ore pelletization effect on furnace efficiency

The effect of sponge iron chemical composition on energy

Secondary combustion: this burns CO on melt surface and increases furnace efficiency. After metallization, one of the most important elements in sponge iron is carbon content. The presence of carbon in the sponge iron eliminates impurities from coke injection such as ash, sulfur, and volatiles. Get price

Iron Ore Agglomeration Technologies

2017/5/18Until the 1950s of the last century, the oxidized iron ores that were loaded into the blast furnace had granulometries within 10 and 120 mm. However, the depletion of high-grade iron ore sources has made necessary the utilization of concentration processes with the purpose of enriching the iron ore. Because of these processes, a fine granulometry is produced, and thus iron agglomeration Get price

Direct reduced iron

Process Direct reduction processes can be divided roughly into two categories: gas-based, and coal-based. In both cases, the objective of the process is to drive off the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.), in order to convert the ore to metallic iron, without melting it (below 1,200 C (2,190 F)).

Bullet Furnace

A Bullet Furnace is used to smelt ore into metal. It is the most basic of the furnace buildings, with a very small capacity and a poor efficiency. You can use a Bullet Furnace to bootstrap yourself into metal production, but you're better off building a better furnace, such as a Compression Furnace, as soon as you can produce or trade for the materials for one.
