Jet engines primarily use a refined form of crude oil known as aviation turbine fuel (ATF), which includes Jet A and Jet A-1 types. These fuels are derived from kerosene, a fraction of crude oil, and are specifically designed to meet stringent performance and safety standards required for aviation. The refining process removes impurities and enhances properties like freezing point and combustion efficiency, making them suitable for high-altitude flight.
A simple-cycle gas turbine used for power generation has a thermal efficiency of about 34 percent. Since 1 kwh is theoretically equivalent to 3,415 Btu, the simple-cycle gas turbine has a fuel connsumption of: 3,415 / 0.34 = about 10,000 Btu/kwh. Given the heating value (i.e, heat of combustion) of a fuel, we can easily calculate the simple-cycle gas turbine fuel usage. For example, natural gas has a net heating value of about 21,500 Btu/pound. Thus, the natural gas consumption in a simple-cycle gas turbine would be: 10,000 / 21,500 = 0.47 pounds/kwh = 0.21 kg/kwh. As another example, a typical diesel oil has a net heating value of 130,000 Btu/gallon. Thus, the diesel oil consumption in a simple-cycle gas turbine would be: 10,000 / 130,000 = 0.077 gallon/kwh. (The gallon used just above is the U.S. gallon rather than the Imperial gallon) A combined-cycle gas turbine will have a higher thermal efficiency and, hence, lower fuel consumptions.

1.Turbine output is increased for same compressor work. 2.As more heat is supplied,thermal efficiency decreases.
by calculating the inlet steam enthalpy-outlet steam enthalpy we will know the total kcal consumed for output mw required kcal for 1 kwh=860 now campare this with your turbine kcal for 1kwh now you came to know how much is your turbine efficiency................................................................................
This fuel has density approx 0.75 kg/liter, which is 1.65 lb/liter

The Airbus A320 uses Jet A / Jet A-1 type fuel
Jet fuel is a type of aviation-fueldesigned for use in aircraftpowered by gas-turbine. It is clear to straw-colored in appearance. The most commonly used fuels for commercial aviation are Jet A and Jet A-1 which are produced to a standardized international specification. The only other jet fuel commonly used in civilian turbine-engine powered aviation is Jet B which is used for its enhanced cold-weather performance.Jet fuel is a mixture of a large number of different hydrocarbons. The range of their sizes (molecular weights or carbon numbers) is restricted by the requirements for the product, for example, the freezing point or smoke point. Kerosene-type jet fuel (including Jet A and Jet A-1) has a carbon number distribution between about 8 and 16 carbon numbers; wide-cut or naphtha-type jet fuel (including Jet B), between about 5 and 15 carbon numbers.jet-fuelRead more: jet-fuel
There are many types of fuels used for aircraft. there are aircraft that run on normal unleaded and diesel fuels but the typical aviation only fuels are avgas (usually leaded 100 octane or 130/110), Avtur (aviation turbine), Jet-A and Jet A-1. these are the typical fuels you will find. Avgas is mainly used in general aviation whilst most airliners/jets use jet-a1.
The Boeing 757 typically uses Jet A or Jet A-1 aviation fuel, which is a kerosene-based fuel optimized for turbine engines. The aircraft has a maximum fuel capacity of approximately 11,489 liters (3,035 gallons), allowing for a range of about 3,900 nautical miles, depending on the specific model and configuration. Efficient fuel management and consumption are crucial for maximizing range and operational cost-effectiveness.
Airplanes typically use aviation fuel, which is a specialized type of fuel with different grades such as Jet A and Jet A-1 for commercial aircraft, and Avgas for smaller general aviation planes. These fuels are distinct from standard gasoline or diesel used in cars.
Plane fuel is commonly referred to as aviation fuel. The two main types are Avgas, used primarily in piston-engine aircraft, and Jet A or Jet A-1, which are used in jet engines. These fuels are specially formulated to meet the performance and safety requirements of aviation.
All types of Airbus, including the A330, use standard aviation fuel known as 'Jet A' in North America and 'Jet A-1' in the rest of the world.
Most large aircraft that have turbine-powerd engines use a fuel called Jet A. Jet A is basically highly refined kerosene. Jet A is used in the United States, Jet A-1 is used in the rest of the world. Where extreme cold conditions exist, Jet B is used for its better cold weather performance. Other aircraft that have reciprocating (piston) engines use Aviation gasoline, which is similar to what is used in automobiles.
Kerosene and wide cut aviation fuels differ primarily in their composition and intended use. Kerosene, specifically Jet A and Jet A-1, is a type of aviation fuel derived from refined crude oil, designed for turbine engines, and has a higher flash point, making it safer for aviation. Wide cut fuels, on the other hand, consist of a broader range of hydrocarbon chains and can include components from both kerosene and gasoline, which may be used in specialized applications or certain types of aircraft. The main distinction lies in their boiling points, volatility, and performance characteristics tailored to specific engine requirements.
Aviation fuel is commonly referred to as jet fuel for jet engines, with Jet A and Jet A-1 being the most widely used types. For piston-engine aircraft, aviation gasoline (often abbreviated as avgas) is used, with 100LL (low-lead) being a popular grade. These fuels are specifically formulated to meet the performance and safety requirements of aircraft engines.
