Coal based power generation. The energy conversion efficiency of the coalbased power generation process is represented by the following formula: (8) η U 1 = P G × ( 1 − A P R) / C C P × 100 % where PG is Power generation of coal (tce), APR is auxiliary power ratio (%), and CCP is coal Consumption for power (tce).

Pulverised coal injection (PCI) is used in ironmaking to replace expensive and energy intensive coke with coal, reducing overall costs and greenhouse gas emissions. As the coke making process removes some of the sulphur present in coal, the utilisation of PCI results in the admission of greater levels of sulphur into the blast furnace.
