if you burn 1 Ton of wood , what weight in ashes would you be left with. Please help?

Question

Son's homework!

Answer 1

it's hard to tell, unless you do an experiment. but when wood is burn into ashes, all the density is burned with it. Remind you, ash weighs barely anything, so light wind blows it away. I would guess from a ton of burning wood, it would make 15 pounds of ash.

Answer 2

I'm sure there is a formula used to calculate such things, but, without using a formula, I would guess only a few pounds. The bulk of what burned off is the carbon and other chemicals leaving only the residue (ashes). Another way of saying it is that the bulk of the wood was converted to heat energy, leaving only the ashes.

Answer 3

, Difficult to tell ,
Dry wood ,wet wood, damp wood, ash, spruce, pine ,oak,Temperature, efficiency The list goes on and on ,
Judging by the ashes i carry out of my wood stove i would hazard a guess that for every 10 kilos of wood i put in i just get a handful of ash .measured in grammes. That would translate into about 10-15 kilos for 1 ton.
I have a feeling that 10 kilos would be more correct .Perhaps even less

Answer 4

Hi Leila I would say it depends on the type of wood and the temperature at which it is burned.I would choose any wood burn exactly 1kg record the type of wood the method and heat at which it is burnt then x by 1000 this should give you a pretty accurate result i hope this helps.

Answer 5

depends how you burn it. in an open fire, wood burns completely. if however we decide to make charcoal out of it, all we loose is the water. i seem to remember a figure of 4tons of wood equals around 1 ton of charcoal. so you end up with 1/4 ton for your ton start (1 ton is 20cwt, 1cwt is 112pounds... 1/4 ton is 448lb

Answer 6

You'll have to find out the % of vapour that would go as carbon dioxide and water, then subtract it from 1 ton. That would be the weight of the ashes.

Answer 7

Suggest you burn 1kg of wood and weigh the ashes. Then do the math

Answer 8

i think you have asked a question that's unanswerable due to the fact of heat and what kind of wood so accept a guess that a few people have given you

Answer 9

It would depend on the type of wood and how hot the fire burns.
But in general it is less then 25%, less then 500 pounds.

Answer 10

THIS QUESTON IS WAY TOO VAGUE, YOU'D HAVE TO KNOW THE WEIGHT OF THE WOOD ORIGINALLY AND THE AMOUNT OF ENERGY USED TO BURN IT, THEN MAYBE THE QUESTION COULD BE ANSWERED
