Evaluation of thermodynamic parameters of low-gaseous pyrolants

摘要

Thermodynamic analysis of combustion parameters of low-gaseous pyrolants is performed. Two reactive oxidizers of potassium nitrate (KNO_3, KN) and potassium perchlorate (KClO_4, KP) are considered. Zirconium (Zr) and boron (B) are considered as high energetic metallic fuels. Temperature and energetic effectiveness of KN/B, KN/Zr and KP/B, KP/Zr mixtures are investigated. Zirconium is considered as an additive leading to remarkable high temperature of products, in comparison to other metallic additives. Thermodynamic evaluations are performed with MWEQ program package that in particular is able to evaluate of chemical substances that are present in the reactive mixture in trace abundances. Several components in condensed (state or fluid) phases may be acquainted simultaneously. The paper is intended to interpret base effects that appear by changing/rising addition of metallic fuels to inorganic oxidizers.
