Your question: Why is CNG more efficient than fuel like coal?

Why is CNG a better fuel than other fossil fuels?

Compressed natural gas is a clean-burning fuel. It is actually the cleanest of all fossil fuels. … CNG also produces 45% less hydrocarbons than gasoline. And although natural gas also produces greenhouse gases, it is considerably reduced compared to gasoline or diesel.

Is CNG fuel better than coal?

CNG is compressed natural gas. … if a fuel like coal is burnt it leaves out harmful gases like carbon monoxide and also causes pollution. CNG doesn’t cause pollution. CNG can be easily stored in cylinders while coal needs space comparitively.

Why is natural gas more efficient than coal?

Natural gas is often described as “clean burning” because it produces fewer undesirable by-products per unit energy than coal or petroleum. Like all fossil fuels, its combustion emits carbon dioxide, but at about half the rate of coal per kilowatt hour of electricity generated. It is also more energy efficient.

How clean is CNG?

Although compressed natural gas is a fossil fuel, it is the cleanest burning fuel at the moment in terms of NOx and soot (PM) emissions. CNG can be employed to power passenger cars and city busses. CNG passenger vehicles emit 5-10% less CO2 than comparable gasoline powered passenger vehicles.

Why is CNG preferred over LPG?

CNG releases less greenhouse gas, while LPG releases carbon dioxide, but is still cleaner than gasoline. In the case of a spill, CNG quickly dissipates, whereas LPG will settle on the ground. In general, CNG is considered safer than LPG, since LPG is difficult to disperse.

What are the advantages of CNG?

Commonly referred to as the green fuel because of its lead and sulphur free character, CNG reduces harmful emissions. Being non-corrosive, it enhances the longevity of spark plugs. Due to the absence of any lead or benzene content in CNG, the lead fouling of spark plugs, and lead or benzene pollution are eliminated.

Which is the best fuel among coal and CNG?

Which is better domestic fuel? A. CNG B. LPG C. Wood D. Coal

LPG CNG
Constituents are propane and butane Constituent is methane
Calorific value is 90−95MJ.m−3 Calorific value is 35−40MJ.m−3
Used as cooking gas in homes and restaurants Used as refrigerant and automobile fuel
Highly flammable Less risk of ignition

Can CNG be adulterated?

(3) CNG cannot be siphoned off by thieves and (4) CNG cannot adulterated like petrol or diesel. The main problem with switching over to CNG is the difficulty of laying down pipelines to deliver CNG through distribution point or pumps and ensuring uninterrupted supply.

Why do we not use coal gas as a cooking fuel?

Answer : As coal is also a fossil fuel, it is produced in nature from the dead & decayed remains of plants and animals after millions of years of processes. So we cannot use them on a regular basis as a cooking fuel to check their depletion.
