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..
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.
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.
Is Coke a solid fuel?
Coke is a fuel with few impurities and a high carbon content, usually made from coal. It is the solid carbonaceous material derived from destructive distillation of low-ash, low-sulfur bituminous coal. … While coke can be formed naturally, the commonly used form is man-made.
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.
Which gas is released by burning coal?
Carbon dioxide (CO2)Carbon dioxide (CO2), which is the primary greenhouse gas produced from burning fossil fuels (coal, oil, and natural gas)
What are the two uses of coal tar?
Coal tar is used in medicated shampoo, soap and ointment. It demonstrates antifungal, anti-inflammatory, anti-itch, and antiparasitic properties. It may be applied topically as a treatment for dandruff and psoriasis, and to kill and repel head lice. It may be used in combination with ultraviolet light therapy.
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.
Is solid fuel poisonous?
Toxic gases from indoor solid-fuel cooking fires put families at risk – UN. … “Smoke from burning these fuels gives off a poisonous cocktail of particles and chemicals that bypasses the body’s defences and more than doubles the risk of respiratory illnesses such as bronchitis and pneumonia,” they said.
Which is hotter coal or wood?
Coal ignites at a temperature more than 100 degrees higher than wood, and it requires a hot bed of wood coals to get it started. Being far denser than wood, coal burns more steadily and longer. … Anthracite coal generates 8 to 10 percent ash per ton – more than wood.
What is the cleanest fuel to burn?
natural gasWhen natural gas is burned, it produces mostly carbon dioxide and water vapor — the same substances emitted when humans exhale. Compared with some other fossil fuels, natural gas emits the least amount of carbon dioxide into the air when combusted — making natural gas the cleanest burning fossil fuel of all.
What is the use of coal gas?
The most significant uses of coal are in electricity generation, steel production, cement manufacturing and as a liquid fuel. Different types of coal have different uses. Steam coal – also known as thermal coal – is mainly used in power generation.
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.
Why is coal gas poisonous?
Poisoning from natural gas appliances is only due to incomplete combustion, which creates CO, and flue leaks to living accommodation.
What are the 3 types of fuel?
Fossil fuels principally consist of carbon and hydrogen bonds. There are three types of fossil fuels which can all be used for energy provision; coal, oil and natural gas. Coal is a solid fossil fuel formed over millions of years by decay of land vegetation.
What is difference 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 is the name for the highest rank coal?
Anthracite. Anthracite is the highest rank coal. It is a black, shiny, hard rock and is not friable. It is low in volatile matter and this makes it difficult to burn in rotary kilns.
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.
