difference between lpg and wood
Answers
Answer:
Explanation:
Therefore, slowly wood is replaced by LPG, which is a liquefied form of petroleum gas. It does not give out smoke and other pollutants and is a cleaner fuel. Again, fuel efficiency of LPG is more than that of wood. The calorific value of LPG is 55000 kJ /kg, while that of wood is between 17000 to 22000 kJ / kg.
Answer:
LPG is better than wood.
Explanation:
Renewable vs Climate Friendly BBQ
Most people would think that a renewable fuel, like wood, is more eco-friendly than a fossil fuel.
However, when it comes to charcoal versus gas barbecuing, the climate friendly choice is not what you may think.
What is Charcoal?
Charcoal BBQ fuel is made from a renewable resource, wood.
Charcoal briquettes are manufactured by heating the wood in a low oxygen environment to remove all the moisture.
The end result is tightly packed little lumps of carbon.
When burnt, this carbon combines with oxygen to create heat and CO2.
BBQ gas is LPG.
Whilst LPG is a fossil fuel, it is also a low carbon energy source.
The LPG (propane) gas molecule only has 3 carbon atoms.
The chemical formula for propane is C3H8.
This means that it does not generate as much CO2 when burnt.
Biofuels do not always result in a smaller carbon footprint than the fossil fuel alternatives.
The problem with charcoal is that it emits almost 3X the amount of CO2 that is produced when you use LPG.
This is harmful because CO2 is a greenhouse gas that contributes to climate change.
To produce charcoal, you heat wood in a kiln.
However, the usable output of charcoal is only around 20-35% of the original input.
The remainder of the wood turns into gas and is emitted into the atmosphere.
In contrast, LPG energy yields are greater than 90%.
The fact that you cannot simply turn a charcoal grill ON and OFF increases the problem.
Charcoal fires need to be started ahead of time and then take time to burn themselves out.
LPG is just a much more efficient fuel for cooking.
