The influence of asphalt mixing plant cannot be underestimated. It also has a great impact on the heating efficiency of asphalt pipeline. This is because the important performance indicators of asphalt, such as viscosity and sulfur content, are closely related to asphalt mixing station. Generally speaking, the greater the viscosity, the worse the atomization effect, which directly affects the work efficiency and fuel consumption. As the temperature rises, the viscosity of heavy oil gradually decreases, so high-viscosity oil must be heated for smooth transportation and atomization.

Therefore, in addition to understanding its conventional indicators, it is also necessary to master its viscosity-temperature curve when selecting it to ensure that the heating can make the asphalt reach the viscosity required by the burner before atomization. When checking the asphalt circulation system, it was found that the temperature of the asphalt pipeline did not meet the requirements, causing the asphalt in the pipeline to solidify.
The main reasons are as follows:
1. The high-level oil tank of the thermal oil is too low, resulting in poor circulation of the thermal oil;
2. The inner tube of the double-layer tube is eccentric
3. The thermal oil pipeline is too long;
4. The thermal oil pipeline has not taken proper insulation measures, etc. These are the main factors affecting the heating effect.
