Biomass is a renewable and potentially carbon-neutral energy source and can be a
promising alternative to fossil fuels in the ironmaking industry. Pulverised biomass injection …

An ironmaking blast furnace is a complex multiphase flow reactor involving gas, powder,
liquid and solid phases. Understanding the flow behaviour of these phases is of paramount …

Hydrogen can be injected into blast furnaces (BFs) via tuyeres and fully replace pulverised
coal injection (PCI) for lowering carbon emission, but hydrogen combustion in the raceway …

Raceway is a key region in ironmaking blast furnace (BF). While the raceway depth is
extremely difficult to measure, thermal images near tuyeres may be available. In this study …

In the lower part of an ironmaking blast furnace, a hot air jet is injected horizontally into a
bed of coke particles, forming a void zone, called a “raceway”. In this paper, two-fluid gas …

Experiments and simulations are conducted to explore the changing laws of blast furnace
(BF) raceway morphology and pressure drop with cylindrical particles. Experimental data …

A previously developed one-dimensional mathematical model, to explain raceway
hysteresis, is used to predict the raceway diameter in operating blast furnaces and hot …

The multiphase flow of gas and fines in a packed bed proves to be an adequate
representation that can reproduce various phenomena observed in complex packed bed …

Using coke oven gas (COG) as a cost-effective alternative fuel in the ironmaking blast
furnace has gained considerable attention. However, its dynamic impact on the raceway's …

The moving-bed gasifier of solid fuels (eg, coal or biomass) is a key chemical reactor to
convert coal or biomass to clean fuel, where the profile of the raceway cavity and its flow …
