What are the operating requirements for the burner of the heavy oil asphalt mixing plant?
Asphalt mixing plants generally have dedicated burners, but the fuel burned is the same as ordinary burners. So, what should be done when using a heavy oil burner in an asphalt mixing plant? Let's take a look at the operational requirements for the burner of the heavy oil asphalt mixing plant.
Operating requirements for the burner of the heavy oil asphalt mixing plant:
The fuel used for the burner of the asphalt mixing plant is heavy oil, which is a liquid fuel divided into light oil and heavy oil according to different viscosity levels. Light oil can have a relatively good atomization effect even without the need for heating. Before using heavy or residual oil, the oil must be heated to ensure that its viscosity is within the allowable range of the burner. Using a viscometer to measure the results and find the optimal fuel, heating temperature, and residual oil samples should be sent to the laboratory in advance for calorific value testing.
If our asphalt mixing plant uses a heavy oil burner, please check and adjust the burner after using heavy oil or residual oil for a period of time. A combustion gas analyzer can be used to determine whether the fuel is fully burned, while checking the drying drum and bag filter to see if there is oil mist or odor, in order to avoid fire and oil blockage. The accumulation of oil on the atomizer will increase with the deterioration of the oil quality, so it is necessary to clean it regularly.
When using residual oil, the oil outlet of the storage tank should be located about 50cm above the bottom to prevent water and debris from depositing at the bottom of the tank from entering the fuel pipeline. Before the fuel enters the burner, it must be filtered using a 40 mesh filter. Oil pressure gauges are installed on both sides of the filter to ensure its normal operation. When blocked, it can be detected and cleaned in a timely manner.
The above is all the requirements for the operation of the burner in the heavy oil asphalt mixing plant. In addition, after the work is completed, the burner switch should be turned off first, and then heavy oil heating should be carried out. In case of prolonged shutdown or cold weather, the oil circuit valve should be switched to light oil. Clean the oil circuit, otherwise it may cause blockage or difficulty in ignition.
