How Should One Judge the Working State of the Asphalt Mixing Plant’s Combustion System?
Asphalt mixing plants are used to mass-produce asphalt concrete, and their integral components include a variety of subsystems, such as the material input subsystem, the drying subsystem, the combustion subsystem, the powder supply subsystem, and the dust collection subsystem. Each subsystem is an important part of the asphalt mixing plant.
The combustion system of the asphalt mixing plant is an essential subsystem that affects the economy, temperature control precision, and smoke emission of the entire system. This article will briefly introduce how to judge the working state of the asphalt mixing plant’s combustion system.
Generally speaking, it is not practical to conduct accurate and reliable testing of the working state of the combustion system in real operations. Therefore, a relatively simple and effective approach is to observe the flame color, brightness, and shape from a distance. When the combustion system is working properly, the flame of the fuel in the drying should be centered in the center of the dryer, and its surrounding distribution is evenly and does not touch the wall of the dryer. The flame is full and clear, without black smoke trailing. When the combustion system is not working properly, such as with an excessively large flame diameter, serious carbon deposition will occur on the furnace top, which will affect the working state of the combustion system afterward.
In addition, it is also possible to observe the wind door opening of the burner. If the wind door opening is not adjusted properly, it will cause too much or too little air to enter the burner, which will affect the flame’s normal combustion. The normal wind door opening should be able to adjust the airflow to the burner, and not affect the flame’s color and shape, with the flame being blue and with a height of approximately 30-50mm and no smoke and no visible fire.
Therefore, it can be concluded that the working state of the asphalt mixing plant’s combustion system can be judged by observing the flame color, brightness, and shape from a distance. This method is simple and effective and can be used to quickly and accurately detect the working state of the system.
