What is a gas turbine?

A gas turbine is an internal combustion engine that converts the kinetic energy of expanding gas (working fluid) into usable mechanical energy. It uses continuously flowing gas as the working fluid to drive the impeller to rotate at high speed, converting the energy of the fuel into useful work. It is an internal combustion power machine. It is a rotating impeller heat engine.

In the main process of air and gas in a gas turbine, there are only three components of the gas turbine cycle: compressor, combustor and turbine, which is commonly known as a simple cycle. Most gas turbines use a simple cycle scheme.

The working process of a gas turbine is that the compressor (i.e. compressor) continuously sucks air from the atmosphere and compresses it; the compressed air enters the combustion chamber, mixes with the injected fuel and is burned to become high-temperature gas, which then flows into the gas turbine. The medium expansion does work, pushing the turbine impeller to rotate together with the compressor impeller; the working capacity of the heated high-temperature gas is significantly improved, so while the gas turbine drives the compressor, there is still residual work as the output mechanical work of the gas turbine.

What are the application of gas turbines?

Gas turbines are widely used in many fields, including power generation, ship propulsion, military equipment, aerospace, and industrial and commercial applications. Gas turbine rotor manufacturers are making various efforts to adapt to market demand‌‌

In the field of power generation, gas turbines are efficient power generation equipment that can start quickly and adapt to load changes, so they are often used in power systems for peak shaving and backup power. In addition, gas turbines can also be combined with steam turbines to form a combined cycle power generation system to further improve power generation efficiency.

In terms of ship propulsion, gas turbines are widely used on modern ships, especially in the main engines of large ships. Marine gas turbines have the advantages of light weight, small size, and high power. They do not require a boiler and can directly drive the propeller.

In terms of military equipment, gas turbines are often used in tanks, armored vehicles and other vehicles to provide powerful power support. Its high-speed rotation allows the vehicle to move quickly and adapt to various complex terrains.

In the field of air transportation, heavy-duty gas turbines have demonstrated their outstanding performance. As the core of the propulsion system of aircraft, helicopters and other aircraft, the high power density and high efficiency of gas turbines provide powerful power support for aircraft. At the same time, its low emission characteristics also help reduce the impact on the environment and meet the requirements of the modern aviation industry for environmental protection and sustainable development.

In addition, gas turbines are also used in industrial and commercial fields, such as driving compressors, pumps and other equipment, and as power sources for air conditioning and refrigeration systems.

Why do gas turbines need filters?

Gas turbines are heavy machinery, and their normal operation cannot be separated from the maintenance of various filter elements.

The gas turbine filter element is an important part of the gas turbine. Its function is to filter out impurities and particles in the air ,making the gas sprayed through the gas turbine fuel nozzle assembly purer，to ensure the normal operation of the gas turbine. According to different application scenarios, gas turbine filter elements can be divided into different types such as gas filter elements, turbine filter elements and air compressor filter elements. The service life and performance of these filter elements have a great impact on the operating results and life of the gas turbine. In order to ensure the normal operation of the gas turbine, we need to replace the filter element regularly and select the appropriate filter element model and brand.
