In the pulverized coal injection (PCI) process of a blast furnace (BF), intensifying the combustion of pulverized coal in the raceway and tuyere is the key to increasing the injection ratio. 3,4 In addition to widely used technologies that cooperate with PCI, such as oxygen enrichment and high temperature of hot blast air, 5,6 the catalytic ...

Pulverized coal injection (PCI) is a special process used in blast furnaces in which pulverized coal is preheated. However, there are few studies on the application of this technology in industry. In this paper, the combustion of pulverized coal in the tuyere of a blast furnace with different preheating temperatures and PCI rates is observed by a …

Hydrogen (H 2) can be co-injected into the tuyere and shaft into a blast furnace (BF) for reducing CO 2 emissions. However, the feasible co-injection schemes and their effects on in-furnace phenomena are not well understood. In this study, a multi-fluid industrial-scale BF model is further developed to investigate the impacts of H 2 co …

An increased PCI injection level during the blast furnace process would lead to decreased CO. 2 emissions of an integrated steel mill due to a reduced coke consumption and production. In addition, coking coals, which are essential to produce blast furnace coke for steel mills, represent a critical raw material with a limited global availability ...

In this study, we evaluated the influence of using part CO 2 gas instead of air in hot blast on a blast furnace. First, CO 2 gas entered the raceway zone, where it reacted with the carbon in coke or pulverized coal to form CO gas, accompanied by the endothermic effect. Therefore, it was necessary to quantitatively analyze the influence of ...

When the antimony smelting slag contains Pb ~1.2%, Zn ~6.9%, and Sb ~1.4%, the metal recovery of Pb, Zn, and Sb after fuming and volatile process will be 95%, 88%, and 60%, respectively. Meanwhile, the coal consumption is ~0.3 t per ton antimony smelting slag, when the pulverized coal with 59.92% fixed carbon is utilized as …

Furnace permeability was expected to limit the ability to reduce coke rate any further. 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.

Pulverized coal injection (PCI) is employed in blast furnace tuyeres attempting to maximize the injection rate without increasing the amt. of unburned char inside the stack of the blast furnace. When coal is injected with air through the injection lance, the resolidified char will burn in an atm. with a progressively lower oxygen content and ...

To rationally utilize biomass as an auxiliary fuel for pulverized coal injection (PCI) technology, the process of co-injection of bio-syngas/coal into the blast furnace (BF) is designed. In this paper, a 3D CFD model with double lance is established to investigate the co-injection of bio-syngas/coal in the BF. The effects of bio-syngas injection rates and …

reduction through equipment integration has also been demanded, requiring a high blast furnace production rate, which increases the risk of operational problems such as gas channeling due to excessive pressure drop of the furnace. While the blast furnace operation becomes difficult, the working population is expected to decrease in …

Abstract: Pulverized coal injected into a blast furnace (BF) burns incompletely in a very limited amount of time. A considerable amount of unburned pulverized coal (UPC) escapes from the raceway to the coke layer. The unburned pulverized coal reacts with CO2 in the coke layer, and this has a very significant impact on the operation of the BF.

The injection of pulverized coal into a blast furnace can replace coke, reduce the cost of pig iron, and enrich reducing gas. It has become the prevailing technology in the blast
