Burner is a general term for a device that makes fuel and air eject and burn in a certain way. Burners are divided into industrial burners, civil burners and special burners according to type and application field. It is mostly made of corrosion-resistant and high temperature resistant materials such as stainless steel or metal titanium.
The function of the burner is to atomize the sample through flame combustion. The atomized test solution enters the burner. Under the action of flame temperature and flame atmosphere, a large number of ground state atoms, as well as some excited atoms, ions and molecules are produced through the processes of drying, melting, evaporation and dissociation.
A well-designed burner should have the performance of high atomization efficiency, low noise and stable flame, so as to have high absorption sensitivity and measurement precision. Gap burners are often used to produce atomic vapor in atomic absorption spectrometry. According to the types of gas and auxiliary gas used, the length and width of the burner gap are different. Generally, the applicable gas and auxiliary gas are marked on the burner.
Burners can be divided into pulverized coal burners, oil burners and gas burners according to different fuels. Burner is also called burner, which can be divided into oil burner and gas burner according to fuel; It is divided into kiln burner and boiler burner according to the use object; According to the application field, it can be divided into industrial burner, civil burner and special burner.
