Abstract
A fluidized bed unit in which a grate is disposed in a housing to divide the housing into an upper chamber and a lower chamber. A bed of particulate material including fuel is supported by the grate and extends in the upper chamber. The lower chamber has an inlet for receiving pressurized air for passing through the lower chamber, the grate, and the bed of particulate material to fluidize the particulate material. An electrical heating unit is provided for preheating the air as it passes through the lower chamber to ignite the fuel material during startup.
