Asphalt mixing plant is a complete set of equipment for batch production of asphalt concrete. The complete machine composition of the equipment includes various systems
systems, such as batching system, drying system, combustion system, powder supply system and dust prevention system. Each system is an important part of the asphalt mixing plant.

The working status of the combustion system of the asphalt concrete mixing plant has a great impact on the entire system, which is related to the economical operation of the entire system, temperature control accuracy and flue gas emission indicators. Then, this article briefly introduces how to judge the working conditions of the combustion system of asphalt mixing plant.
Generally speaking, due to the complexity of testing equipment and methods, the working process of most asphalt mixing plants cannot achieve any conditions. Therefore, it is more convenient to judge the working conditions through a series of relatively intuitive factors such as the color, brightness and shape of the flame. This method is very simple and effective.
When the combustion system of the asphalt concrete mixing plant is working, when the fuel is burning normally in the drying cylinder, the user can observe the flame through the front of the cylinder. At this time, the center of the flame should be in the center of the drying cylinder. When it hits the wall of the tube, the flame is full. The outline of the flame is relatively clear and there will be no black smoke tail. Abnormal conditions of the combustion system, such as
The diameter of the flame is too large. In this case, serious carbon deposits will form on the furnace tube, which will affect the subsequent working status of the combustion system.
