It depends on what you are using for a source and what you are heating, if in welding you would preheat your work piece with a rosebud torch tip using oxy-acetylene
A Tirrill burner is typically better for heating compared to a Meeker burner. Tirrill burners allow for more precise control of the flame intensity, making them more suitable for heating applications that require specific temperature adjustments.
A blue flame is typically used for heating as it produces higher temperatures compared to a yellow flame. Blue flames are also more efficient in transferring heat energy.
A non-luminous (blue) flame is ideal for heating solids as it provides a consistent and even heat distribution. A non-luminous flame is hotter than a luminous flame, making it more efficient for heating purposes. Additionally, it reduces the risk of leaving soot or unburned fuel residue on the solid material.
When you are temporarily not heating anything, you should use a safety flame or a low flame. This type of flame is small and controlled, reducing the risk of accidents and conserving fuel. It provides enough visibility to work safely without the intensity of a higher flame.
A blue flame is formed when the air hole on the Bunsen burner is open. The blue flame indicates complete combustion of the gas, with plenty of oxygen present for the reaction. This type of flame is hotter and more efficient for heating purposes.
Blue or heating flame.
A Bunsen Burner has an air hole at the base of the burner tube. When closed', the flame is bright yellow and slick. The flame is 'cool'. The yellow colur are white hot particles of carbon. When 'open,' the flame is pale blue and roaring. The flame is 'hot'. The pale blue colour is carbon dioxide being formed from atmospheric oxygen.
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 most stable flame is a blue flame (produced when air valve is open)
A roaring flame on a Bunsen burner is typically used for tasks that require very high heat output, such as quickly heating solutions or sterilizing equipment. This type of flame is characterized by a blue, cone-shaped inner flame surrounded by a slightly luminous outer flame.
A yellow flame in a Bunsen burner is called a reducing flame. This type of flame has incomplete combustion and can be adjusted to become a blue flame for more efficient burning.
The blue flame often called the roaring flame, burns at a higher temperature and is indicative of complete combustion. This type of flame is typically more efficient and produces less soot, making it ideal for tasks that require precise heating. In contrast, the yellow flame, known as the safety flame, burns at a lower temperature and is characterized by its characteristic yellow and orange hues. This flame is a sign of incomplete combustion, which can produce soot and other byproducts, making it less efficient for certain applications. The safety flame is often utilized in situations where a visible flame is important for safety, such as in gas stoves or heaters. The blue flame is called a roaring flame and the yellow flame is called the safety flame.
