Computation of adiabatic flame temperature - YouTube

The constant-pressure adiabatic flame temperature of such substances in air is in a relatively narrow range around 1950 °C. 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.

With these conceptual ideas it is possible to develop simple graphs that give the adiabatic flame temperature of any hydrocarbon fuel in air at any equivalence ratio [10].Such graphs are shown in Figures 1.3, 1.4, and 1.5.These graphs depict the flame temperatures for a range of hypothetical hydrocarbons that have heats of formation ranging from −1.5 to 1.0 kcal/g (i.e., from −6.3 to 4.2

Combustion - Wikipedia

Combustion, or burning, is a high-temperature exothermic redox chemical reaction between a fuel (the reductant) and an oxidant, usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke.Combustion does not always result in fire, because a flame is only visible when substances undergoing combustion vapourise, but when it does, a flame is a
