What are the features of a Bunsen burner?

A Bunsen burner is made entirely of metal. In order to function properly, Bunsen burners must have a barrel (A) that’s approximately five inches long, a collar (B) with air holes (C), a gas intake (D) and gas valve (E) and a stand (F) to keep all of the pieces from making contact with a work surface.

What is the advantage of Bunsen burner?

this tends to be the first port of call in a chemistry laboratory. The Bunsen burner is a convenient way to apply heat in a variety of situations. The flame can be adjusted to a luminous yellow when not being used which makes them safer as it gives added visibility.

What two safety features should be followed when using a Bunsen burner?

Safety advice when using a Bunsen burner

• Always light the splint before turning on the gas.
• Always inspect the Bunsen burner, tubing, and gas valve before use.
• Tie back long hair and do not wear loose long sleeves.
• Use tongs when holding objects in a flame.
• Never leave a lit Bunsen burner unattended.

Which type of flame is good for heating Why?

A blue 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.

What is the function and uses of Bunsen burner?

A Bunsen burner, named after Robert Bunsen, is a kind of gas burner used as laboratory equipment; it produces a single open gas flame, and is used for heating, sterilization, and combustion. The gas can be natural gas (which is mainly methane) or a liquefied petroleum gas, such as propane, butane, or a mixture.

Which of the following are correct safety points when using a Bunsen burner quizlet?

Terms in this set (14) Always light the match or lighter before turning on the gas. Always follow proper procedures for lighting and using a Bunsen burner (see procedure). Use tongs when holding objects in a flame. Never leave a lit Bunsen burner unattended.

What safety equipment do you need to use a Bunsen burner?

Before lighting, place the Bunsen burner at least 12 inches in front of any overhead shelving or equipment and be mindful of loose hair or clothing, like your lab coat. Always keep safety equipment, like fire extinguishers and safety blankets, close at hand.

What do you need to know about the Bunsen burner?

Bunsen burner, device for combining a flammable gas with controlled amounts of air before ignition; it produces a hotter flame than would be possible using ambient air and gas alone. It consists of a metal tube on a base with a gas inlet at the lower end of the tube. The air and gas are forced to the top of the tube.

What is the purpose of the gas control valve on a Bunsen?

Adjusting the gas valve on the Bunsen burner changes the volume of gas flow; the more gas entering the burner, the larger the flame. The collar at the base of the barrel contains air holes to control the amount of oxygen reacting with the gas.

How does A Meker and Fisher Bunsen burner work?

With too much air, the flame may burn inside the burner tube; that is, it may strike back. The Meker and Fisher burners, variations of the original Bunsen burner, have metallic grids to increase the turbulence of the mixture and keep the flame at the top of the tube.

Can you turn on a gas tap without a Bunsen?

Never turn on a gas tap without a Bunsen attached and a match lit above the barrel. Extinguish the match immediately after lighting it. Always leave it on the yellow safety flame when you are not heating anything. Always leave it on the blue heating flame when you are heating something.
