Practicing Sustainability at Asphalt Plants | Mix

Jan 28, 2020 · Asphalt plant exhaust gas temperature is typically around 250 degrees F but, with 5% moisture in the incoming materials, dew point is about 160 F, almost a hundred degrees lower. By reducing the exhaust gas temperature to say 170 F, that temperature gap is reduced to 10 F. That change results in a fuel purchase reduction of about 6% and a
