Põlemisfaasi

Põlemisfaasi refers to the combustion phase, a crucial stage in the process of burning fuel. This phase is characterized by the rapid chemical reaction between a fuel and an oxidizer, typically oxygen, which releases heat and light. In a typical combustion event, the põlemisfaasi follows the preceding phases of ignition and initial flame propagation. During this phase, the majority of the fuel is consumed, and the energy release rate is at its peak.

The efficiency and characteristics of the põlemisfaasi depend on several factors. These include the type of fuel, its physical state (solid, liquid, or gas), the supply of the oxidizer, and the ambient conditions such as temperature and pressure. In engines, for instance, the põlemisfaasi is carefully controlled to maximize power output and minimize emissions. In uncontrolled fires, it represents the period of most intense burning and potential hazard. Understanding the põlemisfaasi is essential for fields ranging from fire safety engineering to the design of combustion engines and industrial furnaces. It is the stage where the primary transformation of fuel into energy and combustion products occurs.
