The inlet temperatures of the fuel and oxidant streams individually are specified Two types of results are generated: (a) the adiabatic flame temperature with the equilibrium product species both with and without dissociation; and (b) with the products temperature specified then the heat transfer inside the combustor is calculated, on the basis

What is the adiabatic flame temperature if the entering air and fuel mixture are at 90 degrees F? This example comes from Robinson, Chemical Engineering Practice Set, 2nd Ed., Problem 6-5. However, the solution method is a little more elaborate and precise then the one presented by Robinson.
Adiabatic Flame Temperature. This page contains a spreadsheet demonstrating the classic adiabatic flame temperature calculation. With combustion processes, it is often necessary to either achieve a specified combustion temperature or avoid exceeding a high temperature limit.
Adiabatic Flame Temperature for Combustion of Methane Abstract This project calculated the adiabatic flame temperature of a combustion reaction of pure methane and oxygen, assuming that all of the heat liberated by the combustion reaction goes into heating the resulting mixture.
The heat capacities will be a function of temperature. The final temperature, the upper limit for the integrals, will therefore be the only remaining unknown. We can therefore solve for the adiabatic flame temperature using an appropriate solver. The solution obtained in Mathcad is shown 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. Heat transfer, incomplete combustion, and dissociation all result in lower ...
Adiabatic flame temperature calculation refers to the ignition procedure when there is no shaft movement taking place adiabatically. This is the most extreme temperature that can be accomplished for the given reactants. It is classified into steady volume adiabatic flame temperature and pressure adiabatic flame temperature.
Of course, the word “adiabatic” means no heat loss (or gain) to or from the surroundings, so if you enter a non-zero value in this cell, the flame temperature values is not an adiabatic one. However, it still can have practical meaning if you are interested in learning how the flame temperature varies with heat loss.
