May 10 2013 · Pulverized 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
Pulverized Coal Injection PCI System for Blast Furnaces In the past reactions within the blast furnace were stimulated by injecting heavy oil as auxiliary fuel along with the blasts and oxygen The heavy oil was replaced by pulverized coal after the oil crisis This made it possible to use cheap coal such as noncoking coal
Oct 04 2018 · Injection of pulverized coal in the blast furnace BF was initially driven by high oil prices but now the use of pulverized coal injection PCI has become a standard practice in the operation of a BF since it satisfy the requirement of reducing raw material costs pollution and also satisfy the need to extend the life of ageing coke ovens
Pulverised coal injection PCI is a well established technology It is practised in most if not all countries with cokebased BFs and new BFs are nearly always fitted with PCI capability Waste plastics injection WPI is less Injection of coal and waste plastics in blast furnaces 5 commonly carried out with only a few ironmaking plants in
In the BFGCI process granular coal is injected into the blast furnace as a fuel supplement The coal along with heated air is blown into the lower part of the blast furnace through passages called tuyeres The injected coal reduces the requirement for coke the primary blast furnace fuel and reductant BFGCI technology has the poten
Provides higher coal injection rates compared with oil or natural gas thereby resulting in higher coke replacement rates for given blast conditions Improves furnace productivity and fuel rate In comparison to other injectants coal injection allows utilisation of higher blast temperatures Coal allows higher rates of oxygen to be used to increase productivity Coal injection results in smoother blast furnace operation
The injection of pulverized coal into blast furnaces in Japan began at Nippon Steel Corp’s Oita No 1 blast furnace in 1981 Although the main reducing material in blast furnaces is coke blast furnace operators during and after the 1960s utilized heavy oil as a companion fuel injecting
