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.
Why is Coke preferred over coal as a fuel?
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 coke from coal used for?
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.
What is the 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.
What are the important uses of coke?
The most common use of coke is as a fuel for stoves, furnaces and blacksmithing. It is sometimes preferred over coal because burning coke produces very little smoke. It is also used to produce iron in a blast furnace. Coke is used to manufacture steel and many other materials.
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.
Can we make steel without coal?
The key message is this: it is possible to create low-emissions steel, without metallurgical coal. … Not to mention what products we can produce from the steel – adding value in many more ways than just exporting ore – and taking advantage of an increasing consumer demand for low carbon products.
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.
Why Coke is used in blast furnace not coal?
Coke is used as a fuel and a reducing agent in melting iron ore. It is produced by baking coal until it becomes carbon by burning off impurities without burning up the coal itself. When coke is consumed it generates intense heat but little smoke, making it ideal for smelting iron and steel.
What is the main element in Coke?
Is Coke 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.
What is charcoal vs coal?
Coal is a rock you dig out of the ground (that much I knew). Charcoal is a man-made product, and it’s made from wood. … This general process of partially combusting a fuel by heating it in the absence of oxygen is called charring, and it can be applied to coal as well. Confusingly, charred coal is called “coke”.
What is hard coke?
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) in the production of the iron product.
What is the meaning of coke?
distilled to dryness
How is coke obtained from coal?
Metallurgical coke is produced by destructive distillation of coal in coke ovens. Prepared coal is “coked”, or heated in an oxygen-free atmosphere until all volatile components in the coal evaporate. The material remaining is called coke.
What is coal gas used for?
noun. a gas used for illuminating and heating, produced by distilling bituminous coal and consisting chiefly of hydrogen, methane, and carbon monoxide.
