Quick Answer: Why coal Cannot be used in blast furnace?

Can you use coal in a blast furnace?

Pig-iron production with charcoal in blast furnaces requires approximately the same amount as coke, 0.7 tons per ton. … Charcoal from dense woods performs as well as coke in blast furnaces and can be used in units up to a capacity of at least 400 tons per day.

Why coke is used instead of coal in blast furnace?

The single most important factor is strength ( mechanical compressive ); coal is heated to make coke, the resulting coke is stronger than the original coal. Also, coke helps to make the charge of iron oxides and limestone more porous to permit gas flow up and droplets of liquid iron and slag down.

Why coal is used in blast furnace?

Metallurgical coal produces strong, low-density coke when it is heated in a low-oxygen environment. … The strength and density of coke are particularly important when it is used in a blast furnace, as the coke supports part of the ore and flux burden inside the furnace.

Which coal is used in furnace?

Anthracite coal burns efficiently with no odor or smoke and by heating water rather than air, a coal burning furnace loses less heat. To get an idea of how much high quality coal can produce, one ton of anthracite coal equals about 8,200 kilowatt hours of electricity.

Can you put sand in a blast furnace?

Blast Furnaces should be able to smelt sand, Netherrack, cobblestone, and stone-related blocks faster, not just ores. … Normal furnaces should be just a low-tier furnace for the first hours of a world, and they should be replaced by smokers and blast furnaces.

Why coke is not used as fuel?

Answer: because fuel has different properties than coke as fuel can help a car move and coke can’t do do that as it does not have the chemicals to complete that task …

What is difference between coke and coal?

Coal is a lustrous, black fossil fuel that includes impurities, generates smoke, and generates less heat than coke when burned. Coke is a dingy, black coal waste that burns hotter and cleaner. … Coke is a fuel made from mineral coal that has been calcined or dry distilled.

Is coke obtained from coal?

Coke is produced by heating coal at high temperatures, for long periods of time. This heating is called “thermal distillation” or “pyrolysis.” In order to produce coke that will be used in blast furnaces, coal is usually thermally distilled for 15 to 18 hours, but the process can take up to 36 hours.

What fuel is used in blast furnace?

The iron blast furnace uses carbon as a fuel to meet the energy requirements of the process as well as a reducing agent for smelting the iron ore to pig iron. The most widespread form of carbon used for this purpose is metallurgical coke.
