Solar energy heating of asphalt to 200 F in storage tanks - final report

Abstract

A high-temperature (185 - 225°F) asphalt storage system has been designed and constructed at Perry, Oklahoma. This report documents the design process, construction procedures, and evaluates data gathered to date. The design is covered in detail including sizing the auxiliary heater, estimating heat losses, sizing collectors, ancl designing controls. The construction stage is documented including air bleed system problems, collector protection, and start-up procedures. Data gathered for a fifteen day period in December, 1979 is compared directly to the computer model used to design the solar system. Asphalt temperatures are also recorded for the period from Dec. 1, 1979 to Jan. 15, 1980.
