Main drivers influencing development: Ore

• Mineralogy is changing (easily mined ores exhausted)

Reductants• Availability vs cost

Power• Limitations imposed• Cost

Environmental• Effluent• Water usage

Recent technology developments by Tenova Pyromet:

Tenova Pyromet

Dry Gas Scrubber

Multiple Pre-Heater

Gas suspension Pre-Heater

High efficiency gas cleaning

Reduce Power Consumption

Reduce Power Consumption


8

Advantages:

Allows the use of lower quality

reductants

Uses less water than venturi

scrubbing

Manage tar issues in the gas

Energy recovery through combustion

of waste gas

Tenova Pyromet

Dry Scrubber


9

Reduces power consumption by pre-heating feed

materials

Can be retrofitted to some existing furnaces

Reduces furnace building height and subsequent

overall plant footprint

Effectively utilise energy contained in furnace off-

gas

Best suited to furnaces with

agglomerated feed

Tenova Pyromet

Multiple Pre-Heater


10

Reduces furnace power consumption

Higher feed temperature achievable

Proven technology, new application

Suited to furnaces using fine feed materials

(typically DC furnaces)
