Abstract: Goals were to demonstrate feasibility of using the geothermal waste effluent from the HGP-A well as a heat source for a kiln operation to dry hardwoods, develop drying schedules, and develop automatic systems to monitor/control the geothermally heated lumber dry kiln systems. The feasibility was demonstrated. Lumber was dried in periods of 2 to 6 weeks in the kiln, compared to 18 months air drying and 6--8 weeks using a dehumidified chamber. Larger, plate-type heat exchangers between the primary fluid and water circulation systems may enable the kiln to reach the planned temperatures (180--185 F). However, the King Koa partnership cannot any longer pursue the concept of geothermal lumber kilns.
Description: Report Number: DOE/SF/15798--T9
Sponsor: DOE Contract Number FG03-85SF15798. "This is a report of work performed for the Community Geothermal Technology Program, a small grant program administered jointly by the Hawai'i Natural Energy Institute and the State of Hawai'i Department of Business, Economic Development and Tourism. This project was one of five funded under the second phase of the program, which were awarded in 1988. Funds for this phase were provided by the U.S. Department of Energy, the County of Hawai'i, and donations from private business."
