Question: Which Is Better Fuel Coal Or Coke?

What is difference between coal and coke?

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..

What is the use of coal gas?

noun. a gas used for illuminating and heating, produced by distilling bituminous coal and consisting chiefly of hydrogen, methane, and carbon monoxide.

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.

Does Coke burn hotter than coal?

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. … However, blacksmiths still rely on coke as an efficient source of fuel for the forge.

Which is the most clean fuel?

Natural GasWhy Natural Gas is the Clean Fuel of Choice 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.

Why do we turn coal into coke?

Coking coal is converted to coke by driving off impurities to leave almost pure carbon. The physical properties of coking coal cause the coal to soften, liquefy and then resolidify into hard but porous lumps when heated in the absence of air. … This process results in a hard porous material – coke.

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)

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 is Coke and its uses?

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 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.

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.

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 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.

What is the best alternative to gasoline?

10 alternatives to the gasoline-powered engineGas-electric hybrids. The first hybrid models, the Honda Insight and Toyota Prius (above) both reached the U.S. in 1999, and today some 40 gas-electric models are for sale. … Plug-in hybrids. … Electrics. … Ethanol and flex fuel. … Biodiesel. … Propane. … Liquefied and compressed natural gas. … Fuel cells.More items…•
