Coke is a better fuel than coal because; -Coke produces more heat on burning than coal. … When equal masses of coke and coal are burnt, coke produces more heat. -When coke is burnt smoke is not obtained.
Why is Coke preferred over coal for burning?
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.
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.
Why is Coke considered as 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.
Which is a better fuel and why coal or petrol?
Answer: Coke is a better fuel because it is almost the purest form of carbon. It burns without the smoke and has a high calorific value.
What is Coke vs 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 type of coal has the most energy?
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 type of fuel is Coke?
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 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 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.
Which is the cleanest fuel?
Which is most green as fuel?
Biodiesel and bioethanol are the most common, viable alternatives and infinite green fuels that can be used in internal combustion engine. … The candidates as green fuels have the potential to significantly reduce the greenhouse gas emissions by as much as 30% from their combustion in internal combustion engine.
Which is the least polluting fuel for vehicles?
Compressed Natural Gas (CNG)
