Document Summary

Bunsen burner one of the heating devices used in laboratory (alcohol lamp, furnace). Bunsen burner produces heat energy as a result of combustion of gaseous fuel. Hydrocarbon component of gaseous fuels and oxygen gas will mix in the barrel and produces flame. The flame produced depends on the proportions of the amount of gases. If there is a sufficient amount of oxygen gas, combustion process is complete, producing non-luminous flame. Insufficient amount of oxygen causes incomplete combustion and the flame is luminous. Barrel where the oxygen and gas fuel mix. Collar control the amount of air entering the barrel. Air inlet allows the air to enter the barrel. Gas spuds limits the supply of gas to the barrel. Gas inlet where the gas enters the burner. Luminous flame also known as safety flame. Produce when there is insufficient amount of air. Produce when there is sufficient amount of air.
