Abstract:
     In solar oil pool, asphalt is heated directly by solar energy and heated asphalt flows into high- temperature asphalt tank in lower position. In the closed water circulation system comprising heater, safety valve, high temperature asphalt tank, filter and circular pump, the heater heats water to produce medium-pressure water, which flows through pipeline to further heat asphalt to operation temperature. The present invention can save power and prevent fire.
