Luminous and Non-Luminous Flame
Luminous Flame:
- A luminous flame is a type of flame that emits light.
- It is typically yellow or orange in color.
- Luminous flames are generally produced by combustion processes that release a significant amount of soot or unburned carbon particles.
- These carbon particles heat up and emit light, giving the flame its characteristic glow.
- Examples of luminous flames include candles and gas stoves.
Non-Luminous Flame:
- A non-luminous flame is a type of flame that does not emit light.
- It is usually blue in color and is much hotter than a luminous flame.
- Non-luminous flames are produced by combustion processes that are efficient and complete, resulting in minimal soot or carbon particles.
- These flames burn cleanly and efficiently, making them ideal for applications where high heat is required without the presence of soot.
- Examples of non-luminous flames include Bunsen burners and gas torches used in welding.
In summary, luminous flames emit light and are typically yellow or orange in color due to the presence of soot or carbon particles, while non-luminous flames do not emit light and are usually blue in color, indicating a clean and efficient combustion process.
