Abstract

A new characteristic temperature, the "adiabatic limit flame temperature", has been proposed in this paper; it is an inherent temperature of a combustible mixture based on the thermochemical properties of the constituents. The concept of this temperature is very important, especially when considering a combustion system with energy recirculation between products and reactants. Since this is the highest temperature attainable in a combustion system without any auxiliary energy input, the available energy and the efficiency of the system should be estimated based on this temperature, instead of on the adiabatic flame temperature. An illustrative example of a system of reaction between diatomic molecules is shown, and the characteristics of the temperature are discussed. The low calorific limit of flammability is also discussed in this paper.
