WhatsApp: +86 18203695377Pulverized coal injection (PCI) is a process which involves injecting large volumes of fine coal particles into the raceway of the blast furnace (BF). Pulverized coal is an important auxiliary fuel used in the BF ironmaking. PCI provides auxiliary fuel for partial coke replacement and has proven both economically and environmentally favourable.
WhatsApp: +86 18203695377Coal is primarily used as fuel to generate electric power in the United States. In coalfired power plants, bituminous coal, subbituminous coal, or lignite is burned. The heat produced by the combustion of the coal is used to convert water into highpressure steam, which drives a turbine, which produces electricity. In 2019, about 23 percent of all electricity in the United States was ...
