=============================
Two of the most common applications of Gas Turbines in modern industries are Turbo Generators and Turbo Compressors.
We try to approach a Gas Turbo Generator (GTG) to better feel the subject.
In a Gas Turbine Power Plant, there’s a Generator which is an electrical machine. But to generate electricity this generator needs a Prime Mover which for my example is a Gas Turbine.
Gas Turbine transforms the chemical energy in the fuel (i.e. natural gas or the similar fuel) into mechanical energy.
The mechanical energy generated by the Turbine exit shaft is then transferred through a gearbox to the Generator’s shaft. Now my generator can create electrical energy.
This primitive form of electrical energy normally has a low or medium level of voltage and to better manage the power loss in transmission lines, this voltage should be increased by step-up transformers.
Such transformers give an adequate level of voltage to the electrical energy to be transmitted through the transmission lines and delivered to the grid.
After this brief overview of a sample Gas Turbine application, I’m going to dig down into the Gas Turbine mechanism in more detail.
First, imagine a rocket in which some fuel is going to burn and create a high-pressure exhaust gas. Based on energy conservation law, the chemical energy of the fuel is transformed into mechanical energy in the high-pressure exhaust gas.
When a rocket is fired, the thrust of this exhaust gas moves the rocket forward. This amount of rocket science is enough for me and now suppose I fix the rocket body with a robust mechanical structure to prevent its movement.
What will happen? The high-pressure exhaust gas should be released and it will have no way but backward!
Now keep this structure in mind and imagine I put a set of turbine blades in the path of this high-pressure back-fired exhaust.
You see that the release of mechanical energy which is mostly in a “linear” backward direction will mostly transform into kind of “rotational” movement of turbine shaft and so far I’d say it’s a big success, i.e. transforming the chemical energy of fuel gas into rotational mechanical energy of turbine shaft.
Now I have a “Prime Mover” for my generator in the above power plant example. Also, this prime mover concept can be used in different applications like turbo compressors or the likes.
Now that I got the basics of Gas Turbines, let’s focus on a modern Gas Turbine and its components.
Most likely you know about “Fire Triangle” or “Combustion Triangle” which illustrates the necessary ingredients of fire or combustion, i.e. “Fuel”, “Air”, and “Heat”.
To transform the chemical energy of the fuel gas into mechanical energy, the fuel should be burnt in the “Combustion Chamber” of a gas turbine, so I need air and heat added to the fuel.
Air is let into the gas turbine through “Air Intake” and mixed with a proper amount of natural gas. The Air/Gas ratio is determined based on the specific heating value of the gas and quality of the air, amount of moisture, altitude from sea level and so on.
Now an ignition system steps in and makes the initial sparks, so hereby heat is provided. When the fire is established and stabilized in the combustion chamber, the ignition system will be put out of service.
The most critical process in normal turbine operation is to manage the combustion and produce a proper amount of high-pressure exhaust gas. This exhaust gas is applied to the turbine blades and after rotating the turbine shaft, conducted to the exhaust stack.
This was the simplest way to address major parts of Gas Turbines and as one of the most sophisticated man-made machines, a Gas Turbine deserves more elaboration.
Also, there are different technologies which some manufacturers use as their proprietary technology and were not considered in this video.

To be more efficient, many gas plants use a combined cycle where the exhaust gas that leaves the gas turbine, which is still hot, is used to boil water and power a steam turbine to make even more electricity.

