Abstract
An individual cell of a fluidized bed includes a static bed disposed immediately below the fluidization region. The static bed contains heavy ores or other suitable dense material that can be heated to a temperature above the ignition temperature of the fuel used in the fluid bed. Should the fluidized-bed temperature fall below the ignition temperature of the fuel, the lower thermal conductivity of the static bed permits it to maintain the ignition temperature and to ignite the fuel until the fluidized bed has been rekindled.
