Recycling of Blast Furnace Dust in the Iron Ore Sintering

the average rate of BF dust recycling at European sinter plants is 12.7 kg/t of sinter. In the sintering process coke breeze is used as fuel to sup-ply the thermal energy for sintering the feed material. At the start of the travelling grate, called the sinter strand, a canopy of gas burners ignites the coke breeze in the mixture. In the

Recycling of Blast Furnace Dust in the Iron Ore Sintering

The coke breeze consumption is in the range of 44 kg to 64 kg per ton of sinter. 8) The carbon contained in the recycled BF dust is also combusted during the sintering process. Thus, the coke breeze addition to the sinter feed mixture can be reduced. However, a sufficient addition rate of fuel is crucial for sinter quality and the carbon replacement factor is not known for coke with carbon of BF dust which

Coke Breeze Anode Backfill by Asbury Graphite Farwest

Why Coke Breeze Backfill? With the right coke breeze backfill, anode-to-earth resistance is decreased, since the backfill column functions as the anode rather than just the anode material itself. Gas blockage and drying tendencies are decreased by the increased anodic reaction surface area. Anode life is increased by the shift of the oxidation reaction from the anode surface to the backfill surface. Also, the

Coke Breeze Anode Backfill by Asbury Graphite Farwest

Five Coke Breeze Backfills. Asbury 218-L Backfill is an industry standard calcined petroleum coke. It is a perfect choice in situations where backfill must be top loaded. The density and angular nature of Asbury 218-L allow it to settle quickly into position. Asbury 218-L is a coarsely screened product. The large size of the particles ensures that the backfill will be permeable to gas even in

The sintering process converts fine-sized raw materials, including iron ore, coke breeze, limestone, mill scale, and flue dust, into an agglomerated product, sinter, of suitable size for charging into the blast furnace. The raw materials are sometimes mixed with water to provide a cohesive matrix, and then placed on a continuous, travelling grate called the sinter strand. A burner hood, at the

Ensuring Efficient Handling of Coal & Coke Products

Dust. Dust is a frequent challenge with coal and coke products, with some forms being more prone to dust issues than others. In addition to being a nuisance and resulting in product loss, dust can be a hazard in the work environment, and also poses air pollution and safety liabilities. For this reason, ensuring proper dust control is a major objective when working with coal and coke products

Coke (fuel) Wikipedia

Coke is a grey, hard, and porous fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.. The unqualified term "coke" usually refers to the product derived from low
