The non-luminous flame on a Bunsen burner, also known as the blue flame, is used for heating because it produces a high-temperature, clean, and efficient flame. This type of flame provides a consistent and focused source of heat that is ideal for tasks like sterilizing equipment, melting solids, or conducting chemical reactions.
The name is a "safety flame". This is when the air hole on the Bunsen burner is closed, resulting in a flame with a yellow, sooty appearance. It is used for low-temperature heating applications.
Leaving a Bunsen burner on a luminous flame when not in use ensures that the burner is ready for immediate use and prevents the need for constant relighting, saving time and gas. It also helps maintain a stable flame and prevents potential gas leaks from the burner.
To obtain a luminous flame on a Bunsen burner, adjust the air intake to decrease the amount of oxygen mixing with the gas. This can be done by partially closing the air hole at the base of the Bunsen burner. This will result in an incomplete combustion of the fuel, producing a yellow, sooty flame.
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. :)
Leaving the Bunsen burner with a luminous flame while not in use helps prevent gas leaks by indicating that the gas is on. It also maintains a constant temperature for when it needs to be used again quickly.
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
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.
you would use the safety flame when not heating anything because the blue flame is for heating because its hotter than yellow.
Yellow/Orange. The blue one is harder to see and hotter.
A blue, non-luminous flame is recommended for burning in a Bunsen burner. This flame is efficient for heating as it has a high temperature and is well-suited for various laboratory applications. Adjusting the air inlet controls on the Bunsen burner can help achieve the desired flame type.

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.
