我如何去除無數小塊木炭?


3

有一小塊土地用來在篝火上燃燒樹枝(因為這是擺脫它們的最簡單方法)。大部分材料被燒成灰燼,但其中一些僅變成木炭。那些木炭的直徑在5至20毫米之間,並與骨灰混合。

每次運行篝火時,都會保留新的木炭碎片,因為以前篝火中殘留的熱量根本不夠加熱,無法進一步燃燒。因此那些木炭在灰燼中堆積。

木炭不會降解-它幾乎是純碳,沒人願意吃-因此它永遠存在。容易將其粉碎,但會產生木炭粉塵。

除了將木炭收集並傾倒在某個地方(看不見,不省人事)之外,我如何擺脫它呢?

我可以將它收集起來(連同一些灰燼,但是隨便什麼),然後嘗試燃燒,但是看起來像是有問題的,因為將這麼小的木炭放在火上是不平凡的。

什麼是除掉木炭的好方法?

You are talking about black gold that has a value of AU$40 per 25 litre bag in my area. I would suggest either selling it or putting it back into the soil.

See https://en.wikipedia.org/wiki/Biochar for uses of charcoal as a soil amendment.

You can collect (cool) charcoal in a plastic bag until you have a volume worth doing something serious with. Because it's pure carbon it will store indefinitely.

Alternatively, if you rake out the old charcoal, set up your new fire, then put the charcoal on top, then I think you'll find that it does indeed burn. Wood ash tends to be very fluffy and acts as a good insulator — which is why charcoal tends to accumulate in a bed of ash. If you separate the charcoal from the ash then it's no-longer insulated, and getting it to burn is much easier.

Whatever you do, don't pour ash onto a fire. That's about the same as throwing sand onto a fire — something that folks do (in a pinch) to put a fire out.

I have used small charcoal bits from my own fire-pit to create small terrariums.

Hard wood ash can be used to make lye.
