in continuous use since 1929 . . . . . two: is it RPM or RPM's?
