Liquid fuels work by undergoing a three-step process: vaporization, mixing with oxygen, and combustion. This process allows liquid fuels, whether in pools or sprays, to release energy through burning.
The Three-Step Process of Liquid Fuel Combustion
Here's a breakdown of how liquid fuels burn:
-
Vaporization: The burning process begins when the liquid fuel transforms into a gaseous state through vaporization. According to the provided reference, "The burning processes start with the vaporization of the liquid fuel." This is essential because combustion reactions primarily occur between gases.
-
Mixing with Oxygen: Once vaporized, the fuel vapor needs oxygen to burn. "Next, the fuel vapor is mixed with oxygen," as indicated in the reference. This mixing is critical for a sustained and efficient burn.
-
Combustion Reaction: The actual burning happens when the fuel vapor and oxygen mixture reaches its ignition temperature. "Finally, the combustion reaction takes place." This chemical reaction releases heat and light, which we perceive as fire.