So I need air and heat added to the fuel. Air is let into the gas turbine through air intake and mixed with a proper amount of natural gas. The air/gas ratio is determined based on the specific heating value of the gas and quality of the air, amount of moisture, altitud from sea level and so on. Now an ignition system steps in and makes the initial sparks, whereby heat is provided. When the fire is established and stabilized in the combustion chamber, the ignition system will be put of service. The most critical process in normal turbine operation is to manage the combustion and produce a proper amount of high-pressure exhaust gas. This exhaust gas is applied to the turbine blades and after rotating the turbine shaft, conducted to the exhaust stack. With this quick review of key components of a gas turbine, I think it is time to decrease the altitude and elaborate on the system further. As mentioned earlier, air is let into the gas turbine through air intake. The air is prone to contaminations or having some unwanted particles which can harm the system and degrade the overall performance. The screening and filtration are basic requirements for incoming air. Also, proper instrumentation is mounted on the Air duct to monitor the draft oressure and temperature. In harsh enviroments, the air might need to be preheated or conditioned. Also, differential pressure monitoring of air filters. will warn the turbine operator of filter clogging. The conditioned air is conducted into the turbine air compressor which is an axial compressor comprised of multi-stages of blades mounted radially on the turbine inlet shaft. The discharge pressure and temperature of the air compressor are monitored to manage the combustion quality at the combustion chamber. Fuel gas is a key factor in the desing and operation of a gas turbine. The manufacturers need to know the details of fuel gas and only based on its characteristics, can guarantee the performance of their gas turbines are monitored during normal operation of a gas turbine. There are different technologies in propierly mixing the air and gas and making efficient combustion from manufacturer to manufacturer. Combustion chambers are of some tubular heat resistant structures and fuel is usually injected into it from the circumference and at different cross-sectional locations. The temperatures at different locations of the combustion chamber are thoroughly monitored by means of proper sensors like thermocoples. This high-temperature/high-pressure zone in gas turbine structure is of the highest levels of importance to monitor and control. Also, the technologies used in the design and construction of the combustion chamber are of the topmost ones. Now thet the air/gas mixing is well managed and combustion is going on properly, there is a plenty amount of hig-pressure/high-temperature exhaust gas generated and should be applied to the gas turbine blades to make turbine exit shaft rotation feasible. At this stage, the high RPM of gas turbine rotor should be tightly monitored and based on the load driven by turbine, the surge of turbine gets the topmost importance for turbine performance and turbine protection. Vibrations (axial and radial and speed) both at the air compressor and gas turbine should be continuisly taken into consideration. This was the simplest way to addres major parts of gas turbines and as one of the most sophisticated man-made machines, a gas turbine deserves more elaboration. Also, there are different technologies which some manufacturers use as their propierly technology and were not considered in this video.

Intento acercarme a un turbogenerador de gas para sentir mejor el tema. En una planta de energía de turbina de gas, hay un generador que es una máquina eléctrica. Pero para generar electricidad, este generador necesita un motor primario que, por ejemplo, es una turbina de gas. La turbina de gas transforma la energía química en el combustible en energía mecánica. La energía mecánica generada por el eje de salida de la turbina se transfiere a través de una caja de engranajes al eje del generador. Ahora mi generador puede generar energía eléctrica. Esta forma primitiva de energía eléctrica normalmente tiene un nivel de voltaje bajo o medio y para manejar mejor la pérdida de energía en las líneas de transmisión, este voltaje debe incrementarse mediante transformadores elevadores. Tales transformadores dan un nivel adecuado de voltaje a la energía eléctrica que se transmitirá a través de las líneas de transmisión y se entregará a la red. Después de esta breve descripción general de una aplicación de turbina de gas de muestra, voy a profundizar en el mecanismo de la turbina de gas con más detalle. Primero, imagine un cohete en el que se quemará algo de combustible y creará un gas de escape a alta presión. Según la ley de conservación de energía, la energía química del combustible se transforma en energía mecánica en el gas de escape a alta presión. Cuando se dispara un cohete, el empuje de este gas de escape mueve el cohete hacia adelante. Esta cantidad de ciencia de cohetes es suficiente para mí y ahora supongo que arreglo el cuerpo del cohete con una estructura mecánica robusta para evitar su movimiento. ¿Lo que sucederá? El gas de escape a alta presión debe liberarse y no tendrá más remedio que retroceder. Ahora tenga en cuenta esta estructura e imagine que coloco un conjunto de álabes de turbina en el camino de este escape de alta presión con retroceso. Usted ve que la liberación de energía mecánica que está mayormente en dirección "lineal" hacia atrás se transformará principalmente en una especie de "rotación" del eje de la turbina y hasta ahora he dicho que es un gran éxito, es decir, transformar la energía química del gas combustible en Energía mecánica rotacional del eje de la turbina. Ahora tengo un "Prime Mover" para mi generador en el ejemplo de planta de energía anterior. Además, este concepto de motor principal se puede usar en diferentes aplicaciones como turbocompresores o similares. Ahora que tengo los conceptos básicos de las turbinas de gas, centrémonos en una turbina de gas moderna y sus componentes. Lo más probable es que sepa sobre "Triángulo de fuego" o "Triángulo de combustión" que ilustra los ingredientes necesarios del fuego o la combustión, es decir, "Combustible", "Aire" y "Calor". Para transformar la energía química del gas combustible en energía mecánica, el combustible debe quemarse en la cámara de combustión de una turbina de gas, por lo que necesito agregar aire y calor al combustible.

