Why Coke Is Used In Blast Furnace Not Coal?

Why Coke is used in blast furnace?

Coal Carbonization Metallurgical coke, along with iron ore and limestone, is layered into a blast furnace to convert the iron ore to metallic iron.

Coke, which is mostly carbon, reacts with the blast air to produce carbon monoxide, which, in turn, reacts with the iron oxide to produce carbon dioxide and metallic iron..

Why Coke is not used as a fuel?

The term means a product similar to coal and mined the same way. Coal is cheaper and that is why it is used more often. … Coke is cleaner and other methods should be looked into before coal and oil run out.

What is the hottest coal?

Anthracite coalAnthracite coal is the hottest burning fuel in comparison to the most common ones in use. Environmentally cleaner than other fossil fuels. Due to its low sulfur content, Anthracite coal produces virtually no smoke or particulate emissions. This is a major problem with cord wood and pellet burning stoves.

What is difference between coke and coal?

Charcoal is a fuel that comes from the incomplete burning of wood. Coke is a fuel that is obtained from the calcination or dry distillation of mineral coal. … It is composed of carbon and has a high calorific value, but it is highly polluting.

Why is Coke preferred over coal?

Since smoke-producing constituents are driven off during the coking of coal, coke forms a desirable fuel for stoves and furnaces in which conditions are not suitable for the complete burning of bituminous coal itself. Coke may be combusted producing little or no smoke, while bituminous coal would produce much smoke.

Does coal make steel?

Global steel production is dependent on coal. 70% of the steel produced uses coal. Metallurgical coal – or coking coal – is a vital ingredient in the steel making process. … The primary source of this carbon is coking coal.

Which coal has no caking power?

Non Coking Coal does not have any caking properties and it is mainly used as thermal coal for power generation. It has a higher ash content and also used in industries like cement, fertilizer, glass, ceramic, paper, chemical and brick manufacturing.

Is Coke a fossil fuel?

Coal gas, coke and producer gas are the byproducts of coal and are not fossil fuels, except natural gas which is a fossil fuel.

What advantage does Coke have over coal as a fuel?

Solution : (i) Coke produces more heat than an equal mass of coal. (ii) It produces ni smoke on burning and leaves no residue and as such does not cause air pollution.

How do you make coke with coal?

Coal Coke is created by cooking Coal in a Coke Oven. Even though coal coke is produced slowly in the coke oven (2.5 minutes per piece), it is a highly effective fuel as it essentially produces double the heat content of the Coal required to create it.

Which is better coal or coke?

Coke is a better fuel because coke produces more heat on burning as compared to coal. Coke has higher calorific value than coal. When equal masses of coke and coal are bunt, coke produces more heat. Also when coke is burnt, smoke is not obtained whereas coal produces smoke on coal.

What is soft coke?

noun. A black, sparse variety of coke produced by the carbonization of highly volatile coal at a high temperature, typically used in open fires and closed appliances like stoves.

Which coal is used for coke preparation –?

Coking coalCoking 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.

Which burns hotter coal or coke?

What is the difference between coal and coke fuel? Coal is a shiny, black fossil fuel that contains impurities, emits smoke when burned, and produces less heat than coke. Coke is a dull, black byproduct of coal that burns hotter and cleaner.

What is soft coke and hard coke?

Hard coke- hard coke is obtained by high temperature carbanisation. It is used in metallurgy as metallurgical coke. Soft coke- soft coke is obtained by high temperature carbanisation. It is used as domestic fuel for making water gas acetylene. Also it is obtained as a product in the manufacture of coal gas.

Is Coke is a clean fuel?

Coke is used as a fuel and as a reducing agent in smelting iron ore in a blast furnace. The carbon monoxide produced by its combustion reduces iron oxide (hematite) to the iron product. Although coke is more expensive than coal, it can be used in households as a clean fuel, relatively free of smoke and impurities.

Can we make steel without coal?

Well, yes, we can. At present, the ultimate solution is considered to be ‘green’ steel, made with renewable hydrogen. … You see, carbon (in the form of carbon monoxide) is currently the dominant method of converting iron ore into iron.

What is Coke in coal?

By distilling bituminous coal in retorts to obtain gas for illumination, or by burning it in kilns or pits, the residue left behind is called coke, which is simply coal charcoal, and is nearly pure carbon.

What type of coal is used for steel?

coking coalMetallurgical coal, also known as coking coal, is used to produce coke, the primary source of carbon used in steelmaking.

What are 4 types of coal?

Coal is classified into four main types, or ranks: anthracite, bituminous, subbituminous, and lignite. The ranking depends on the types and amounts of carbon the coal contains and on the amount of heat energy the coal can produce.
