In order to explore the best formula of flame-type high-energy burner, this paper selects 7 groups of flame-type high-energy burners with good stability, high energy and a wide range of raw materials based on the existing literature and patents. The Gibbs free energy Values of 7 groups of formulations at different temperatures were calculated by using the chemical thermodynamic formula, and the changes in Gibbs free energy Values of 7 groups of formulations were drawn, which provided a basis for the calculation of reaction rate k value by Eyring equation. Then, according to the calculation theory of chemical reaction calorific value, the heat of reaction of 7 different formulations at different temperatures was calculated. The results show that the Gibbs free energy value of Al/MnO 2 in the seven groups of formulations is much smaller than that of the other groups in the same reaction temperature environment, and decreases with increasing temperature. According to the Arrhenius formula and the Eyring equation, the reaction rate of Al/MnO 2 is the fastest in each group. When the other conditions are constant, the reaction enthalpy of Al/MnO 2 is the smallest in each group, therefor the heat released by the reaction is the most. In summary, under the same quality conditions, the Al/MnO 2 flame type high energy burner formulation has the fastest reaction rate and the most heat release, which provides theoretical guidance for experimental design and practice.
