ELECTRICITY FROM BIOMASS
Many types of biological material can be used in generating electricity. These biomass materials can be waste or by-products or other processes or craps grown for use in biomass plants.
How It Works
Wood waste or biomass from another source is burned to heat water in a boiler. The resulting steam drives a turbine which generates electricity.
When biomass is burned, some of the heat produced can be used to gassify the material. It can then be used in a gas turbine generator, which is much more efficient than a conventional boiler.
Biomass plants are best located near their source of fuel - which usually means in agricultural areas. Common sources of biomass include waste wood from timber mills, crop waste such as corn stalks and rice husks. and the waste from sugarcane processing, called bagasse.
Biomass plants produce carbon dioxide when they burn their fuel. However, the same amount of carbon dioxide is absorbed when the biological material grows. As a result, producing electricity from biomass is carbon neutral.
