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.
What type of fuel is Coke?
Coke is a grey, hard, and porous fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.
Is Coke a fuel?
Coke is a fuel used in the steelmaking process that is created by heating coal in the absence of air.
What is difference between coal and 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.
Is Coke a secondary fuel?
One of the important secondary fuels is coke. Coke is an important raw material in the blast furnace iron-making. It is a source of chemical and thermal energy in the blast furnace.
Why Coke is not used as 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 Coke in coal?

What is the purest form of coal?
Which is better coke or coal?
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.
What is soft coke?
Soft coke :- Soft coke is obtained by high temperature carbanisation.It is used as a domestic fuel for making water gas and acetylene. Also it is obtained as a by-product in the manufacture of coal gas.
Is coal a tar?
Coal tar is derived from coal. It is a byproduct of the production of coke, a solid fuel that contains mostly carbon, and coal gas. Coal tar is used primarily for the production of refined chemicals and coal-tar products, such as creosote and coal-tar pitch.
What are secondary fuels?
Secondary fuels are fuels that are derived from some primary fuel or fuels through chemical or physical processes. These are fuels that are not found as a natural resource. … This means that secondary fuels are often an intermediate form of energy between the primary energy and the energy services.
What are primary fuels?
For example, primary energy sources include petroleum, natural gas, coal, biomass, flowing water, wind, and solar radiation. Those are the fuels that can be mined, reaped, extracted, harvested, or harnessed directly.
Which is not a fossil fuel?
Coal, oil and natural gas are examples of natural gas. Biogas is the mixture of gases produced by the breakdown of organic matter in the absence of oxygen, usually consisting of certain quantities of methane and other constituents. Therefore, biogas is not a fossil fuel.
