The Pulverized Coal Injection (PCI) System is a system to inject pulverized coal into a blast furnace continuously with high precision. The PCI was developed by Denka Consultant Engineering Co., Ltd. (DCE) based on the technology used for the High Flow Pneuma .

Use of pulverized coal as a supplementary fuel in ironmaking blast furnaces is of great importance for global requirements such as energy saving and environmental,2) In the early 1980th, the pulverized coal injection (PCI) rates were only 50–60 kg/tp (kg per ton of pigiron produced) and then went up to 150–200 kg/–7 ...

14/12/2007 · A threedimensional multiphase CFD model using an Eulerian approach is developed to simulate the process of pulverized coal injection into a blast furnace. The model provides the detailed fields of fluid flow velocity, temperatures, and compositions, as well as coal mass distributions during the devolatilization and combustion of the coal.

10/11/2000 · Advanced Pulverized Coal Injection Technology and Blast Furnace Operation. In order to reduce the cost of running blast furnaces (BFs), injected pulverized coal is used rather than coke to fire BFs. As a result of this, unburned fine materials are blown with the gas into the bosh and dead man areas with possible detrimental effects on gas flow ...

The actual combustion rate of pulverized coal in the blast furnace tuyere is hard to be measured. In this research, the combustion rate of pulverized coal injected into oxygen blast furnace was obtained by a new equipment. This equipment can simulate the actual blast furnace well, and the relationship between pulverized coal injection (PCI) ratio and A O/C was established by mathematical ...
