operating domestic blast furnaces employed the pulverized coal injection equipment, which increased the average domestic pulverized coal ratio to a 130 kg/t level, (Fig. 2). Table 1 shows the various types of injection for the blast furnace pulverized coal equipment. Table 2
Pulverized coal injection (PCI) is a well-established technology for hot metal (HM) production in a blast furnace (BF). It is practiced in most of the BFs and all the new BFs are normally built with PCI capability. The composition and properties of the coal used for injection can influence the operation, stability and productivity of the BF ...
It is a page of the detail of Pulverized Coal Injection (PCI) System for Blast Furnaces of Steel Plantech.Design, manufacturing, installation, sales and after-sales servicing of steelmaking machinery, non-ferrous metal producing machinery, and coke-making machinery as well as related equipment for use in Japan and overseas
In addition, the relative cost of coal would be significantly lower than the cost of coke it replaced. This lead to the decision late in 1991 to install pulverized coal injection (PCI) equipment for all of Inland`s blast furnaces.more » « less
Pulverised coal injection (PCI) is a well established technology. It is practised in most, if not all, countries with coke-based 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
We have multiple core technologies of green metallurgy with features of energy-saving and emission reduction, and the qualification of designing, contracting and installation of pig iron, ferronickel, ferromanganese smelting blast furnace of 20~ 550m³, auxiliary sintering machine, coal powder injection system, pellet shaft furnace, lime kiln ...
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 for reactions in the blast furnace.
Reliable, efficient and accurate injection of auxiliary reducing agents is vital for cost effective blast furnace operation. Paul Wurth is involved in the development and application of all forms of gaseous, liquid and solid reducing agents injection via the hot blast tuyeres.
Blast Furnace Granular Coal Injection (BFGCI) Process at Bethlehem Steel’s Burns Harbor Plant in Burns Harbor, Indi-ana. The technology is installed on Blast Furnaces C and D, each of these units hav-ing a production capacity of 7,000 net tons of hot metal per day. In the BFGCI process, granular coal is injected into the blast furnace as a fuel supplement. The coal, along with heated air, is ...
means separate injection equipment must be installed and reducing agents can only be used at designated tuy-eres. To increase recycling, the gasification behavior of waste plastics should desirably be as similar to that of pulverized coal as possible. It is also necessary to pul-verize the waste plastics to an appropriate particle size and inject the plastic material into the blast furnace in ...

By 1993, several changes in key conditions provided the impetus to install equipment to inject coke oven gas into the blast furnaces. This paper describes the planning and implementation of a project to replace natural gas in the furnaces with coke oven gas.
Accordingly, the Pulverized Coal Injection (PCI) method is becoming an internationally popular method for improving blast furnace operation. Pulverized coal injection method. Pulverized coal injection was developed in the 19th century, but was not implemented industrially until the 1970s.

17.6 Coal injection. Blast furnace coal injection has been used successfully for many years. The rate at which it can be used is governed by factors relating to the properties of the coal, the quality of the coke it is replacing and to the operational demands and constraints of the blast furnace process itself.
ONLINE COAL FLOW MEASUREMENT - A FIRST STEP Blast Furnace Design Blast Furnaces equipped with PCI injection systems have many local modifications to accommodate the on-site designs. In general, they can be described in three different categories, as shown in Figure 3. Figure 3: Blast furnace equipped with PCI PCI Injection System Design
nature of the combustion of coal injected into a blast furnace. The Amanda furnace of Armco and No. 7 Blast Furnace of Inland Steel (put on line in 1993) are two of the three blast fiunaces in North America currently using coal injection and are, therefore, two of the three full-scale testing facilities available.
Pulverized coal injection equipment . Pulverized coal injection tank. Double-tank paralleling type: the upper part is coal storage tank, thelower part is pulverized coal injection tank. The advantages are accurateweighing and high reliability, the disadvantages are large occupied area, muchmore equipment
Blast Furnace and Process Description:- Iron blast furnace is a vertical shaft, which is used to melt the iron ore and to produce hot metal by heat exchange and chemical reaction.The burden charge consisting of iron oxide, flux and coke and it provides through the throat from the top of the furnace.
