This report shares lessons learnt in the second quarter of the project, including observations on the capacity of biochar to hold moisture, the importance of particle size distribution and the flow parameters of biochar/coal blends compared to coal alone.
Report extract
At the end of the second quarter of the project, three significant lessons have been identified:
- Biochar has significant capacity to hold moisture,affecting transport efficiency and handling procedures.
- Achieving the target particle size distribution during grinding of biochar will be more difficult than for coal alone and will require changes to the operation of BlueScope’s Pulverized Coal Injection(PCI) Plant.
- Pulverized biochar/coal blends show improved flow parameters compared to coal alone.
