How hot do different fuels burn?
Flames can vary in temperature from about 600°C to more than 3000°C. One factor is the energy released from the fuel’s combustion. Acetylene, for example, burns very hot because of the triple bond between the carbon atoms in it.
What is the temperature of gas flame?
About 3,000 degrees fahrenheit for a gas flame.
What is the normal adiabatic flame temperature in air?
2,400 K
For hydrogen burning in air at 1 atmosphere the Adiabatic Flame temperature is 2,400 K or 2127 C.
What is the maximum temperature of flame reached when the fuel is burned?
The temperature of fire can range from around 400 degrees Fahrenheit up to 9000 degrees Fahrenheit (200 to 4980 degrees Celsius). The temperature will vary based on things like fuel source and oxygen content. There are even examples of “cold fire” that will not burn you.
How hot is an open flame?
Common temperatures
| Material burned | Flame temperature |
|---|---|
| Bunsen burner flame | 900–1,600 °C (1,652–2,912 °F) [depending on the air valve, open or close.] |
| Candle flame | ≈1,100 °C (≈2,012 °F) [majority]; hot spots may be 1,300–1,400 °C (2,372–2,552 °F) |
| Propane blowtorch | 1,200–1,700 °C (2,192–3,092 °F) |
What is the hottest flame?
Blue flames
Flames themselves change colour over time, and will usually have multiple colours in different parts of the flame. The hottest part of the flame is the base, so this typically burns with a different colour to the outer edges or the rest of the flame body. Blue flames are the hottest, followed by white.
What is the flame temperature of diesel fuel?
The ignition temperature of Diesel fuel No. 1 ranges from 450 to 602 Kelvin, Diesel fuel No. 2 ranges from 527 to 558 Kelvin, and Diesel fuel No . 4 is 536 Kelvin.
What is adiabatic flame temperature of a fuel?
The adiabatic flame temperature (AFT) is defined as the temperature attained when all of the chemical reaction heat released heats combustion products. In practical coal combustion systems, excess oxygen is usually applied to achieve complete coal burnout.
How hot does an open fire get?
A bonfire can reach temperatures as hot as 1,100 degrees Celsius (2,012 degrees Fahrenheit), which is hot enough to melt some metals.
Where is a flame the hottest?
The hottest part of the flame is the base, so this typically burns with a different colour to the outer edges or the rest of the flame body. Blue flames are the hottest, followed by white. After that, yellow, orange and red are the common colours you’ll see in most fires.
What is the temperature of a candle flame?
about 1,000 °C
On average, the flame temperature is about 1,000 °C (1,830 °F).
What is the coldest flame?
The lowest recorded cool flame temperatures are between 200 and 300°C; the Wikipedia page references n-butyl acetate as 225°C.
Is it possible to determine the flame temperature of a fuel?
Since most combustion systems use air as the oxidizer, it is desirable to be able to conveniently determine the flame temperature of any fuel with air at any equivalence ratio. This objective is possible given the background developed in this chapter.
What is the flame temperature of MAPP gas?
This is a list of flame temperatures for various common fuels. Adiabatic flame temperatures for common gases are provided for air and oxygen. For these values, the initial temperature of air, gas, and oxygen are 20 °C. MAPP is a mixture of gases, chiefly methyl acetylene, and propadiene with other hydrocarbons.
What is the flame temperature of propane and oxygen?
Flame Temperatures Fuel Flame Temperature oxyhydrogen 2,000 °C or more (3,600 °F, air) propane 2,820 °C (oxygen), 1,980 °C (air) propane butane mix 1,970 °C (air) propylene 2870 °C (oxygen)
Where does the maximum adiabatic flame temperature occur?
The maximum adiabatic flame temperature for a given fuel and oxidizer combination occurs with a stoichiometric mixture (correct proportions such that all fuel and all oxidizer are consumed). The amount of excess air can be tailored as part of the design to control the adiabatic flame temperature.
