Saving Energy at Your Hot-Mix Plant
This article describes how hot-mix asphalt plant owners may decrease their operating costs by making operations more efficient. By sloping the surface beneath aggregate stockpile, excess moisture is drained away without having to evaporate it by heating, which, the author notes, could potentially save a plant owner $180,000 per year for a 200,000 ton per year plant. By insulating burner fuel lines and preheating burner fuel, one might save $70,000 for the same sized plant. Adding 10 percent more recycled asphalt pavement is projected to save $400,000 per year in a hypothetical plant, while switching to coal would save $320,320 per year. Lastly, the author suggests the addition of a variable frequency drive to exhaust fans and burner blowers, which may save $60,000. The end result, it is noted, will come to $5.15/ton, or over $1,000,000 for the hypothetical hot-mix plant.
