The PCI method is based on the simple concept of primary air (termed the "conveying gas") carrying pulverized coal which injected through a lance to the tuyere (mid-bottom inlet of a blast furnace), then mixed with secondary hot air (termed the "blast") supplied through a blowpipe in the tuyere and then piped to a furnace to create a balloon ...
Metallurgical coal or coking coal [1] is a grade of coal that can be used to produce good-quality coke. Coke is an essential fuel and reactant in the blast furnace process for primary steelmaking. [2] [3] [4] The demand for metallurgical coal is highly coupled to the demand for steel. Primary steelmaking companies often have a division that ...
The mine plans to increase its annual saleable PCI and coking coal production to three million tonnes (3.3 million tons) as port constraints are eased at Dalrymple Bay Coal Terminal. Millennium provides a low-ash coking coal and low-to-mid-volatile PCI coal to customers in Japan, Korea and India.
The Middlemount Coal Mine is an open-cut mine located approximately 90 kilometres north-east of Emerald and some 7 kilometres west of the township of Middlemount in Queensland's Bowen Basin. The mine produces medium-volatile pulverized coal injection (PCI) coal and semi-hard coking coal for the export market. Full scale operations at the open ...
As of 2020, coking coal in the U.S. sold for about $127/short ton, compared with $50.05/short ton for bituminous coal generally. The cost of coking coal is about 3.5 times as high as the cost of coal used for electrical power (which includes lower ranks of coal, such sub-bituminous coal and lignite, as well as noncoking bituminous coal.)
