Why is black soot formed when the flame is luminous?
The black deposit produced represents soot particles, heated to incandescence. It comes about when the combustion of air is insufficient.
Is the inner part of a luminous flame yellow?
Yes, the inner part of a luminous flame is typically yellow. The yellow color is due to the incomplete combustion of carbon particles present in the flame.
When do you get yellow soot in the burner flame?
Yellow soot is obtained when the holes of the burner are not clean. The combustion is incomplete. The yellow soot or yellow flame is because of unburnt carbon particles.
What is the composition of the deposit on the porcelain dish when it was held over a luminous flame?
The deposit on the porcelain dish from holding it over a luminous flame is likely a mixture of soot, carbon, and other combustion byproducts. This can result from incomplete combustion of organic materials present in the flame.
Why does a non luminous zone produce less residue as compared to a luminous one?
In the luminous zone of a flame solids such as carbon are produced because there is only a small supply of oxygen to burn the fuel. In the non-luminous zone there is more oxygen and the fuel is completely oxidised to gases such as carbon dioxide.
Is fuel consumption harmful to environment?
burning carbon fuels like wood,coal& pettroleum relaese unburnt carbon particles to the environment.THEY sometimes causes Respiratory diseases such as asthma.
Is sooty flame a luminous or non luminous?
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.
Why is black soot formed when the flame is luminous?
The black deposit produced represents soot particles, heated to incandescence. It comes about when the combustion of air is insufficient.
What does a catalytic converter do on a 1997 dodge 5.9l?
It converts carbon monoxide, nitrous oxides and unburnt fuel into carbon dioxide, nitrogen, and water vapor.It converts carbon monoxide, nitrous oxides and unburnt fuel into carbon dioxide, nitrogen, and water vapor.
Is the inner part of a luminous flame yellow?
Yes, the inner part of a luminous flame is typically yellow. The yellow color is due to the incomplete combustion of carbon particles present in the flame.
Why is a luminous flame formed when the air hole is closed?
The luminous flame is present when the air valve is closed because of an incomplete combustion process and the burning of trapped carbon (soot).
Why do spark pugs turn black?
Unburnt carbon
When do you get yellow soot in the burner flame?
Yellow soot is obtained when the holes of the burner are not clean. The combustion is incomplete. The yellow soot or yellow flame is because of unburnt carbon particles.
What is the name for bits of unburnt carbon?
charcoal graphite diamond
What can cause black carbon from the exhaust?
It would be unburnt fuel
How the flame produced when the air holes were closed. if the the flame was luminous what made it so?
When air holes are closed, oxygen supply decreases, leading to incomplete combustion and the production of soot particles. These soot particles can get heated up to incandescence and emit visible light, creating a luminous flame. The presence of carbon in the soot is what causes the flame to appear luminous.
Does smoke create rainbows?
Light passing through a transparent medium like glass/water does. Smoke is made of small particles of unburnt carbon, and light passing through is does not get split into a rainbow.
