When you burn coal.
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.
CYCLOHEXANE - orange and blue flame with no soot....
Soot is the product of an incomplete combustion of carbon.
The black deposit produced represents soot particles, heated to incandescence. It comes about when the combustion of air is insufficient.
Soot.
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.
Soot appears when there is an incomplete combustion of carbon. In fact, soot is just carbon but floated up as it becomes less dense.
The black substance created by a yellow Bunsen burner flame is typically soot, which is carbon particles that have not fully combusted in the flame. The yellow color of the flame indicates incomplete combustion, leading to the production of soot as a byproduct.
When you burn coal.
A yellow, smoky flame with a flickering appearance typically produces more soot and smoke compared to a clean, blue flame. This is due to incomplete combustion, which occurs when there isn't enough oxygen present to fully burn the fuel. It's important to ensure proper ventilation and adjust the air-to-fuel ratio to minimize the production of soot and smoke.
Yes, a non-luminous flame can produce soot if the combustion process is incomplete. Incomplete combustion results in the formation of carbon particles, which make up soot. To reduce soot production, it's important to ensure proper ventilation and an adequate air-to-fuel ratio for complete combustion.
The yellow flame (or luminous flame) should not be used because 1. It is less hot that the blue flame (or non-luminous flame) 2. It produces soot, as compared to the blue flame which is the clean flame
