USE OF RECUPERATIVE HEATING FOR START-UP OF ELECTROLYTIC CELLS WITH INERT ANODES

摘要

The present invention is directed to methods for preheating a molten salt electrolysis cell having inert anodes (24) using recuperative gas heating by combusting a first gas outside the cell chamber (20) in a combustion chamber (2) and using to heat a second gas in recuperator (8) which second gas us passed to the cell chamber (20). The inert anode can be a cermet inert anode.
