  • Pelletizing Wikipedia

    The configuration of iron ore pellets as packed spheres in the blast furnace allows air to flow between the pellets, decreasing the resistance to the air that flows up through the layers of material during the smelting. The configuration of iron ore powder in a blast furnace is more tightly-packed and restricts the air flow. This is the reason

  • Direct reduced iron Wikipedia

    The advantage of the bloomery technique is that iron can be obtained at a lower furnace temperature, only about 1,100 °C or so. The disadvantage, relative to a blast furnace, is that only small quantities can be made at a time. Chemistry. The following carbothermic reactions reduce iron ore to iron.

  • Iron ore pellets and Pelletizing processes IspatGuru

    Advantages of Pellets. Iron ore pellet is a kind of agglomerated fines which has better tumbling index when compared with the iron ore and it can be used as a substitute for the same both in the blast furnace and for DR production. Pellets have good reducibility since they have high porosity (25-30%). Normally pellets are reduced considerably

  • why sinter is used in blast furnace

    Why is sinter used in a blast furnace? Quora. If particles of such sizes are directly used in the blast furnace for obtaining iron, they would choke the tuyeres and may even cause explosion inside the blast furnace. Thus a sample of adequate size is required to be used in the blast furnace . Hence sintering is done inorder to use the cheap

  • What are the benefits and disadvantages of a pellet stove

    The price of a pellet stove (from €900 and up to more than €5,000 for models with accumulator in stone) is higher than that of a simpler classic stove (from €100). On the other hand, this price is comparable with that of a classic high-efficiency fireplace with mechanical adjustment and smoke extraction.
