Is PCI metallurgical coal?

Is PCI coal thermal coal?

Pulverised Coal Injection coal (PCI) – coal used for its heat value and injected directly into blast furnaces (without an intermediate coking phase) as a supplementary fuel, which reduces the amount of coke required and therefore costs. PCI coal can also be sold into the thermal coal market.

Which coal is used as metallurgical fuel?

Coking coal, also known as metallurgical coal, is used to create coke, one of the key irreplaceable inputs for the production of steel. There are many varieties of coal in the world, ranging from brown coal or lignite to anthracite.

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.

Is there an alternative to coking coal?

Blast furnaces need coal, but there is an alternative technology called an Electric Arc Furnace (EAF). This is responsible for approximately 30% of the world’s steel production and does not require coal.

Can steel be made without coal?

Now, nearly all new steel globally is produced using iron oxide and coking coal. Coking coal is usually bituminous-rank coal with special qualities that are needed in the blast furnace. While an increasing amount of steel is being recycled, there is currently no technology to make steel at scale without using coal.

Is steel still made with coal?

A third of global steel today is made without coking coal, either through scrap recycling or gas-based steel production; and counting.

Which is a better fuel coal or coke?

Coke is a better fuel than coal because; -Coke produces more heat on burning than coal. -Coke has a higher calorific value than coal. When equal masses of coke and coal are burnt, coke produces more heat.
