At what temp does jet fuel burn?
Both Jet A and Jet A-1 have a flash point higher than 38 °C (100 °F), with an autoignition temperature of 210 °C (410 °F).
Jet engine fuel burns at temperatures of close to 3,000 degrees Fahrenheit. Jet engine fuel is derived from a fraction of crude oil, which is known as kerosene.
Once vaporised, however, jet fuel is extremely flammable and burns at a much higher temperature than other fuels.
In its gaseous form, Propane gas combustion has a higher adiabatic flame temperature (by approximately 0.764%) than Jet A fuel [2].
| Fuel Gas | Max Temperature |
|---|---|
| Acetylene | 3300°F |
| Propane | 2800°F |
| Hydrogen | 2650°F |
| MAPP® | 2900°F |
Sparks and static electricity can easily ignite gasoline fumes. Aviation fuels fall mainly into two categories, aviation gasoline - commonly abbreviated to “avgas” - and the variants of paraffin (kerosene) used by all gas turbine engines and loosely described as "jet fuel".
Jet fuel can actually be used in cars, but only in diesel engines. Kerosene jet fuel and diesel are actually similar enough to allow for cross-functionality and would provide a similar performance.
There are still some big differences between diesel and Jet-A. For starters, there's a higher level of sulfur and other additives-including cetane, and the cetane number-in Jet-A than is allowed in your diesel. This could lead to fines and may even damage your engine.
Jet A fuel costs less than 100LL (avgas) fuel because it is less complicated and expensive to manufacture, less expensive to transport via pipelines, and used in significantly higher quantities leading to economies of scale.
What is the Standard Weight for Jet Fuel in Gallons? As a rule of thumb, one US gallon of jet fuel weighs about 6.47-7.01 pounds at 59°F. Reversing the calculation tells us that one pound of jet fuel is equal to about 0.143-0.155 US gallons.
How much jet fuel is produced from a barrel of oil?
The 42-gallon oil barrel was officially adopted in 1866. Today, a barrel's refined products include about 20 gallons of gasoline, 12 gallons of diesel and four gallons of jet fuel (and rocket fuel) and other products like liquefied petroleum gases and asphalt.
| Fuel grade | Color | Usage |
|---|---|---|
| AVgas 100LL | Blue | Most light piston engine aircraft |
| AVgas 82 UL | Purple | Most light piston engine aircraft |
| JET A/A1 | Straw or clear | Turbine/ Diesel aircraft |
| Diesel/Biodiesel | Clear | Diesel aircraft |
The flash point of kerosene is between 37 °C (99 °F) and 65 °C (149 °F), and its autoignition temperature is 220 °C (428 °F). The freeze point of kerosene depends on grade, with commercial aviation fuel standardized at −47 °C (−53 °F).
The melting point of steel ranges from 2500-2800°F or 1371-1540°C.
JP-8 is the military equivalent of Jet A-1; however, it contains a corrosion inhibitor and anti-icing additive that is not required in the ASTM specification of Jet A-1. The primary difference between the two military fuels is that the flash point temperature for JP-5 is higher (60°C) as compared to JP-8 (38°C).
