An in-situ oxygen probe was used to determine the corrosion potential (oxygen partial pressure) of the in-bed environment inside two fluidized-bed coal combustors with similar internal configurations. Both FBC's contained potentially dangerous corrosive environments in the bottom of the bed, near the coal feed nozzles, and along the walls. Several design modifications were implemented in an attempt to reduce the occurrence and severity of these environments and their effectiveness is discussed.
