<p>This relates to electric arc discharge apparatus including at least two pair of electrodes and a single power source which comprises a multi-phase transformer, arc stabilization means and two or more rectifier bridges. Each rectifier bridge provides a pair of electrical power outputs to supply power to a respective pair of electrodes. The invention enables the multi arc system to be employed using a single power source and is of particular use in heating gas to be used in the oxidation of titanium tetrachloride for the production of titanium dioxide pigments.</p> |
