Applicable scene

The main function of industrial burners is to mix liquid or gas fuel with air and spray it into the combustion chamber or burner to produce the flame or heat energy needed for combustion. Its application range is very wide:

Industrial heating field: often used in heating furnaces and boilers to provide heat energy for various processes, such as melting metals, processing plastics, producing glass, etc. In the steel industry, burners can provide necessary heat for the heating process of iron and steel production.

Specific industrial furnaces: In certain industrial furnaces with strict requirements for uniform temperature, such as large heat treatment furnaces and die forging heating furnaces, high-speed burners can ensure uniform temperature and prevent localized overheating of workpieces. The high-speed gas flow from the high-speed burner promotes intense circulation of furnace gases, enhancing convective heat transfer within the furnace.

Waste gas treatment: In the thermal destruction method of VOC waste gas treatment, the burner can be used to directly and assist in the combustion of organic gases (VOC), or suitable catalysts can be used to accelerate the combustion of VOC.

Control the ratio of fuel to air

Reasonable regulation of the mixture ratio of fuel and air is the key to ensure the combustion efficiency and stability of the burner. For example, the continuous control pipeline system of air-fuel ratio is mainly used in various industrial kilns, combustion furnaces and other equipment, by adjusting the amount of air to change the combustion effect, so that the combustion reaches the ideal state.

Burner head position selection

The requirements for the length of the burner tube vary depending on the type of burner head. For example, for R and K type burner heads, the length of the burner tube is S1 = S2 + 15mm; for H type burner heads, the length of the burner tube is S1 = S2 + 65mm. Additionally, AIO series burners require burner bricks.

Safety precautions

Prevent detonation

During the ignition process of industrial furnace burners, detonation sometimes occurs. Although it generally does not cause significant economic losses, it poses potential hazards. Burner designers should thoroughly understand the causes of detonation and take preventive measures. Detonation can be divided into thermal detonation and chain-chain detonation. The former mainly relies on the continuous accumulation of heat to self-heat up, eventually reaching a rapid reaction rate; the latter primarily depends on chain branching to continuously accumulate activated molecules, ultimately achieving a rapid reaction rate and releasing heat.

Regular maintenance and inspection

The burner should be maintained and checked regularly, including checking whether the components of the burner are in good condition, whether the combustion state is normal, and whether the pipe connection is tight. For regenerative burners, special attention should be paid to the state of the regenerative ball; for burners equipped with burner bricks, check whether the burner bricks are damaged.
