The innovation of gas turbines has transformed how industries generate power and operate machinery. These advanced machines convert fuel into mechanical energy, offering reliable power solutions across various sectors.

By understanding how gas turbines work, the different types available and their functions, businesses can make informed choices for effective machinery support and improved operational efficiency.

What is a gas turbine?

A gas turbine is a mechanical device that transforms the chemical energy from fuel into mechanical energy through a high-temperature combustion process. This generated energy powers equipment such as generators, compressors, and pumps.

Gas turbines play an important role in operating exploration and production facilities, which is crucial in industries like oil and gas. The engineering sector also relies on gas turbines for continuous power in different processes, while steel fabrication plants use them to sustain consistent production operations.

Different types of gas turbines

Gas turbines are designed to meet the needs of various sectors. Here are the main types and their uses:

1. Industrial gas turbines

Industrial gas turbines are built for heavy-duty operations, making them ideal for manufacturing environments. Facilities involved in steel fabrication rely on these turbines to ensure a continuous power supply, which is crucial for operating large machinery and maintaining production schedules. Their robust design allows for long operating hours with minimal maintenance interruptions.

2. Aero-derivative gas turbines

Derived from aircraft engine technology, aero-derivative gas turbines are lightweight and offer quick installation and mobility. These features make them suitable for temporary or mobile power generation, particularly in remote oil and gas fields. Their ability to operate on various fuel types provides flexibility for industries requiring adaptable energy solutions.

3. Marine gas turbines

Marine gas turbines are essential for powering naval vessels and commercial ships. They provide efficient propulsion and generate onboard electricity, ensuring smooth operations during long voyages. The compact size and high power-to-weight ratio of these gas turbines make them perfect for marine environments where space and efficiency are priorities.

4. Power generation gas turbines

Used primarily in power plants, these gas turbines produce electricity for residential, commercial, and industrial applications. Their ability to deliver reliable power ensures precision in energy distribution, which is vital for operations requiring stable energy, such as data centres and large manufacturing plants.

How gas turbines work

Gas turbines operate through a three-stage process that converts fuel into usable energy:

1. Air intake

The process begins with drawing in ambient air through an intake system. The air passes through filters to remove debris before entering the compressor, where it is pressurised to prepare for combustion.

2. Combustion

Inside the combustion chamber, the compressed air mixes with fuel, which then ignites to initiate the combustion process. This controlled combustion process produces high-temperature, high-pressure gases that expand rapidly, generating the force needed to drive the turbine blades.

3. Power generation

The expanding gases pass through a series of turbine blades, causing them to spin. This mechanical energy powers generators, pumps, or compressors, depending on the application. The exhaust gases can also be used in combined-cycle systems to improve overall efficiency.

Different functions of gas turbines in industries

Gas turbines perform several key functions across different sectors:

• Oil and gas

They power drilling equipment, pumps, and compressors, supporting exploration and production activities in onshore and offshore environments.

• Steel fabrication

Gas turbines provide the continuous energy needed to operate heavy machinery, maintain production lines, and support high-temperature processes.

• Engineering

They serve as reliable energy sources for a range of applications, from backup power systems to primary electricity generation.

• Precision in energy

Industries that require consistent energy outputs, such as manufacturing and data processing, benefit from the gas turbines’ stable power supply.

• Machinery support

Gas turbines enhance overall operational efficiency by providing dependable and backup power for essential equipment.

Benefits of using gas turbines

Investing in gas turbines offers several advantages for industries:

• Efficiency

They deliver high energy output with quick start-up times, reducing operational delays.

• Reliability

Gas turbines ensure continuous operation, which is essential for industries with around-the-clock production schedules.

• Fuel flexibility

They can operate on various fuels, including natural gas, diesel, and kerosene, making them adaptable to different energy sources.

• Space-saving design

Their compact size is suitable for facilities where space is limited.

• Environmental compliance

Modern turbines meet strict emission standards, supporting sustainable operations.
