Example of Adiabatic Flame Temperature Calculation. Problem Statement: Calculate the adiabatic flame temperature of liquid butane burned with 30% excess air. Both the air and liquid butane enter at 25 o C. Solution: First we will perform the mass balance calculations so that we know the number of moles of each component in the inlet and outlet ...
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.
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 ...
In the study of combustion, there are two types of adiabatic flame temperature depending on how the process is completed. These are constant volume and constant pressure, describing the temperature that the combustion products theoretically reach if no energy is lost to the outside environment.. The constant volume adiabatic flame temperature is the temperature that results from a complete ...
The adiabatic flame temperature is the temperature that would be achieved by a flame if the process of combustion took place in the absence of heat loss to the surroundings. In meteorology and oceanography , the adiabatic cooling process produces condensation of moisture or salinity and the parcel becomes oversaturated.
The adiabatic flame temperature is the temperature that would be achieved by a flame if the process of combustion took place in the absence of heat loss to the surroundings.” Short answer: In real life everything is an approximation, so the only real life examples of adiabatic processes are approximate.
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.
• To apply the energy balance to find the adiabatic flame temperature. • To use the heat-of-formation method to solve the energy balance. • To find the molar enthalpy of mixtures, while accounting for chemical reactions.

A mixture of 90% methane, 6% ethane and 4% nitrogen is burned with 30% excess air. 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.