The Gas Turbine applied to Turbo Generators (GTG) is very useful to produce electricity, to comply with the above first needs to transform the chemical energy of the fuel into mechanical energy, ie, this is obtained by combining air and heat with fuel in the "combustion chamber", and this by means of an electrical generator is converted into alternating current.

I've got a slight nitpick @ 1:49 The voltage doesn't decrease from the the distribution line to the home by itself. That diagram in real world conditions would fry every piece of electronics in a house. The voltage is decreased by step-down transformers at a substation; which isn't pictured there. And then it's stepped-down again by another transformer positioned on a pole somewhere along your street.

@realpars 2 ай бұрын

You're absolutely correct in pointing out the varying voltage levels from the power plant, ranging from 69,000 to 765,000 depending on transmission distance. Eventually, this voltage is brought down through a step-down transformer to a more usable 240/120 range. While this video focuses specifically on "What is a Gas Turbine?", we truly appreciate your interest in discussing voltage in more detail. Your input means a lot to us. If you're keen on exploring voltage further, we have a range of short videos dedicated to the topic on our RealPars KZfaq channel that you might find engaging and informative.

This is a great video. I will point out however, that around 7:36 they make you believe that firing temperature is measured directly by thermocouples. It isn’t. Typically the firing temperature is measured quite indirectly by being calculated from the exhaust temperature thermocouples and other sensors such as ambient temperature. I don’t know of any (at least heavy duty Frame 6, 7, 9) that measure firing temperature directly anywhere near the combustor or combustor to turbine transition piece.

@realpars 4 жыл бұрын

You are correct. In the video, the important point mentioned is still valid: monitoring of the temperature is critical to proper control of the turbine. Incoming gas temperature can be measured via thermocouple, but more modern methods have been employed due to velocity errors and the lag inherent in thermocouple measurements. For the actual combustion chamber temperature measurement, other direct and indirect methods must be used due to the nature of the combustion gasses, the high temperatures, and the high velocities.

Hey Ahmed, There is one same shaft which has connected all three devices together (Turbine, Compressor, and Generator). So if the Turbine increases the RPM, then this speed will be transferred to the Generator as well.

You are an engineer working for a manufacturer of land-based gas turbines. These turbines are similar to jet engines, but they are used on land to provide power for electricity generation and gas compression pipeline applications. Suppose that you would like to apply a ceramic-based thermal barrier coating to the turbine blades in the first-stage turbine to increase the operating temperature and efficiency of the engine. (a) What difficulties might engineers experience in trying to design a ceramic coating that will be applied to a super alloy metal blade? (b) What properties should be taken into consideration when choosing a suitable ceramic material for a coating? Be as thorough as possible.

is there any other uses for exhaust gases once they have left the system? Do they recirculate for heating or leave to atmosphere?

@realpars 4 жыл бұрын

The exhaust gases can be recovered to make steam or transfer the sensible heat to other process streams. A good example is the Linden Co-Generation Plant, which is a 940-MW electric power plant with five natural-gas-fired turbines. The waste heat is used to superheat water to steam that is distributed to New York City through a labyrinth of tunnels which supply 30 billion pounds of steam per year to over 100,000 buildings in NYC. This plant is quite an engineering marvel and an integral part of the utility infrastructure of NYC.

