Gasifiers in Industry Program, University of Minnesota - Duluth Campus Gasifier Project. Final Report, October 1976-August 1982

摘要

The University of Minnesota installed and operated a three ton/h low Btu coal gasifier for the generation of boiler fuels at the Duluth Campus with partial funds provided by a Cooperative Agreement with the United States Department of Energy, Gasifiers in Industry Program. The primary objective of the project, that started in 1976 and ended in 1982, was to evaluate the technical and economic aspects of the operation of a state-of-the-art low Btu coal gasifier in an actual operating environment. The gasifier was run intermittently for 10,500 h during 11 runs using western United States sub-bituminous coals. The thermal efficiency of the gasifier was found to average 90% during performance tests. The estimated cost of generating the gas and by-product tar fuels to meet University fuel requirements, excluding plant investment costs, was $7.09/million Btu with a Wyoming sub-bituminous coal. 16 references, 13 figures, 8 tables.
