Since the asphalt mixing equipment used was purchased relatively early, its combustion and drying system can only meet the requirements for diesel combustion. However, as the price of diesel increases, the economic efficiency of using the equipment becomes lower and lower. In this regard, users hope that it can be solved by modifying the combustion system of asphalt mixing equipment. What reasonable solutions do experts have for this?

The transformation of the combustion system of asphalt mixing equipment mainly includes the following aspects. The first is the replacement of the combustion device, replacing the original diesel combustion spray gun with a heavy-duty and diesel dual-purpose spray gun. This device is relatively short and does not require winding of electric heating wires. The key is that it will not be blocked by residual heavy oil, allowing the heavy oil to be fully burned and reducing the consumption of heavy oil.
The second step is to modify the previous diesel tank and lay a thermal oil coil at the bottom of the tank so that it can be used to heat the heavy oil to the required temperature. At the same time, a separate electric control cabinet must be set up for the entire system to realize automatic switching between diesel and heavy oil, and to protect the system with audible and visual alarms.
Another part is the improvement of the thermal oil furnace, because the thermal oil furnace that burned diesel was originally used. This time, it was replaced with a coal-fired thermal oil furnace, which can greatly save costs.
