COMBUSTION PROCESSES AND HEAT RELEASE
Keywords:
Combustion, heat release, exothermic reaction, heat of combustion, calorimetry, activation energy, chain reaction, flame, combustion rate, reaction kinetics.Abstract
Combustion processes and heat release phenomena involve a scientifically grounded analysis of combustion mechanisms in chemical thermodynamics and reaction kinetics, the elementary chemical reactions occurring within them, and the quantitative and qualitative aspects of heat release. Combustion is a complex physicochemical process in which a combustible substance (fuel) reacts with an oxidizing environment, releasing large amounts of thermal and light energy. This article provides a detailed examination of the thermodynamic foundations of combustion, the chain reaction mechanism, kinetic characteristics based on the Arrhenius law, the heats of combustion of various fuels, and their practical applications. Research results demonstrate that temperature, pressure, concentration, and catalysts critically affect combustion efficiency. The environmental aspects of combustion products and energy-saving prospects are also discussed.
