What is the flame temperature of ethanol?
What is the flame temperature of ethanol?
The auto ignition temperature (AIT) is recorded for stoichiometric concentrations. The AITs for methanol and ethanol are 470 °C and 365 °C, respectively [31]. These liquids are therefore not as easily ignited by hot surfaces as long chained hydrocarbon, e.g., diesel with an AIT of 210 °C.
What is the adiabatic flame temperature of a fuel?
When a combustion reaction takes place energy is released to the combustion products. If no heat is lost in this process, the temperature of the combustion products is known as the “Adiabatic Flame Temperature.” 2,328 K or 2055 C.
What is the adiabatic flame temperature of methane?
For example, the adiabatic flame temperature for methane is around 2326 K at constant volume and 2236 K at constant pressure.
What is the temperature of ethanol?
As we mentioned, the boiling point of pure ethanol is 174 degrees F.
Which gas has the highest adiabatic flame temperature?
II. A Thermodynamics of Combustion
| Fuel | State | Adiabatic flame temperature, maximum (K) |
|---|---|---|
| 3080 | ||
| Carbon monoxide | Gas | 2400 |
| Methane | Gas | 2220 |
| 2270 |
What is adiabatic temperature rise?
The adiabatic-temperature rise is simply the increase in temperature caused by a specified reaction yielding specified products in a circumstance such that all the heat released by the reaction (assuming an exothermic reaction for such calculations) is retained in the system and is used to heat up the products–there …
What temp does ethanol evaporate?
The boiling point of ethanol or grain alcohol (C2H5OH) at atmospheric pressure (14.7 psia, 1 bar absolute) is 173.1 F (78.37 C).
Does ethanol burn hotter?
Ethanol burns hotter than gasoline and that could damage engine parts.
