Asphalt Saturation of Roofing Felt on the Felt Machine. Final Report. Progress Report, January 1980-July 1981

摘要

The asphalt roofing industry manufactures approximately 10 million tons of product annually. This requires an estimated 40 trillion Btu's in process heat and 4 million tons of asphalt having a fuel value of 140 trillion Btu's. Pilot equipment was installed on a commercial felt machine to determine whether saturation on the felt machine was feasible and whether energy savings would result. A process was demonstrated by which adequate saturation levels can be achieved. Energy savings are estimated at 6.3 trillion Btu's per year on an industry-wide basis. An economic study with consideration of the rapid industry conversion from organic felt to the less energy-intensive glass mat-based roofing precluded further process scale-up and plans for commercialization.
