The constant-pressure adiabatic flame temperature of such substances in air is in a relatively narrow range around 1950 °C. You can change your ad preferences anytime. . This is because, in terms of stoichiometry , the combustion of an organic compound with n carbons involves breaking roughly 2 n C–H bonds, n C–C bonds, and 1.5 n O 2 bonds to form roughly n CO 2 molecules and n H 2 O molecules. An initial view of the concept of adiabatic flame temperature is provided by examining two reacting gases, at a given pressure, and asking what the end temperature is. The adiabatic flame temperature is one that occurs when the combustion chamber is well insulated with no heat losses (adiabatic conditions). Learn more. The process is shown schematically in Figure 15.3 , where temperature is plotted versus the percentage completion of the reaction. 53. conditions.
