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.
Is Coke used as fuel?
Coke is used as a fuel and as a reducing agent in smelting iron ore in a blast furnace. Coke from coal is grey, hard, and porous and has a heating value of 24.8 million Btu per ton.
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.
Is Coke a type of carbon?
Coke is an almost pure form of carbon. The calorific value (heat energy produced when a fuel is burnt) of coke is about 56,000 kilojoules/kilogram.
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 purest form of coke?
The purest form of Cocaine is a white, pearly product. The powder form of cocaine is a salt, which is typically cocaine hydrochloride.
Can humans turn into fossil fuels?
It’s possible that human remains may become part of organic-rich rocks which could conceivably be used for fuel someday. But the bulk of the fossil fuels we use – oil, coal, gas – come from the remains of plants, algae, or abundant tiny ocean lifeforms like diatoms. … Some fossils are found in coal.
What are 4 examples of fossil fuels?
Fossil fuels include coal, petroleum, natural gas, oil shales, bitumens, tar sands, and heavy oils. All contain carbon and were formed as a result of geologic processes acting on the remains of organic matter produced by photosynthesis, a process that began in the Archean Eon (4.0 billion to 2.5 billion years ago).
What is difference between coke and coal?
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 red hot coke?
When carbon dioxide reacts with red hot coke, carbon monoxide is formed. The balanced chemical equation for this reaction can be written as: Here, 1 mole of carbon dioxide reacts with 1 mole of coke to produce 2 moles of carbon monoxide. … Thus, 0.8 l of CO are formed.
What is foundry coke?
Foundry coke is a high-quality grade of coke, also known as hard coal. … It is a large, strong coke used as a supporting matrix and energy carrier during foundry cupolas to produce cast and ductile iron products.
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.
How Coke is 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 Coke in blacksmithing?
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 ( ). Coke is commonly used as fuel for blacksmithing.
How did old coke ovens work?
In a process known as “coking,” coal was shoveled into beehive-shaped coke ovens insulated with a layer of dirt and then ignited. After laborers sealed the doors with brick and mud, the coal was left burning under low-oxygen conditions for two or three days and could reach temperatures of nearly 2000C (or 3600F).
