Description

Technical Field

[0001] This utility model relates to the field of burner technology, and in particular to a boiler burner that prevents deposits and blockages. Background Technology

[0002] A burner is a general term for a device that sprays fuel and air in a specific manner for combustion. Burners are classified into several types based on their application: industrial burners, combustion engines, civil burners, and special burners. They are mostly made of corrosion-resistant and high-temperature-resistant materials such as stainless steel or titanium. The function of a burner is to atomize a sample through flame combustion. The atomized sample enters the burner, and under the influence of the flame temperature and atmosphere, undergoes processes such as drying, melting, evaporation, and dissociation, producing a large number of ground-state atoms, as well as some excited-state atoms, ions, and molecules. A well-designed burner should have high atomization efficiency, low noise, and stable flame to ensure high absorption sensitivity and measurement precision.

[0003] A burner uses a premixing device to mix air and fuel in an appropriate ratio to ensure complete combustion. Depending on the classification method, burners can be divided into several types, including oil burners, gas burners, light oil burners, dual-fuel burners, and heavy oil burners.

[0004] Heavy oil burners may experience incomplete combustion. When the carbon in the heavy oil cannot be completely burned, particles will form and adhere to the inner wall of the combustion chamber and the outer wall of the heat exchange tubes inside the combustion chamber. This will affect the heat transfer efficiency of the heat exchange tubes to a certain extent. As a result, more fuel is needed to reach the same temperature. The longer the burner is used, the lower the heat transfer efficiency becomes, and the more fuel is wasted. Utility Model Content
