Energy Units
This is a short reference of conversion factors used by scientists at Oak Ridge National Laboratory.
- 1 BTU (British Thermal Unit) = 1055 Joules
- 1 kW (Kilowatt) = 3413 BTU/hr = 1.341 horsepower
- 1 kWh (Kilowatt-hour) = 3.6
Drying Woody Biomass
By B. Jackson, R. Schroeder, and S. Ashton
Biomass feedstock moisture content is dependent on post-harvest handling and storage conditions. Moisture may be lost by transpiration drying, through foliage, or from open wood surfaces. The rate of drying depends on …
Dry-matter Loss
By S. Ashton
Dry-matter loss, which is the degradation of lignin, cellulose, and hemicellulose, occurs when wet woody biomass, in any form, is not utilized immediately. The degree to which dry-matter loss occurs, is largely dependent on the materials moisture …
Storing Woody Biomass
S. Ashton, B. Jackson, and R. Schroeder
For the most part, woody biomass for energy is harvested, pre-processed, transported, and utilized all within several days. However, there is still a need for storage capability, for example when demand exceeds supply, …
In-woods Pyrolysis of Woody Biomass
by EL. Taylor and S. Ashton
Advanced Biorefinery’s modular pyrolysis system is designed for use in the forest. The complete system also includes a reactor and a condenser, not shown here.
In areas where the cost of transporting wood remains …
Woody Biomass Properties
Check out how the properties of woody biomass affects how it may be converted into useful forms of energy (solid, liquid, or gaseous fuels) and products (polymers, bio-plastics, char, pellets, and acids) at a biorefinery.Woody biomass is converted into …
