The asphalt mixing plant is an important piece of equipment. Due to the complexity of its structure, some problems may occur during use. For example, the problems that often occur in its heavy oil combustion system include: the burner cannot start, the burner cannot ignite normally, and the flame Accidentally extinguished, etc. So, how to deal with these problems?

This situation is also a relatively common one. There are many reasons. Therefore, when the burner of the heavy oil combustion system of the asphalt mixing station cannot be started, this problem should be investigated first. The specific sequence is as follows: Check whether the main power switch is normal and whether the fuse is blown; check whether the circuit interlock is open and whether the control panel and thermal relay are normal. If the above is found to be in a closed state, they should be opened in time; check that the servo motor should be in the low flame position, otherwise the adjustment Set the switch to "auto" or adjust the potentiometer to small; check whether the air pressure switch can work normally.
In the second case, the burner cannot ignite normally. For this phenomenon, based on our experience, we can determine that the possible causes are: the flame detector mirror is stained with dust or damaged. If the mirror of the heavy oil combustion system of the asphalt mixing station is stained with dust, clean it in time; if the detector is damaged, new accessories should be replaced. If the problem persists, adjust the detector's detection direction to fix it.
Then, the fourth situation is that the system's burner flame goes out unexpectedly. For this kind of problem, if the inspection finds that it is caused by dust accumulation in the nozzle, then it can be cleaned in time. This situation may also be caused by excessive or insufficient dry combustion air. Then, we can adjust the blower damper of the heavy oil combustion system of the asphalt mixing station to control it. In addition, you should also check whether the heavy oil temperature is qualified and whether the heavy oil pressure is up to standard. If it is found that it cannot ignite after extinguishing, it may also be due to excessive combustion air. At this time, you can carefully check the piston rod air-oil ratio, cam, connecting rod mechanism, etc.
For the above possible problems, when we encounter them at work, we can adopt the above methods to deal with them to ensure the normality of the heavy oil combustion system and the stable operation of the asphalt mixing plant.
