A combustion process without heat loss or gain is called adiabatic.. Adiabatic flame temperatures for some common fuel gases like hydrogen, methane, propane and octane - with oxygen or air as oxidizers in a constant pressure adiabatic reaction - are indicated below:
15. 5 Adiabatic Flame Temperature For a combustion process that takes place adiabatically with no shaft work, the temperature of the products is referred to as the adiabatic flame temperature. This is the maximum temperature that can be achieved for given reactants.

Archived from the original on 7 January 2008; Temperature of a blue flame and common materials; Calculators. Online adiabatic flame temperature calculator using Cantera
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. Figure 6.1 is a typical graph of flame temperature for a natural gas–air mixture. As percent ...
Adiabatic Flame Temperature of Octane as a Function of Fraction of Air This application will calculate and plot the flame temperature of octane for a varying amount of air. Temperature-dependent thermodynamic properties are calculated with the ThermophysicalData:-Chemicals package.
Adiabatic flame temperature. Quite the same Wikipedia. Just better. To install click the Add extension button. That's it. The source code for the WIKI 2 extension is being checked by specialists of the Mozilla Foundation, Google, and Apple. You could also do it yourself at any point in time.
Adiabatic Flame Temperatures - Adiabatic flame temperature hydrogen, methane, propane and octane - in Kelvin; Butane - Dynamic and Kinematic Viscosity - Online calculators, figures and tables showing dynamic and kinematic viscosity of liquid and gaseous butane, C 4 H 10, at varying temperarure and pressure, SI and Imperial units
Example: Adiabatic Flame Temperature for Propane Combustion Consider the combustion of propane with 250% theoretical air. What is the maximum temperature this process can achieve? Assume that the reactants enter the combustion chamber at 25 °C and 100 kPa. Solution: We must begin by writing our general combustion equation for propane.
Adiabatic Flame Temperature - The opposite extreme of the above example in which we evaluated the enthalpy of combustion is the case of an adiabatic process in which no heat is released. This results in a significant temperature increase in the products of combustion ...
