May 10, 2013· Pulverized coal injection in a blast furnace. Pulverized Coal Injection (PCI) is a process that involves injecting large volumes of fine coal particles into the raceway of a blast furnace (BF). This provides not only a supplemental carbon source but also speeds up the production of liquid iron besides reducing the need for metallurgical coke ...
Pulverized coal injection (PCI) into the blast furnace (BF) has been recognized as an effective way to decrease the coke and total energy consumption along with minimization of environmental impacts. However, increasing the amount of coal injected into the BF is currently limited by the lack of knowledge of some issues related to the process.
Pulverized coal injection is a process that involves blowing large volumes of fine coal granules into the BF. The raw material is by washing and removing the vermiculite from coal to form clean coal, which is high quality. Pulverized coal: pulverized is a technology that is a reasonable choice for blast furnace technology advancement.
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.
Pulverized Coal Injection (PCI) coal Used in steelmaking, but it is not indispensable like met coal. It is a softer, noncoking coal which is pulverized and injected into the blast furnace to supply heat, which in return reduces energy use and emissions.
Semisoft coking coal (SSCC) Pulverized coal injection (PCI) coal; ... The process reduces the carbon content by 90% and results in a molten iron known as hot metal. The hot metal is then drained from the blast furnace and sent to the BOF where scrap steel and limestone are added to make new steel.
A proposed upper limit for pulverized coal injection, which would burn completely in the tuyere combustion zone, is estimated at 180 kg/t when the fuel rate is 500 kg/t. An upper limit for * pulverized coal grain size is Calculations based on furnace trials have shown that pulverized coal can replace up to 30

The report on Pulverized Coal Injection System Market provides qualitative as well as quantitative analysis in terms of market dynamics, competition scenarios, opportunity analysis, market growth, etc. for the forecast year up to 2029.
Pulverized Coal Injection. ... In this instance PCI technology is used in the steel making process to replace up to 50% of the coke charge used for smelting, with the far cheaper fuel, coal, offering a lower cost, more efficient and more environmentally friendly system. Download.
Pulverized 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 furnace.
Pulverized Coal Injection (PCI) System A simple and lowcost PCI system NIPPON STEEL ENGINEERING CO., LTD.''s PCI system is superior in terms of (1) supply record, (2) function (circumferential balance of the injected pulverized coal), and (3) cost.
Pulverized Coal Injection (PCI) systems of the original Sumitomo design, developed in, are now in successful operation on three blast furnaces at Sumitomo Metal Industries. Because mechanical coal feeders have limited capacity, however, multiple units would be required for high injection .
Coal injection system. Reduced pollution Coal grinding and injection systems are nonpolluting systems. Injecting pulverized coal into a blast furnace reduces the overall pollution made by coke production. Increased productivity Installation of a coal injection system can increase productivity through improved operation of the blast furnace.
Oct 21, 2018· Fig 2 Combustion efficiency and pulverized coal injection rate. Based on the various investigations carried out, the measures to intensify coal combustion in the raceway are summarized below. Enriching the blast with O2. However, the nonlinear effect of blast O2 on the degree of combustion is to be taken into account.
