- Description
- To accompany the introduction and subsequent optimisation of pulverised coal injection on BlueScope Steel’s Port Kembla blast furnaces, the combustion performance of an extensive range of contender coals was measured in a pilot scale combustion test rig providing a scaled physico-chemical simulation of the combustion of pulverised coal in blast furnace tuyere injection. In tests with air-cooled coaxial lance injection, combustion performance increased with increasing coal volatile matter and further, for each coal, showed a weak increase with increasing test O/C ratio (decreasing coal injection rate). In tests with medium to high inertinite content coals drawn from the Permian geological system of Eastern Australia, combustion performance was generally higher for the coals of the higher inertinite content. For these coals, significant fusibility of the inertinite component was demonstrated.