May I have a question? I wondering that have any plants use pure Oxygen instead of air to increase efficiency?

@realpars 3 жыл бұрын

Great question! The answer is "no", since the turbine would not be able to do useful work in a pure O2 environment. Nitrogen in the intake air is being employed as a process gas, which helps to get useful work from the combustion process. By being heated and accelerated in the combustor, it does the main work of driving the turbine and turning heat into mechanical work. A pure O2 stream would just combust, limiting the amount of useful work.

Kindly if anyone knows.. what is the instrument or device that is used to balance between gas feed and turbine speed?

@realpars 4 жыл бұрын

Typically, a control valve is used to regulate the gas flow to a Gas Turbine. These arew highly-specialized pilot-driven valves that are positioned based on sophisticated control algorithms which take into account temperature and pressure of the fuel inlet, air inlet, and combustion chamber. Since the cross-sectional geometry of the turbine and the rotor blade design is fixed, speed control is dependent on gas velocity control. Velocity can be affected by temperature, pressure, air humidity, fuel quality and fuel injection pattern. Gas turbine control must take all of these factors into consideration.

Which engine is this Gas Turbine Engine diagram based on? I'm kind of confused; At which section do the intake air & the injected fuel get mixed? According to your diagram, there is no way for the intake air on its flow path (compressor -> whatever middle section mean -> turbine) to meet the injected fuel.

@realpars 3 жыл бұрын

The Gas Turbine Engine highlighted in this video is a representation of a typical gas turbine (4:50 in the video). Lots of similar diagrams here: duckduckgo.com/?q=types+of+gas+turbines&atb=v216-1&iax=images&iai=https%3A%2F%2Fs-media-cache-ak0.pinimg.com%2F736x%2F58%2F0c%2F6d%2F580c6d0cc6053005cf6af48f40b2f892.jpg&ia=images The air intake (on the left) is compressed in the first section of the turbine. This is the flow shown in blue. Gas is injected (top and bottom, middle of the turbine). This is the yellow/orange flow. The gas and air meet in the combustion chamber and the hot gasses rotate the larger turbine blades. This is a simplistic representation of a complex piece of equipment, but is a typical representation.

@realpars 7 ай бұрын

Thank you for your query. Gas turbine engineering is designed to maximize fuel efficiency. Typically, in this engineering process, the heat generated by turbines is repurposed to heat a boiler, producing steam that powers an additional generator to generate electricity. Numerous original equipment manufacturers (OEMs) implementing turbines often adopt this technology.

What is the difference between turbocharger based generator & gas turbine based! Which is profitable & why!!?

@realpars 8 ай бұрын

Thank you for your inquiry. According to industrial standards, I'll provide definitions for both devices you mentioned in your question. However, determining which one is more profitable is complex, as it hinges on geographical location and the engineering intricacies of their designs. Turbocharger: A turbocharger, when added to a basic generator gas engine, incorporates an air compressor utilized in internal combustion engines to augment the volume of air entering the engine. This enhances its efficiency and power output by enabling the engine to burn more fuel through the increased air volume in the combustion chamber, thereby boosting overall performance. Turbine Engine: In contrast to a turbocharged engine, a turbine engine-also referred to as a gas turbine-generates mechanical power by harnessing energy from a rapid flow of hot combustion gases.

Not a bad idea in theory, but no, air needs to be supplied from the atmosphere. Often, we use combustion fans to increase the volume of air available, but it would be prohibitively expensive to "produce air" in the proper N2/O2 ratios.

Why wouldn't they pre-heat, the incoming air by the exhaust, to increase efficiency and decrease fuel consumption?

@realpars 3 жыл бұрын

Very large gas turbines may have economizer sections where waste heat is reused, but part of controlling the efficiency in the combustion chamber is control of the incoming air and fuel streams. Normally, the bulk of the energy in the turbine exhaust has been converted to work (rotating the turbine) and the residual heat is not easily captured or able to be reused. It is a matter of the economics of doing so, as well as space limitations where these engines are used.
