Understanding Pulverized Coal Injection in Blast

Fig 1 Pulverized coal combustion and gas composition in raceway. The extent of combustion (combustion efficiency), and hence the amount of unburnt material transported out of the raceway, depends on several parameters which include (i) properties of the coal, such as the VM content, particle size and density, and (ii) operating conditions, for example, blast gas composition and temperature

Steel mills restarting 34% of blast furnace capacity

The restarts represent around 34% of the total blast furnace capacity that was hot-idled or temporarily halted due to COVID-19, and the rest can be expected to restart by year-end, according to the report. "This is not a surprise, given the time-constraints of hot idling and as demand is picking up," said analysts led by Myles Allsop.
