What is a blue flame burner?
A natural gas blue flame indicates that the burner is providing the correct air-fuel mixture, with sufficient oxygen for complete combustion at the burner. A blue flame burns the fuel completely producing carbon dioxide, water and heat.
What is the hot blue flame called?
Propane flames are blue with yellow tips. The hottest fires are from oxyacetylene torches (about 3000 degrees Centigrade) that combine oxygen and gas to create pinpoint blue flames.
Why is the blue flame the hottest?
Blue flames have more oxygen and get hotter because gases burn hotter than organic materials, such as wood. When natural gas is ignited in a stove burner, the gases quickly burn at a very high temperature, yielding mainly blue flames.
What is a blue flame used for?
A blue gas flame colour means complete combustion. This indicates that the gas is being burned efficiently without any unburned and wasted gas. With complete combustion you get the maximum heat output from your gas and use less gas to generate heat with whatever appliance you are using.
Is there a hotter flame than blue?
Is there anything hotter than blue fire? You just can’t get a fire hot enough to burn blue. Stars that are blue-white are around 20,000 K, hotter than any flame we can create on earth.
What are the hazards of a bunsen burner?
Bunsen burners present fire hazards. They produce an open flame and burn at a high temperature, and as a result, there is potential for an accident to occur.
What is a bunsen burner and its function?
A Bunsen burner, named after Robert Bunsen, is a common piece of laboratory equipment that produces a single open gas flame, which is used for heating, sterilization, and combustion.
How does a bunsen burner produce a flame?
One of the most familiar instances of a luminous flame is produced by a Bunsen burner. This burner has a controllable air supply and a constant gas jet: when the air supply is reduced, a highly luminous, and thus visible, orange ‘safety flame’ is produced. For heating work, the air inlet is opened and the burner produces a much hotter blue flame.
How do you set up a bunsen burner?
1. Turn on bunsen burner. 2. Use metal tongs to hold copper wire at the centre of the orange/yellow part of the flame. 3. Use a stopwatch to time how long it takes for the copper wire to glow red. 4. Record the time. 5. Repeat steps 2-4 with the copper wire held at the outer blue flame and the inner blue core.
