Southeastern Regional Biomass Energy Program: The Pressure Steam Drying of Hardwood Biomass for Fuel. Annual Report, August 1, 1984-August 1, 1985

摘要

In recent years the ingrowth of ''undesirable'' hardwoods in the South has been increasing, providing the opportunity for southern forest products industries to convert from fossil to wood fuel. Although the drying of wood chips prior to burning increases burner efficiency, increases the available heat, and reduces particulate emissions, the high energy consumption in commercial dryers (which vent hot, humid air to the atmosphere) makes the process economically unattractive. A different approach would be to dry hardwood chips in a pressurized system which would generate recoverable steam energy, which could result in drying cost reductions. This project evaluates the use of pressure steam drying to dry hardwood chips which may lead to an economical drying process. 1 fig., 2 tabs. (ERA citation 11:022276)
