When powdered charcoal is exposed to a non-luminous flame, it undergoes combustion. The heat from the flame ignites the charcoal, causing it to react with oxygen in the air, resulting in the production of carbon dioxide and heat. This process can also produce carbon monoxide if there is insufficient oxygen. The flame may appear brighter as the charcoal burns, and it will eventually turn to ash as it is consumed.
When powdered charcoal is sprayed onto a flame, the color of the flame may turn a bright orange or yellow due to the carbon particles burning and emitting light. The charcoal acts as a fuel source, enhancing the combustion process and intensifying the color of the flame.
Sprinkling charcoal in a flame will cause the flame to change colors. This is apparent in fireworks displays, which routinely use charcoal.
Non-luminous flame
A non-luminous flame is typically used in laboratory settings when using a Bunsen burner. This flame produces a more controlled and homogeneous heat source, making it ideal for processes like heating, sterilizing, and combustion analysis. The non-luminous flame also produces less soot and is more energy efficient compared to a luminous flame.
For cooking, a non-luminous flame is generally better than a luminous flame. A non-luminous flame produces higher temperatures and more efficient combustion, resulting in faster and more even cooking. Luminous flames, on the other hand, are typically cooler and can leave soot on cookware, which may affect the taste and appearance of the food.
Sprinkling charcoal powder into a non-luminous flame will not change the color of the flame. The flame color is determined by the elements present in the fuel being burned, not by adding additional substances like charcoal.
If you spray charcoal onto a non-luminous flame, the charcoal will burn due to the presence of oxygen in the flame. The heat from the flame will cause the charcoal to ignite and combust, creating a bright and hot flame.

Non-luminous flame should be used for heating in the laboratory because the flame is steady and produce little or no soot.Non-luminous flame is very hot thus, it is recommendable to use for laboratory purposes.Luminous flame is unsteady while non-luminous flame is steady.Another reason of using non-luminous flame because the flame of non-luminous is blue, and not visible unlike the luminous flame which is yellow in colour and visible.
-A non-luminous flame is when the air hole of the Bunsen burner is closed but a luminous flame is produced when the air hole is opened.-A luminous flame has an outer of orange colour and an inner of blue. A non-luminous flame has an outer of blue and an inner of orange.-A luminous flame produces soot while a non-luminous does not produce soot.-A luminous flame is weak and unsteady. A non-luminous flame is strong and steady.-A non-luminous flame is very hot while a luminous flame is not too hot.
The degree of a luminous flame is 100 degree .

Turning a luminous flame to a non-luminous flame when not in use conserves fuel because non-luminous flames burn more efficiently. A non-luminous flame produces less soot and smoke, making it safer and better for indoor air quality.
Non-luminous flame should be used for heating in the because the flame is steady and produce little or no soot. Non-luminous flame is very hot thus, it is recommen- dable to use for laboratory purposes. Luminous flame is unsteady while non-lumi- nous flame is steady. Another reason of using non-luminous flame because the flame of non-luminous is blue, and not visible unlike the luminous flame which is yellow in colour and visible.
A luminous flame is produced when a chemical reaction (such as combustion) releases energy in the form of light. The presence of solid particles or molecules in the flame can also contribute to its luminosity by emitting light as they are heated. This is different from a non-luminous flame, which does not produce visible light.
A sooty flame is typically considered a non-luminous flame because it does not produce significant visible light. It appears dark or dim due to the presence of unburned carbon particles (soot) in the flame.
The two kinds of flames produced by a Bunsen burner are the luminous flame (yellow flame) and the non-luminous flame (blue flame). The luminous flame is cooler and produces soot, while the non-luminous flame is hotter and ideal for heating and sterilizing.
