Apr 18, 2023 · Given the fuel of the Burner burner is methane, when the air hole of a burner burner is fully opened, striking back will occur. I observed that the strike-back flame is green in colour and produces loud noises. Are there any reasons for the green flame colour and noises?
Sep 12, 2024 · 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.

If using matches, strike the head of the match against the striking strip on the back of the pack. Hold the flame up to the top of the Bunsen burner where gas is emitted until a flame appears. Adjust the size of the flame using the gas line knob or the stopcock as needed.
Feb 22, 2023 · Strike back Bunsen burner It is designed to be used in places where there is a risk of gas leaks. Has a special feature that prevents the flame from striking back into the burner tube.

The burner normally has a metal body and a solid base on the bench. Rubber tubing connects a lab bench’s gas nozzle to the burner’s primary gas inlet at the burner’s base. The ability of the gas (or other fuel) to combine with oxygen before the combination is ignited is crucial to the operation of the burner, i.e., producing an air-gas premix befor...
A Bunsen burner is made up of various parts, including: 1. Stand or base: The Bunsen burner is supported by the base, a broad and hefty component that comes in various shapes. It’s attached to a side tube known as a gas tube. It helps to place the burner on the bench. 2. Barrel or chimney:It is a base-attached vertical metal tube about 5 inches lon...
The two primary fuel sources for a Bunsen burner are natural gas (mostly methane) and liquefied petroleum gas (propane, butane, or a mixture of the two). A burner for one fuel type should never be used with another type of fuel. So, it’s necessary to make the right choice of the burner depending upon the fuel source.
Yellow flame
It is referred to as a safety flame since it’s easy to notice in a well-lit space. It can be produced when the air hole is completely closed, and it reaches temperatures of about 300 degrees.
Blue flame
When the air hole is just half opened, it becomes challenging to see in a bright environment. Such flame is known as blue flame, reaching temperatures of 500 degrees.
Roaring blue flame
It is the hottest flame produced when the air hole is completely open, and it can attain temperatures of 700 degrees.
Wear a lab apron and safety glasses. Long hair should be tied back if one has it.The rubber tube should be connected to a gas tap.When using a Bunsen burner on a surface that is not heat resistant, place a heating pad underneath it.A cover for the air hole should be placed on the collar.It is used to sterilize loops, needles, and flaming the mouth of test tubes during inoculations, mostly in microbiology laboratories.They are used for heat purposes, mostly in chemical laboratories.It is used in the dehydration of complexes, drying of salts, moisture analysis, and identification of water of crystallization.It helps to determine melting point using classical calorimetry and boiling point using thiele tube method.It is quite easy to handle.It can be utilized anywhere there is access to gas (coal gas, natural gas, etc.).The burner is available in various sizes, so we may pick one that works best for us.In addition to heating, we can utilize it for basic glass-blowing tasks and air drying.Fire risk exists constantly.It’s difficult to keep the temperature where you want it to be.This type of equipment is flammable and burns at a very high temperature, potentially resulting in an accident if not handled mindfully. Following are the points to be considered while operating the Bunsen burner are: 1. We must work in a space free of extraneous objects such as notebooks, paper, etc. 2. Long hair must be tied back, and loose cloth...
A. FIREBOY Safety Bunsen Burner
Features 1. Monitoring the flamestops gas leaks 2. Automatic ignition, requiring neither a lighter nor matches 3. Gas cartridge adapters: Independent of any gas delivery system 4. Optional battery: no external power source is required.
B. Bunsen acc. to Bunsen
Features 1. composed of non-corrosive materials 2. nickel-plated air regulation, 3. needle valve for gas type selection 4. both natural gas and propane can be suitable as a fuel source
C. Laboratory Bunsen burner 4056/B
Features 1. A new universal nozzle makes it possible to use it with any type of gas GPL and at any pressure. 2. A valve block and a sensor unit make up the thermocouple. This thermocouple is a safety mechanism that shuts off the gas flow if the flame goes out, preventing potential environmental gas saturation.
A Bunsen burner, named after Robert Bunsen, is a kind of ambient air gas burner used as laboratory equipment; it produces a single open gas flame, and is used for heating, sterilization, and combustion.
