Gas Turbine Types: Overview of Types and Profitable Applications

The four major types of gas turbine engines are discussed here. In the aviation sector, the most common propulsion technology is the aircraft turbine engine. There are different varieties of turbine engines, each with its own unique set of maintenance and overhaul requirements. As a result, choosing the correct business to do repairs and maintenance on your aircraft turbine engine is critical. Keep in mind that such a wide range of gas turbine designs can only be found in aircraft gas turbines. The configuration of gas turbines used in power plants is similar to that of turbojet engines, which will be addressed later.

Turbojet Engines

Turbojet engines were the first form of the gas turbines. Even though they don’t seem like reciprocating engines, they work on the same principle: intake, compression, power, and exhaust. Air is pushed at a rapid rate to the fuel inlet and ignitor of the combustion chamber in this type of engine. By expanding air, the turbine causes faster exhaust gases.

Turboprop Engines

A turboprop engine is the second type of gas turbine. It is a turbojet engine with a propeller coupled via a gear system. The operation of a gas turbine of this sort is as follows:

  • A shaft connected to a transmission gearbox spins while the turbojet spins.
  • A transmission box slows the spinning process, and the transmission mechanism is coupled to the slowest moving gear.
  • The air propeller spins, creating thrust.

Turbofan Engines

Turbofan engines are combined with the world’s top turbojets and turboprops. A duct fan can link a turbofan engine to the front of a turbojet engine. The fan then provides an extra push, which aids in cooling and decreases engine noise.

Turboshaft Engines

Turboshaft engines, the fourth gas turbine type, are mostly employed in helicopters. The most significant distinction is that turboshaft engines use the majority of their power to spin turbines rather than propel them out the back. A turbojet engine with a big shaft attached to the back is known as a turboshaft engine.

Components of a Gas Turbine Engine

Propulsive thrust can be generated using a gas turbine engine. In the case of a pure jet engine, this can power a generator, pump, or propeller while also creating thrust through the nozzle. While the gas turbine engine is a basic system, due to the high operating temperatures and strains, components for a powerful machine must be carefully constructed and produced from expensive materials. As a result, gas turbine engines are often limited to big units where they are cost-effective. A compressor (takes in and compresses the air), combustor (applies fuel to the air and ignites it), turbine (converts high-speed gas energy into rotary power through expansion), gearbox and shaft (provides rotary power to the driven devices), and exhaust nozzle are the main components of a gas turbine (runs out of the turbine part the low emissions of spent gas).

Gas turbine gearboxes are widely used in today’s gas turbine designs. Based on the turbine’s rotational speed and power output, this component is responsible for effectively delivering the turbine’s produced power to the moving parts. However, recent versions use direct drive, which means there is no gearbox inside the gas turbine engine and the turbine rotational power is sent directly to where it is needed.

Gas turbine control system

The gas turbine control system monitors and safeguards the gas turbines. With integrated control system solutions, you may get superior performance for a connected plant. It scales and adapts to changing requirements in thermal and renewable power generation, oil and gas, and safety applications with ease. IS200VCMIH1B and IS200VCRCH1B are some examples of GE control system parts.

Lithium-ion battery

Lithium-ion battery

A lithium-ion battery or Li-ion battery is a type of rechargeable battery. Li-Ion batteries have one of the highest energy densities of any battery technology today. Compared to the other high-quality rechargeable battery technologies (nickel-cadmium or nickel-metal-hydride), Li-ion batteries have a number of advantages. In addition, Li-ion battery cells can deliver up to 3.6 Volts, 3 times higher than technologies such as Ni-Cd or Ni-MH. Li-ion batteries have no memory effect, a detrimental process where repeated partial discharge/charge cycles can cause a battery to ‘remember’ a lower capacity.

The lithium-ion battery has an anode and electrode, as well as an electrolyte in three main components. Li-Ion Battery uses lithium ions as a key component of its electrochemistry. In the battery, lithium ions move from the negative electrode to the positive electrode during discharge and back when charging.

When a Li-ion battery is charged, lithium ions are removed from the cathode electrode. The decomposition of lithium ions then travels through the electrolyte and transfers into the anode electrode, and the energy is stored in a lithium-ion battery during this cycle. When the Li-Ion Battery stop storing, the lithium ions move back to the cathode electrode; and the stored energy has been released. The selection of cathode and anode materials is very important, and this is the main focus of various researchers

A prototype lithium-ion battery was developed by Akira Yoshino in 1985, based on earlier research by John Goodenough, M. Stanley Whittingham, Rachid Yazami, & Koichi Mizushima during the 1970s–1980s, and then a commercial Li-ion battery was developed by a Sony and Asahi Kasei team led by Yoshio Nishi in 1991.

The Lifespan Of Lithium-Ion Battery

The typical lifespan of a lithium-ion battery is around 2-3 years or 300-500 charge cycles. One charge cycle is calculated as the period of use from fully charged to discharged and fully recharged once again.

Li-Ion batteries are now an important part of our daily. By powering our mobiles, TV remotes, Laptops, Toys, Electric Scooters, Electric Cars, and Solar Power. Using Li-ion batteries helps to reduce carbon effects by reducing the usage of fossil fuels and saving the environment.

Currently, the bestselling electric cars, the Nissan Leaf and the Tesla Model S, both use Li-ion batteries as their primary fuel source.

Top Tips for Making the Transition to Remote Working

Once a niche idea for only a certain type of person, remote working, exacerbated by the coronavirus crisis and the real need for people to stay at home, it looks like it is here to stay. Due to the flexibility and privacy, it offers you, it might be something that you are actually interested in. Perhaps you have already been offered a job within the remote working sphere. If this sounds familiar, then you are in the right place, as this guide has actually been created in order to give you the essential overview when it comes to making sure that have you a successful transition to remote working.

Move Somewhere With Cheaper Cost of Living

If you are working remotely, this means that basically, time zone notwithstanding, you can live anywhere that you want in the world. This means that you should be taking advantage as much as you can by moving somewhere with a much cheaper cost of living. The main point here that you have to take into consideration is the cost of relocation, especially when it comes to vehicles and pets.

 If you have a dog that you need to move to a new place, then you should look around for a great dog transport service that can offer you a reasonably-priced dog taxi. Additionally, be careful about moving to another country, as the USA still has a double-tax law, meaning that you could end up losing money if you move abroad.

Keep the Schedule

Remote work does offer flexibility, but it can also offer confusion. This is why it doesn’t work for a fair amount of employees, who prefer the hustle and bustle of the office. Nonetheless, just because you are not physically in the office, this doesn’t mean that you have to throw the schedule in the trash. Instead, what you need to do is to devise a schedule that actually works for you. By having that fixed idea of what you should be spending your time on, you will then find yourself working a whole lot better as a result.

Ask For a Remote Work Budget

Working remotely for a lot of companies is not just as simple as opening your laptop in bed. Instead, they have to make sure that their remote work employees are properly set up to do their job. This requires having a lot of different technology involved. Nonetheless, if you are hired on a full-time remote contract, it should not be your responsibility to fork out the money involved in this type of relocation.

Instead, ask clearly and firmly to the company you are working for to give you the money needed to set up remotely. If they cannot commit to giving you the money that you need, then you should probably take your skills elsewhere, as this is actually a sign that they are actually a company that doesn’t truly understand the different emotional and technological needs that are involved with remote work.
