When the adiabatic flame temperature is maximum?
The adiabatic flame temperature is one that occurs when the combustion chamber is well insulated with no heat losses (adiabatic conditions). The peak adiabatic flame temperature occurs at around Φ = 1 in an ideally insulated combustion chamber.
Which gas has highest adiabatic flame temperature?
Common flame temperatures
|Pentane ( C 5H 12)||Air||3591|
|Propane ( C 3H 8)||Air||3596|
What is maximum flame temperature?
|hydrogen||2,660 °C (oxygen), 2,045 °C (air)|
|MAPP||2,980 °C (oxygen)|
|methane||2,810 °C (oxygen), 1,957 °C (air)|
|natural gas||2,770 °C (oxygen)|
Why is the maximum adiabatic flame temperature located at slight fuel rich side?
Since the extent of dissociation is greater on the lean side as a result of the stoichiometry of dissociated products, the peaking occurs on the rich side.
Why is the temperature of a flame lower than the adiabatic flame temperature?
Its temperature is lower than the constant volume process because some of the energy is utilized to change the volume of the system (i.e., generate work).
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 temperature rise?
Maximum increase in temperature that can be achieved. This increase only occurs when the substance or reaction mixture decomposes completely and at adiabatic conditions.
Does adiabatic flame temperature increase with pressure?
The results indicate that adiabatic flame temperature is weakly correlated with pressure. The adiabatic flame tempera- ture increases only by about 50 ºC as a result of 30 bar pressure increase.
What is the significance of adiabatic flame temperature?
It is used to determine suitability of fuel for an application. It is used Determine extent of substitution of a lower quality fuel to converse higher quality fuel. The is adiabatic flame temperature is very important in design and scale-up procedures wherever heat transfer is a significant consideration.
