What is the autoignition temperature of diesel?
210deg C
What is the flash point and autoignition temp of kerosene?
The flash point of kerosenes is between 35 0C and 65 0C. The autoignition point of kerosenes is 220 0C.
What chemical has the lowest autoignition temperature?
At -20C, triethylborane is the low-temp autoignition champ. Its primary use? Setting other things on fire!
What concentration for H2 autoignition point?
The autoignition temperature of hydrogen (H2) is approximately 500 °C (932 °F). However, the concentration of hydrogen in air that can lead to autoignition ranges from about 4% to 75% by volume. Within this range, hydrogen can ignite spontaneously when exposed to sufficient heat, making it crucial to manage concentrations in various applications to prevent accidents.
How does increasing oxygen impact autoignition temperatures?
Increasing oxygen concentration can lower the autoignition temperature of a fuel-air mixture. This is because more oxygen is available for combustion, leading to faster and more complete fuel oxidation, which can decrease the temperature required for spontaneous ignition.
What is the difference between autoignition and flash point in terms of the ignition properties of a substance?
Autoignition is the temperature at which a substance will ignite without an external ignition source, while flash point is the temperature at which a substance will produce enough vapor to ignite when exposed to an ignition source. In summary, autoignition is spontaneous ignition, while flash point is the temperature at which a substance can ignite when exposed to a flame or spark.
What is autoignition temperature of hydrogen?
The autoignition temperature of hydrogen is approximately 500°C (932°F) in air. This is the temperature at which hydrogen gas will spontaneously ignite without the need for an external ignition source.
When dystopian novel gets its name from the autoignition temperature of paper?
Celsius 233. Or was that in BTU's.....
How do you melt magnesiun without autoignition?
I suppose that that best method is melting in an inert gas atmosphere.
What is the spontaneous combustion of the charge commonly caused by low octane fuel or excessive compression ratio?
Autoignition
Why petrol should high autoignition temp?
Petrol should have a high autoignition temperature to enhance engine efficiency and safety. A higher autoignition temperature reduces the risk of pre-ignition and knocking, which can lead to engine damage and reduced performance. Additionally, it allows for better control over the combustion process, ensuring that fuel ignites only under optimal conditions. This characteristic helps improve fuel economy and emissions by promoting more complete combustion.
Why do you think the autoignition temperature of paper is 451 degrees F when Wikipedia says it's 450 degrees C?
The autoignition temperature of paper can vary depending on factors such as the type of paper and its composition. The 451 degrees F value you mentioned may represent a common estimation for some types of paper while Wikipedia's 450 degrees C value could be based on a different study or source. It's important to consider multiple sources and understand the context when researching specific values like autoignition temperatures.
