Limestone is added to the furnace as a flux to help remove impurities from the iron ore during the iron-making process. It reacts with the impurities to form slag, which can be easily removed from the molten iron.

What is the function of a furnace heat sensor and how does it contribute to the overall operation of the furnace system?

The function of a furnace heat sensor is to detect the temperature inside the furnace. It contributes to the overall operation of the furnace system by ensuring that the temperature remains at the desired level, allowing the furnace to function efficiently and safely.


Why limestone is used in the blast furnace?

Limestone is used in the blast furnace as a flux material to help remove impurities such as silica, which would otherwise form a slag that interferes with the smelting process. When limestone is added, it combines with the impurities to form a molten slag that can be easily separated from the molten iron.

How is iron refined?

Iron is refined by a blast furnace. A furnace is filled with iron ore, coke (which is charcoal made from coal) and limestone. Huge amounts of air are blasted into the furnace, the calcium from the limestone combines with silicates (which are minerals containing silicon and oxygen) to form slag (which is run off ore from the furnace). A layer of liquid iron collects under the slag, at the bottom of the furnace. The liquid iron is periodically let out to cool. Charlie


What substance are mixed with iron ore in the blast furnace?

Coke (a form of carbon) and limestone are mixed with iron ore in the blast furnace. Coke provides the heat source for the chemical reaction, while limestone helps to remove impurities from the iron ore.


What is the purpose of limestone in the blast furnace?

Limestone is added to the blast furnace as a flux material. It helps to remove impurities in the iron ore by forming a molten slag that floats on top of the molten iron. This slag can then be easily separated from the iron.


What is the function of a furnace inducer motor in a heating system?

The function of a furnace inducer motor in a heating system is to help draw air and combustion gases out of the furnace and vent them safely outside the home.


Which three substances are put into the blast furnace?

In a blast furnace, iron ore (Fe2O3), coke (carbon), and limestone (CaCO3) are commonly used. Iron ore is the source of iron, coke acts as a fuel and reduces the iron ore to iron, and limestone helps remove impurities by forming a slag.
