Benefits Assessment of the GRI Venting/Flue Gas Management Project for Mid-Efficiency Fan-Assisted Furnaces. Topical Report, July 1990-December 1991

摘要

The report presents a traditional cost-benefit analysis of the economic impactsof premature corrosion in mid-efficiency fan-assisted furnace systems. The purpose is to assess the benefits of the solution developed in the GRI Venting/Flue Gas Management Project. Information developed in the project is expected to eliminate corrosion problems resulting from improper vent sizing. In the report, the net present value of repair costs due to premature corrosion is estimated for mid-efficiency fan-assisted furnace systems installed from 1980 to 2000 under three scenarios: (1) no venting guidelines, (2) industry-sponsored venting guidelines (available in 1996), and (3) GRI venting guidelines (available in 1991). Benefits are defined as the difference between projected repair costs in scenarios (2) and (3). The cost-benefit analysis results show that the incremental benefits of the GRI project, in 1990 dollars, are approximately $700 million.
