Grindability of biocarbon and coal blends in rolling mill
2020年4月19日 ABSTRACT Partial substitution of pulverized coal (PCI) by renewable biocarbon for blast furnace injection is a practical approach to reduce GHGs in the steel production sector For using biocarbon as feedstock, it is critical to measure its grindability to understand its milling behavior compared to that of typical PCI coal, and thus help decide on adjusting grinding Today in Asia, coal injection equipment is installed on all BFs in Japan, Korea and Taiwan and nearly all of the full sized furnaces in China A goal was set for an injection rate of 150 kg/thm to be achieved in all of China’s large and medium BFs in 2005, and an average 100 kg/thm in the smaller ones (Pei, 2003) Coal injection is installed Use of PCI in blast furnaces ICSCPulverized Coal Injection (PCI) using the denseflow method The Küttner developed and perfected denseflow method offers several advantages over a lowerdensity system Higher injection rates are achieved with simultaneously lower coke rates, which can optimize the fuel costs of the blast furnacePulverized coal injection (PCI) Iron Steel Kuettner GroupOur ATOX® Coal Mill is a compact vertical roller mill that can grind almost any type of raw coal The coal mill utilises compression and shear force generated between the large rollers and the rotating table to crush and grind raw coal, removing the need for a separate piece of equipment for crushing The coal mill can also grind petroleum ATOX® Coal Mill FLSmidth Cement
