Inorganic chem: bunsen burner

Bunsen burner

• Is a widely used laboratory gas burner

• It operates by safely burning a continuous stream of flammable gas such as natural gas (mainly methane) or liquefied petroleum gases like propane and butane

• It is simple yet effective design allows for precise control over the flame

Parts and functionality of the bunsen burner

gas control valve

The quantity of gas admitted to the burner can be adjusted by the?

collar

The air is controlled by turning the?

barrel

Combustion occurs in the?

complete combustion

In __________ the fuel burns in abundant amount of oxygen, producing carbon dioxide, water and heat

Incomplete combustion

____________ occurs when there is not enough oxygen to allow the fuel to react completely to produce carbon dioxide and water, hence along with carbon dioxide and water, unburned carbon and carbon monoxide are also formed.

Types of laboratory burners

Tirrill Burner

• Is an advanced burner featuring both air and gas adjustment valves

• Is particularly useful in experiments requiring delicate heating control or varying flame characteristics

Meker Burner

• Is lab burner type designed to produce and even hotter and more uniform flame than the bunsen or tirrill burners

• This burner is ideal for heating substances requiring very high temperatures of longer heating durations
