Which one is better fuel coal or coke?

Coke is a better fuel because coke produces more heat on burning as compared to coal. Coke has higher calorific value than coal. When equal masses of coke and coal are bunt, coke produces more heat. Also when coke is burnt, smoke is not obtained whereas coal produces smoke on coal.

Is Coke is better fuel than coal?

In practice it has been found, that, for a small concentrated fire, to melt metals or glass in crucibles, coke is a better fuel to use than bitumen coal, but is not superior to anthracite.

Why is Coke used instead of 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.

Why is LPG considered a better fuel than coal?

LPG is an energy-rich fuel source with a higher calorific value per unit than other commonly used fuels, including coal, natural gas, diesel, petrol, fuel oils and biomass-derived alcohols. This means that an LPG flame burns hotter, an advantage that can translate into higher efficiency.

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.

Can steel be made without coal?

Now, nearly all new steel globally is produced using iron oxide and coking coal. Coking coal is usually bituminous-rank coal with special qualities that are needed in the blast furnace. While an increasing amount of steel is being recycled, there is currently no technology to make steel at scale without using coal.

Does coal contain mercury?

Coal naturally contains mercury, a neurotoxin that can damage the nervous system, the brain and other organs. When we burn coal, that mercury gets released into the atmosphere and ultimately rains down into bodies of water. … Therefore, coal is a massive threat to public health.

What are the characteristics of coal?

Coal is a black, inhomogeneous, organic fuel, formed largely from partially decomposed and metamorphosed plant materials. Formation has occurred over long time periods, often under high pressures of overburden and at elevated temperatures.

Why is LPG preferred over wood for cooking purpose in the kitchen 3 points?

Efficiency: LPG is more energy concentrated compared with wood. … This is because LPG transfers 50% of its energy to the stove compared to the 10-20% of wood.

Why is leakage of LPG easily detected?

Solution. Liquefied petroleum gas (LPG) is odourless, but to detect leakage of the gas, a small quantity of strong-smelling ethyl mercaptan (C2H5SH) is added to it. Ethyl mercaptan has a foul smell resembling that of hydrogen sulphide gas, which can be easily detected.

What is the dirtiest burning fossil fuel?

Regardless of variety, however, all coal is dirty. Indeed, in terms of emissions, it’s the most carbon-intensive fossil fuel we can burn.

What is the dirtiest fuel?
