Classification and Industry Application of Burners
Burner is a general term for devices that mix fuel and air injection and burn in a certain way. Burners are divided into industrial burners, civilian burners, and special burners according to their types and application fields. It is often made of corrosion-resistant and high-temperature materials such as stainless steel or titanium metal. The function of the burner is to atomize the sample through flame combustion.
Under the action of flame temperature and flame atmosphere, the atomized test solution enters the burner and undergoes drying, melting, evaporation, dissociation and other processes to generate a large number of ground state atoms, as well as some excited state atoms, ions and molecules. A well-designed burner should have characteristics such as high atomization efficiency, low noise, and stable flame performance to ensure high absorption sensitivity and measurement accuracy.
Slot burner is usually used in atomic absorption spectroscopy to generate atomic vapor. The length and width of the burner gap vary depending on the type of gas used and auxiliary gas used. Generally, applicable gas and auxiliary gas are marked on the burner. Burners can be divided into three types based on the different fuels burned: coal powder burner, fuel burner, and gas burner.
Burners can be divided into fuel burners and gas burners based on fuel; According to the object of use, it is divided into kiln burners and boiler burners; According to the application field, it can be divided into industrial burners, civilian burners, and special burners. Among them, fuel burners are divided into light oil (such as diesel) and heavy oil burners (such as waste oil), while gas burners are divided into natural gas burners, liquefied gas burners, urban gas burners, biogas burners, etc. The burner we usually refer to refers to the boiler burner.
