How to Choose a Burner for an Asphalt Mixing Plant?

The asphalt plant burner is a crucial component when choosing an asphalt mixing plant. Its selection will have a direct impact on the performance and efficiency of the mixing plant. This article will address burner selection and determination in detail to help you better understand how to choose the right asphalt plant burner for your project needs.

What Are the Types of Burners for An Asphalt Mixing Plant?

Before choosing a burner, you first need to understand the various types of burners and their characteristics. Common burner types are shown in the following.

• Pulverised coal burner: Suitable for the use of pulverised coal as a fuel for the scene, with high combustion efficiency, the advantages of uniform heat release.
• Oil Burner: Uses oil as fuel, usually used in situations where natural gas or coal cannot be used, and is characterised by easy operation and cleanliness.
• Natural gas burner: Using natural gas as fuel, with good environmental protection and high combustion efficiency, it is a common choice.
• Dual-use oil and gas burners: flexible and adaptable, you can choose to use fuel oil or natural gas as fuel according to the actual needs.

Different types of burners have their own characteristics. It is vital that you choose the most suitable burner for your production needs and environmental conditions.

What Performance Does A Good Asphalt Plant Burner Have?

When choosing an asphalt plant burner, in addition to the type, you also need to consider whether its performance meets the needs of the project. A good burner for the asphalt batch plant should have the following characteristics.

Asphalt Plant Burner Performance Indicators

Burner performance indicators are the key aspects to consider when choosing a burner for asphalt mixing plant. They are directly related to production efficiency and product quality. The following will detail several key indicators of burner performance.

Consideration of Heavy Oil Characteristics

For projects using heavy oil, special consideration should be given to the characteristics of heavy oil to ensure that the burner selected can effectively deal with.

• Atomisation particle size: The atomisation particle size of heavy oils should be controlled to within 15μm to ensure good combustion.
• Temperature control: The asphalt mixing plant burner should have good temperature control ability to maintain a stable combustion temperature and improve production quality.
• Accuracy of oil quantity: The burner must control oil precisely for stable fuel supply, preventing production issues from oil fluctuations.
• Stable calorific value: The calorific value of heavy oil changes greatly. Therefore, the burner should handle calorific value fluctuations to maintain combustion efficiency.

Air Distribution and Environmental Adaptability

In addition to the performance of the fuel and the burner itself, it is also necessary to consider the control accuracy of the air distribution and the adaptability of the burner to the environment.

• Control accuracy of air distribution: During combustion, air distribution control should be within ±1% for thorough mixing of fuel and air.
• Environmental adaptability: The burner must adapt well to varying temperatures and altitudes for normal operation in different conditions.

In Conclusion

Choosing the right burner is critical to the operation of an asphalt mixing plant. Consider fuel type, burner performance, heavy oil characteristics, air distribution, and environmental adaptability when selecting an asphalt mixing plant burner.
