WTE: Fluidized Bed Technology
Oxidation of combustible materials at elevated temperatures.
- Fluidized bed
Intensively mixed bed of solid particles by means of an upward gas flow through the bed that keeps the particles in motion, somewhat like bubbling of gas through a liquid bath.
Definition of the Subject and Its Importance
Natural resources are often simply differentiated in “renewable” (i.e., plant and animal life) and “nonrenewable” (i.e., minerals and fossil fuels). Efficient use of both renewable and nonrenewable resources is vital for sustainability and the future quality of life on earth. Energy recovery from used materials, also called waste-to-energy, is complementary to material recovery (i.e., recycling). Currently, about 90% of all presently consumed fossil fuels go directly to combustion and the generation of electricity or mechanical energy. The rest is used to produce plastics and other synthetic materials.
There are two major combustion technologies for recovering energy from...
