If I have a one tonne (equivalent to 1.167 m3) of residual wood product used in a suspension burner at 3% moisture. The wood consists of a mixture of softwood by-products. How much CO2 would be produced under complete combustion?

    This has the feel of homework. Show us some effort and we will help, but we do not do the heavy lifting. – StainlessSteelRat Oct 05 '22 at 15:39

    What woods? that makes a difference. – Solar Mike Oct 05 '22 at 15:44
  • Figure out the carbon content of the wood in kg. You know (or can look up) the atomic mass of carbon and oxygen so you can work out how to scale up the result from C to CO$_2$. – Transistor Oct 05 '22 at 19:43
  • Thanks @StainlessSteelRat. but it is actually for my MSc. I am doing an LCA on organic fertilizers and one manufacturer uses a suspension burner to emit heat and dry manure... – Georgia Peach Oct 06 '22 at 00:26
  • @SolarMik The wood is OSB residual. They utilize a mixture of softwood from Eastern Canada - ash, pine. l am having difficulty understanding what I need to find. I think its the density of the dry OSB. – Georgia Peach Oct 06 '22 at 00:27
  • Hi @Transistor I knot the carbon content is roughly 50%. but I think that is at wet weight. Because the wood is very dry at 3% mc, wouldn't this mean there would be more carbon ??? This is what I am having trouble with. – Georgia Peach Oct 06 '22 at 00:30
  • Let's clarify some things: 3% moisture by weight? volume? 1000 kg is the gross weight? net weight? something else? – J. Ari Oct 06 '22 at 14:26
  • Its 3% moisture by weight. 1000kg is the gross weight. – Georgia Peach Oct 06 '22 at 15:31
  • If you start with 1000 kg of wood that has 3% by weight water, that means you have 970 kg is wood that can burn. The 50% figure you stated before would apply to this mass. – J. Ari Oct 06 '22 at 17:29
