Heating bitumen for most of the final uses is a critical stage. Generally, the most important aspect in this procedure is heat control. Temperature and heat control can affect various properties of the product, including its quality. The safe and recommended maximum temperature is 230℃.
Oxidized bitumen is not hazardous below 100℃ during shipping operations. Heating and heat transfer should be controlled. Inappropriate heat transfer may cause overheating and release low flash vapors and these unwanted side products cause a higher fire risk.
Also, melted bitumen should not be left in the boiler to cool down. Because this can cause overheating and needs more positional energy. Furthermore, placement and installing of any temperature and pressure monitoring and control devices is very important. Because if their placement is not right, thermometers can’t display the actual temperature, which can lead to poor monitoring and thermal conductivity.
