What You Need to Know About Gas Turbines

Gas turbines produce a steady and consistent level of electricity and remain popular in many markets. However, before purchasing or operating one for your purposes, it is crucial to understand them more profoundly.

Let’s take an in-depth look at gas turbines, how they work, and what kind of devices use them.

Understanding Gas Turbines

Gas turbines are also known as combustion turbines, as they use continuous and internal combustion to produce a steady supply of power. They come in a variety of different types. The two types of land turbines include heavy frame engines and aero-derivative engines. However, many more exist in a variety of other realms.

The parts in an average turbine include:

  • Upstream rotating gas compressor to move fuel properly
  • A combustor where the gas is ignited to produce power
  • A downstream turbine that works on the same shaft as the compressor
  • Efficient elements that help to keep the engine running smoothly

The Brayton Cycle

This design works on what is known as the Brayton cycle. This method compresses air and then mixes it with fuel at extremely high temperatures. This burning helps to produce a gas that spins the turbine blades very quickly. Next, the blades turn the driveshaft to power the generator. The generator has a magnet that, when turned, causes electrons to move and produces electricity.

Devices that use this method include:

  • Many types of jet engines, particularly those with high-speed operation
  • Trains that need a steady and consistent supply of moving power
  • Ships that need efficient operation over a large travel area
  • Diverse arrays of electrical generators that use gas to convert power
  • Gas compressors and pumps that help keep many devices operational
  • Tanks of many different types, especially those with a high volume

These gas turbines can produce an incredible amount of power while operating. For example, the GE 7F.05 can create 225 MW or 644,000 horsepower as it works. Just how much power is that? Imagine 644 Formula One car engines running simultaneously and powering the exact vehicle at the same time.

That kind of raw power makes this a popular option for jet engines, turboprop engines, and an auxiliary power unit for large buildings or organizations. Make sure that whatever device you’re using is appropriate with your machine before upgrading to this turbine.
