Characteristics of luminous flame?
Non luminous zone is the zone of a flame which is also the hottest zone of the flame as it is mostly in contact with oxygen. It is also called invisible zone.
What are the disadvantages of luminous flame?
A luminous flame is not suitable for heating as it gives out soot (A black powdery or flaky substance consisting largely of amorphous carbon, produced by the incomplete burning of organic matter).
Does a non luminous flame produce a lot of carbon residue?
Yes, it does produce more carbon.
What are the advantages of using a non-luminous flame?
Non- Luminous can burn efficiently because luminous flames don't burn as efficiently as non-luminous ones, they don't produce as much energy. This means that the non-luminous flames have a lot more energy than luminous ones, and their flames are actually hotter. This is why the luminous ones look yellow and the non-luminous ones look blue. Hotter flames burn blue and (relatively) cooler ones burn yellow.
Why is it bad to burn foam seat cushions in your wood stove?
When foam burns it produces a lot of noxious chemical byproducts. A lot of these are toxic and can cause respiratory distress or even death.
Why is a Bunsen burner not used for heating when the air hole is closed?
When the air hole is closed, the flame is a luminous flame. This flame is not ideal for heating for the following reasons: it is not as hot as the non-luminous flame it is very unstable it produces a lot of soot thus, only non-luminous flames (the blue one) is ideal for heating. :)

Why does the black soot formed?
A small stable flame of a candle has a lot less black smoke than a larger flickering flame. Air around the burning candle causes this to happen.
Why kerosene flame yellow in color?
On a Goff Petroleum publication Kerosene Health and Safety Data Sheet ( www.goffpetroleum.co.uk/filespdf/kerosene_datasheet.PDF ) it says Premium Grade Kerosene may be dyed blue or pink.
How do you get blue flame to yellow flame?
You reduce the supply of fuel. A "yellow" flame is a lot cooler than a "blue" flame. As it pertains to Chemistry, the dominant color for a nonluminous flame (yellow) is blue.
How does a peanut maintain a flame?
It has a lot of oil in it.
Why do you have to use the yellow flame when not using the Bunsen burner?
You don't have to use the yellow flame but its not recommended for heating as its a lot cooler than the blue flame.
What is the difference between premixed and diffusion flame?
Two main different combustion regime: diffusion flame is generated when fuel and oxidizer are provided separately and then mixes with each other and reacts in the mixing zone; while premixed flame is generated when fuel and oxidizer are totally mixed and goes to burning after ignition. The main difference is that premixed flame forms a propagating wave front and diffusion flame tends to be stable. Due to that, premixed flame is more sensitive to acoustics, i.e. flashback and blow-off. On the other hand, the mixing is a key factor for diffusion flame. If mixing is not enough, we suffers with high soot and unburnt hydrocarbon emissions. The flame thickness is different a lot, and premixed flame is much thinner. In terms of environment issue, NOx emission is relatively higher in premixed flame than in diffusion flame due to higher flame temperature. In application, safety is a main concern for premixed flame, so that stabilization is always applied in practice. Diffusion flame is more widely applied, especially on aircraft and power station.
What are some ideas to clean soot off tools after fire and water damage?
I have a lot of fire water damage from an incident last year in my basement. What are some good solutions for cleaning soot off of tools?
What produces sunlight?
Lot of sunlight
What does the eternal flame symbolize in Jewish?
It means you lot are idiots
