O estudo da combustão: uma revisão de literatura

Abstract

Introduction: combustion is defined as a chemical reaction between fuel and oxidant, releasing energy in the form of heat and light. This reaction is crucial in several sectors, such as transportation, electricity generation, industrial processes, among others. Therefore, the study of combustion becomes relevant for optimizing industrial processes, controlling pollutant emissions, increasing energy efficiency and operational safety. Objective: seek scientific evidence about the combustion process. Method: the literature review adopted a systematic approach to gather, analyze and synthesize several relevant sources on the topic of combustion. The search was conducted in academic databases and official pages of bodies associated with the Brazilian government. 41 works were selected based on criteria of methodological quality, relevance and contribution to the topic. The data was organized by themes and subthemes, followed by a comparative analysis to identify gaps, trends and consensus in the literature. The information was then synthesized to provide a comprehensive overview of current knowledge on the subject. All sources were duly cited and referenced in accordance with academic standards, maintaining academic integrity and avoiding plagiarism. Results: the study of combustion was divided into eight topics and their respective subtopics: Combustion; Combustion reagents; Excess air; Spontaneous combustion; Flash point, combustion and ignition; Flame structure; Calorific value and; Combustion products. Conclusions: the selected scientific evidence offered a broad view of combustion, highlighting its importance in energy generation, transport systems and industries, in addition to highlighting negative impacts such as environmental pollution and health risks.
