Solid úttak from dry wood
Start with oven-dry or áætlunning dry wood weight and get charcoal, fines, ash, and residual loss in one view.
Charcoal Yield Reiknivél
Estimate charcoal, fines, ash, and residual loss from dry wood weight, kiln type, target charcoal grade, and feedbirgðir group.
The model is meant for áætlunning. It helps you bera saman kiln options, feedbirgðir mixes, and charcoal grades without leaving the browser.

Safety notes
- This reiknivél is for áætlunning only. It is not a guarantee, certificate, or compliance judgment.
- Follow your kiln safety rules, ventilation procedure, and fire control practice first.
- Use dry wood weight, not wet or freshly cut wood weight.
- Bera Saman jobs with the same dry basis, unit, kiln type, and feedbirgðir group.
What this verkfæri estimates
Kiln and grade aware
Change the kiln type and target charcoal grade to see how recovery and fines change.
Ready for global use
Work in kg, lb, t, US ton, or UK ton and share the same setup with a URL.
How to use
- Enter the dry wood weight first and choose the working unit.
- Pick the kiln type, target charcoal grade, and feedbirgðir group.
- Yfirferð charcoal, fines, ash, solid recovery, and residual loss.
- Copy the niðurstaða or share the URL when you need the same setup again.
Brick kiln, standard charcoal, mixed feedbirgðir
Inntak Dry wood 1,000 kg / brick kiln / standard charcoal / mixed feedbirgðir
Úttak Charcoal 223 kg, fines 18 kg, ash 10 kg, residual 750 kg
Retort kiln, white charcoal, hardwood
Inntak Dry wood 2,000 lb / retort kiln / white charcoal / hardwood
Úttak Charcoal 485 lb, fines 45 lb, ash 34 lb, residual 1,436 lb
Áætlunning basis and assumptions
Dry wood weight is normalized to kg first, then converted back to the selected úttak unit.
Base solid recovery = dry wood × kiln factor × grade factor × feedbirgðir factor.
Charcoal, fines, and ash are split from the solid recovery by grade-based ratios with small kiln and feedbirgðir adjustments.
Residual loss = dry wood - (charcoal + fines + ash).
Unknown selections widen the range so the estimate stays conservative.
Formulas
Dry wood weight is normalized to kg first.
Base solid recovery = dry wood × kiln factor × grade factor × feedbirgðir factor.
Charcoal = base solids × charcoal share.
Fines = base solids × fines share.
Ash = base solids × ash share.
Residual = dry wood − (charcoal + fines + ash).
Range = value × (1 ± spread).
Glossary
Dry wood weight
The dry-mass basis used for the calculation.
Fines
Small fragments and powder that are not counted as usable lump charcoal.
Ash
Inorganic residue that remains after carbonization and cooling.
Residual loss
Gas, tar, steam, and other losses that do not remain as solid vara.
Solid recovery
The sum of charcoal, fines, and ash recovered from the dry wood inntak.
Range
A conservative high-low band based on the selected kiln, grade, and feedbirgðir.
Algengar spurningar
Why does the same wood give different niðurstaðas?
Kiln type, target grade, and feedbirgðir group change the recovery profile and the split between charcoal, fines, and ash.
Can I use wet wood weight?
No. The reiknivél is built on dry wood weight. If you only know wet weight, convert it before using the verkfæri.
Are the values exact?
No. They are áætlunning estimates. Moisture, species, carbonization control, packing, and cooling losses can all change the niðurstaða.
Do you support tons and pounds?
Yes. The same model works in kg, lb, t, US ton, and UK ton.
What happens when I choose Unknown?
The reiknivél still works, but the range widens so the niðurstaða stays conservative until you can confirm the condition.
Athugasemdir
- This reiknivél is for áætlunning, not certification or guaranteed úttak.
- Dry wood means the basis you use for áætlunning, not freshly cut or green wood.
- Bera Saman jobs with the same unit basis so the numbers stay meaningful across sites and countries.
- Your inntaks, local state, and shareable query stay in the browser unless you copy them out.
