Combustion Ideal vs Real Operation Analysis

Combustion is a process of active oxidation of combustible compounds such as:  carbon, hydrogen and sulfur.  Therefore, combustion is a chemical reaction.  High amount of heat is released during the combustion process.  Combustion has a high degree of importance in engineering.

Complete combustion at constant pressure with and without heat loss is presented.  Six different fuels (carbon, hydrogen, sulfur, coal, oil and gas) react with air as the oxidant at different stoichiometry values (stoichiometry => 1) and oxidant inlet temperature values.

Reactants and combustion products specific enthalpy values change with an increase in the temperature and such specific enthalpy values are presented in a plot where one can notice the flame temperature definition.  Physical properties of basic combustion reactants and products are presented in a specific enthalpy vs temperature plot.

The combustion technical performance at stoichiometry => 1 conditions is presented knowing the specific enthalpy values for combustion reactants and products, given as a function of temperature.  Combustion products composition on both weight and mole basis is given in tabular form and plotted in a few figures. Also, flame temperature, oxidant to fuel ratio and fuel higher heating value (HHV) are presented in tabular form and plotted in a few figures.  The provided output data and plots allow one to determine the major combustion performance laws and trends.
