In the construction of asphalt pavement, the mixing and heating of asphalt materials is an important part. Its operating cost accounts for an important share of the entire production and operation cost. The fuel cost is large, and it can easily reach hundreds of millions of yuan. The traditional asphalt mixing plant that uses heavy oil as fuel produces large pollution after combustion, and the combustion is incomplete and the quality is unstable. The use of clean pulverized coal as fuel has many advantages: low production cost, convenient ignition method, full combustion, safe and energy-saving, green and environmentally friendly, non-corrosive, no harm to equipment, safe and pollution-free storage, good stability, and is particularly suitable for industrial continuous production.
