Utilise chemical energy contained in cleaned off gas (CO rich) as an energy source – thereby reducing the electrical energy required by up to 15%
Volatiles are removed from feed blend prior to furnace, thereby improving off gas CO quality
Hot, dried feed results in less electrode movement, improving furnace stability
Increases furnace production
Reduces system heat losses
Multiple units, that allows independent control per unit, reacting to furnace conditions. Multiple units allow for the pre-heater vessels to be located around the electrodes (not above), reducing the furnace building height.
