The choice of burner needs to consider multiple factors to ensure combustion efficiency, safety and environmental impact. There are two main differences between these two burners:

1. Fuel type: The two fuels are different

Fuel burner: liquid fuel is used, such as heavy oil, diesel, etc.

Gas burner: it uses gas fuel, such as natural gas, town gas, liquefied gas and so on.

2. Structure and characteristics

Fuel Burner: To atomize liquid fuel, various atomization methods are used, which influence the design of the burner. For example, gas medium atomizing burners use the momentum of the gas to atomize the fuel; oil pressure burners atomize the fuel by allowing it to flow out under high pressure; rotary cup burners atomize the fuel by spraying it as a thin film through a high-speed rotating cup and then atomizing it with air. Depending on the method of regulation or control, the type of fuel used, the shape of the flame formed, and the temperature of the combustion air, burners can be classified and have distinct features.

Gas burner: Taking the natural gas burner as an example, it is typically produced using a modular design, which makes it simple in structure and easy to maintain and operate. Inside the burner, air and gas are initially mixed, ensuring complete combustion of the gas, stable flame, and preventing flashback or blowout. The main components include the burner housing, combustion tube, gas cap, air swirl plate, ignition electrode, detection electrode, and fire viewing mirror.

3. Application

Fuel burner: Used in scenarios with specific considerations for fuel sources and costs, such as in coke oven drying. In the early stages of drying, when heat demand is low, oil can be easily controlled; later, when fuel consumption increases, compressed air is used for atomization. However, due to its limitations, its usage has gradually decreased in modern large-scale industrial applications.

Gas Burners: With the widespread availability of natural gas and other gas resources, their applications have become increasingly diverse. For instance, natural gas burners are widely used in industrial kilns and chemical heating systems. In coke oven drying, natural gas burners are preferred for their precise temperature control, high safety, ease of management, and lower costs, making them the go-to choice for new coke plants. Gas burners are also utilized where gas resources are available.

4. Carbon accumulation

Fuel burner: It is relatively easy to produce carbon deposits during combustion, which requires more frequent cleaning and maintenance.

Gas burner: take the natural gas burner as an example, there is almost no carbon accumulation; but the gas burner is more likely to produce carbon accumulation.

To sum up, there are obvious differences between fuel burners and gas burners in terms of fuel type, working principle and application scenarios. Users should consider the actual needs and site conditions when choosing.
