Description

Technical Field

[0001] The utility model relates to the technical field of burners, in particular to a burner protection device. Background Art

[0002] Burners are a general term for devices that spray fuel and air in a certain way for mixed combustion. Burners are divided into industrial burners, burners, civil burners, and special burners according to their types and application areas. The function of a burner is to atomize the sample through flame combustion: the atomized test liquid enters the burner, and under the action of the flame temperature and flame atmosphere, it undergoes processes such as drying, melting, evaporation, and dissociation to produce a large number of ground state atoms, as well as some excited state atoms, ions, and molecules.

[0003] A burner is usually equipped with a flamethrower when in use to prevent damage to the equipment due to excessive temperature at the burner outlet. At the same time, the high-temperature flame generated by the burner is ejected from the flamethrower at high speed, which can enhance the combustion gas circulation in the furnace and improve the temperature uniformity in the furnace. However, the current burner flamethrower is usually directly exposed to the outside world without any protective measures. Since the burner flame is ejected through the flamethrower, the temperature of the flamethrower is relatively high. Even after use, the flamethrower will still maintain a high temperature. The high temperature will generate heat waves and the surrounding temperature will also rise sharply, thereby affecting the surrounding personnel and posing certain safety hazards. For this reason, we propose a burner protection device. Utility Model Content
