Understanding Pulverized Coal Injection in Blast Furnace

10/21/2018· 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.

Blast furnace ArcelorMittal in Belgium

At the bottom of the blast furnace, hot air with a temperature of 1.000° C to 1.200° C is blown into the oven. The hot air reacts with the coke and pulverized coal, and forms a reduction gas, which abstracts the oxygen from the iron ore. At the same time, the heat melts the reduced iron ore.

Pulverized Coal Injection in a Blast Furnace IspatGuru

5/10/2013· Pulverized Coal Injection in a Blast Furnace 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.

Why Use Coke for Blast Furnace Ironmaking not Use Coal

In blast furnace ironmaking coal is not as strong as coke, and crushing will cause a decrease in the permeability of the blast furnace. The calorific value and carbon content of some anthracite coals are higher than coke, but there are more harmful impurities such as phosphorus and sulfur in coal.

Blast Furnace an overview ScienceDirect Topics

BFG is a by-product of the chemical reduction of iron ore in blast furnaces. It typically contains about 20–30% carbon monoxide (CO) and about 2–6% hydrogen (H2) as combustible components, and a significant amount of inert gases with about 45–60% nitrogen (N 2), and 20–25% carbon dioxide (CO 2) (see Table 14.1).

Blast furnace Wikipedia

In a blast furnace, fuel, ores, and flux are continuously supplied through the top of the furnace, while a hot blast of air is blown into the lower section of the furnace through a series of pipes called tuyeres, so that the chemical reactions take place throughout the furnace as the material falls downward. The end products are usually molten metal and slag phases tapped from the bottom, and waste gases exiting from the top of the furnace

Mechanism of La2O3 as combustion improver in blast

The coal injected into the blast furnace was a pulverized mixture of bituminous coal and anthracite coal, the compositions of which are shown in Table 1. The pulverized coal mixture contained 30 % No. 1 anthracite coal, 30 % No. 2 anthracite coal, and 40 % bituminous coal. The particle size of the pulverized coal mixture was less than 0.074 mm.

Coke (fuel) Wikipedia

The coal is baked in an airless kiln, a "coke furnace" or "coking oven", at temperatures as high as 2,000 °C (3,600 °F) but usually around 1,000–1,100 °C (1,800–2,000 °F). This process vaporises or decomposes organic substances in the coal, driving off volatile products, including water, in the form of coal-gas and coal-tar.
