Title: Improvements in or relating to electric heating
IPC: H05B3/00
Filed: 1957-04-02
Abstract: A bed of conductive solid particles is fluidised or held in suspension in a gas and heated by the passage of electric current, and a solid medium reacting endothermically with the bed is passed into it.  In one example the bed is granulated carbon of particle size below 0.5 mm. and fine particles of lime or chalk are fed continuously on to the bed.  Molten calcium carbide forms at the bottom and the carbon monoxide released serves to fluidise the bed. The heating current may be introduced by water-cooled electrodes or by induction.  The processes may be carried out at pressures above or below atmospheric.ALSO:A bed of conductive sold particles is fluidized or held in suspension in a gas and heated by the passage of electric current, and a solid medium reacting endothermically with the bed is passed into it.  In one form particles of alumina below 0.5 mm. are thus heated to 1800 DEG C. and carbon is sprinkled on to reduce the alumina to aluminium which collects at the bottom.  The carbon monoxide generated fluidizes the bed.  As the cold conductivity of the alumina is low the bed may be started as a layer of carbon which is replaced by alumina as the bed heats up.  The heating current may be introduced by water-cooled electrodes or by induction.  The processes may be carried out at pressure below atmospheric.
