ASPHALT HEATERS LOWER COSTS, IMPROVE EFFICIENCY

Asphalt heating and storage equipment is described, the use of which reduced heating costs by 10 percent and saved $10,000 in installation costs. The system includes two 30,000-gal asphalt storage tanks, one of which is equipped with a Trailburner and the other with a Bulktherm aspahlt heater. The latter is concerned solely with heating the asphalt and holding it at a uniform temperature. The Trailburner also provides auxiliary heating to the tower, trace pipes and auxiliary equipment, holding the asphalt in the system at the same temperature as in the tanks (approximately 300 to 325 F plus or minus 1 deg). Each combustion chamber includes a tangential air inlet and a cloverleaf baffle which allow only hot gases to get through and no flame comes in contact with the combustion tube. There is also an arrangement which prevents any visible emission coming from the stacks. The 80 to 85 gal. of oil used in this equipment never exceeds the temperature of asphalt and cannot break down from overheating. High temperature mechanical seals in the hot oil pump eliminate leakage ordinarily associated with boiler rooms and centrifugal pumps. Another advantage of this equipment is its ability to unload tank trucks more rapidly. The use of internally traced piping ensures fast efficient heating. A useful feature of the installation described here, is a liquid level indicator.
