Оценител на добива на дърва за огрев

Оценете колко дърва за огрев, подреден обем и чували можете да получите от диаметъра и дължината на трупите, целевия размер и процента дефект.

Превключвайте между кръгли и разцепени дърва, докато настройвате фактора на подреждане и капацитета на чувалите.

Планирайте трупите и дървата заедно Многоезичен и с много единици Показва броя чували на същия екран Всички изчисления остават в браузъра

Предупреждение за безопасност

This tool estimates quantities only. Do not use it for safety decisions about cutting, splitting, moving, or loading logs.
Check machine capacity, protective equipment, storage conditions, and local regulations separately.

Как се използва

1

Enter the log count, log diameter, log length, and defect rate.
2

Choose the firewood shape, then enter the target length and cross-section.
3

Set the stacking preset and bag capacity.
4

Review pieces, stacked volume, and bag count in the result cards.

Примери

Standard round firewood

Input

10 logs, diameter 280mm, length 3.6m, defect 12%, firewood length 330mm, diameter 80mm, stacking factor 0.70, bag 100L

Output

About 1,176 pieces / about 2.79 m³ / about 27.9 bags (purchase guide 28)

Imperial site example

Input

8 logs, diameter 10in, length 8ft, defect 10%, firewood length 16in, width 4in, thickness 4in, stacking factor 0.65, bag 3.5ft³

Output

About 212 pieces / about 48.3 ft³ / about 13.8 bags (purchase guide 14)

Формули

Log volume = π × (diameter ÷ 2)^2 × length × log form factor
Usable volume = log volume × log count × (1 - defect rate)
Pieces = floor(usable volume ÷ one-piece volume)
Stacked volume = finished firewood volume ÷ stacking factor
Bags = stacked volume ÷ bag capacity

Бележки

Diameter is treated as an average estimate. Use the log form factor if taper is strong.
Stacking factor and bag capacity vary with site practice, packing density, and firewood size.
Charcoal yield is out of scope.

ЧЗВ

Is the log diameter average or top-end?

It is treated as an average diameter. If you only know the top-end diameter, adjust it to a nearby average.

Are pieces rounded up?

Completed pieces are floored, while bag count is rounded up as a purchase guide.

What if I do not know the bag capacity?

You can still use the piece count and stacked volume. Bag count stays hidden until you enter a capacity.

Can I type values like 8ft or 330mm?

Yes. Each field accepts bare numbers using the selected default unit, and values with a unit suffix.

Does it calculate charcoal yield too?

No. Charcoal production uses different conditions and is out of scope.
