What are the Operating Requirements for a Heavy Oil Asphalt Mixing Station Burner?
Generally, asphalt mixing stations have dedicated burners, but the fuel used is the same as that of ordinary burners. So, what should be done when using a heavy oil burner in an asphalt mixing station? Let’s take a look at the operating requirements for a heavy oil asphalt mixing station burner.
The operating requirements for a heavy oil asphalt mixing station burner:
The fuel used in a heavy oil asphalt mixing station burner is heavy oil, which is a liquid fuel and can be classified into light oil and heavy oil based on the viscosity rating. Even if light oil is not heated, it can have a good atomization effect. Before using heavy oil or residual oil, it must be heated to ensure that the viscosity of the oil is within the range allowed by the burner. The use of viscosity meters and finding the best fuel, heating temperature, and residual oil samples should be submitted to the laboratory for testing their thermal value.
If our asphalt mixing station uses a heavy oil burner, we should check and adjust the burner after using heavy oil or residual oil for a period of time. We can use a gas analyzer to determine whether the fuel is fully burned, and check the drying drum and bag filter to see if there are oil mist or odors to avoid causing fires and oil料堵塞. The accumulation of oil on the mist spray nozzle will increase as oil quality deterioration, so cleaning it regularly is necessary.
When using residual oil, the position of the outlet of the storage tank should be higher than the bottom by about 50cm to prevent water and debris deposited at the bottom of the tank from entering the fuel pipelines. Before feeding the fuel to the burner, the filters used must be filtered through a 40-mesh mesh size. The pressure gauges on both sides of the filter ensure that the filter is working properly. When blocked, it can be detected and cleared in a timely manner.
So, these are all the operating requirements for a heavy oil asphalt mixing station burner. In addition, after work is completed, it is necessary to first turn off the burner switch before carrying out the heating of heavy oil, and if there is prolonged downtime or in cold weather, switching of oil circuit valves to light oil should be carried out. Clean the oil path, otherwise, it may lead to non-smooth or difficult ignition of the fuel path.
