Wood Char in Sintermaking

Biomass utilization practices for iron and steelmaking are being developed to replace coke breeze in the sintering process. Wood char has been shown to be a suitable replacement for coke breeze in the sintering process, resulting in process improvements and reduction of acid gas levels in process emissions.  A fuel blend of 20% charcoal and 80% coke breeze was also found to increase the sinter plant productivity by 8%.

Wood Char in SintermakingCosts & Benefits

Parent Process: Sinter Plant
Energy Savings Potential

A substitution of around 20% of coke breeze with charcoal in sintering plants is technically feasible.
CO2 Emission Reduction Potential

Charcoal is Greenhouse neutral i.e. CO2 liberated in the sintering process is absorbed By the next crop of growing trees.

 
Costs

Cost of Charcoal production is being reduced by using "Cheaper Cuts" i.e. the leaves and the twigs of Malle Trees.
