A safety Bunsen burner flame is used primarily in laboratory settings for safe heating and sterilization purposes. It provides a controlled, adjustable flame that minimizes the risk of accidental fires or burns. This type of flame is ideal for tasks such as sterilizing instruments, heating liquids, or conducting experiments that require consistent and stable heat. Additionally, the safety features often include mechanisms to prevent accidental ignition and ensure proper ventilation.
Blue or heating flame.
To heat chemicals or substances in science lab for experiment. There is an air hole in the Bunsen burner where you can screw loose to have open air hole that is the blue flame which is hotter. When there is a close air hole then the flame would be orange in color which is not as hot compared to the blue flame.
The closed flame (orange) is only ever used when turning on the bunsen burner or when you are leaving it for any amount of time to insure the safety of your class mates. The open flame (blue) is used at all other times. Please note it can be hard to see the blue flame so it is important that you stay aware and safe as it is often as hot as 700oC.

They are generally used to hold objects like a small bowl that would be heated by something like a Bunsen burner, the bowl would be too hot to hold with hands.
you would use the safety flame when not heating anything because the blue flame is for heating because its hotter than yellow.
For heating water with a Bunsen burner, you would use a blue flame. This is the hottest part of the Bunsen burner flame and provides the most efficient heat transfer to the water.
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.
For boiling water, you would typically use a medium to high, blue, non-luminous flame on a Bunsen burner. Adjust the air hole to achieve the desired intensity of the flame.
you would produce radon gas.
The tip of the blue cone is the hottest part of the Bunsen burner flame.
To set the Bunsen burner flame for normal heating, start by opening the air hole at the bottom of the burner. Then light the burner and adjust the air hole until you achieve a stable blue flame with a light blue inner cone. This flame is ideal for general heating purposes. Adjust the flame height as needed by controlling the fuel and air mixture.
A properly adjusted flame on a bunsen burner would have a flame that is blue. It would also appear that there is a lighter blue flame in the center, usually referred to as an inner blue cone, the hottest part of the flame.
Blue or heating flame.
Most things in chemistry.. Usually you would use a blue Bunsen flame (half open at the bottom) for heating almost everything. The yellow flame is only a safety flame, as you can't see a blue one all that well, and it's not used for heating because it produces soot
To increase the height of a Bunsen burner flame, you can open the air valve to allow more air to mix with the gas before it ignites. This will result in a hotter and taller flame. Adjusting the gas flow rate higher can also increase the flame height.
The hottest flame on a Bunsen burner is typically the blue cone-shaped flame. You can adjust the air and gas flow to achieve this flame, which is characterized by a steady, roaring noise. To confirm the hottest flame, you could use a thermometer to measure the temperature at the tip of the flame.
