Moisture content standard in Charcoal and charcoal briquette

Question

1. What is the standard moisture level in the charcoal?
2. How to calculate or measure the moisture content before selling/export?
3. Do you have any easy way to check if the moisture content is o.k.?

Basis of calculation:  % Moisture ( wet weight ) = (weight of charcoal – dry charcoal) x100 /starting charcoal weight.

4. If we have high-tech tools to measure the moisture, what is the favorable level for charcoal / charcoal briquette export.

Please kindly reply

Answer 

Normally, the charcoal / charcoal briquette moisture content should be in range of 7-10 %. However, there are some differences between charcoal (wood charcoal) and charcoal briquette.

1) If the charcoal manufacturer use water to extinguish the fire, then it would be somewhat higher moisture off the stove than to extinguish by closing the kiln, which almost no moisture left. Anyway, Usually charcoal will absorb the moisture in the atmosphere soon after you remove the charcoal from the kiln. If you do not put water directly to stop the carbonization (stop the charring), then the moisture content will not exceed 10%.
Other categories, such as mangrove charcoal imported from Myanmar , most of it will be humid because the sea water or sea water splashing into the boat. The salt is very rich in charcoal.
Ever is the time to send them to the destination. Countries with low humidity, like the Israel, the weight after 1 month storage can loose more than 5-10% in dry season. It has been my experience with clients who have experienced this but they were already aware of this problem at first (that is what I was told).
Conclusion is that rarely do they make it much moisture. But we can check easily and to be aware of is the time to pack a bag or box . If too damp can cause rot box or bag wet . You can test by packing and taking the box/bag under the sun and then, after back into the shade and cooling, open to check it.
Because containers can reach reach 60-70 degrees Celsius during shipping, if travel long distance like to Europe it will be more than 1 month, extreme heating/cooling will cause the problem.

2 ) Charcoal briquette with moisture higher than 10 percent moisture, it will become softened and mushy after a 1-2 day after packing. Thus, carry out a test (same as charcoal case), it is not difficult to know that the humidity is low enough or not.

RHA & RHC ( Rice Husk Charcoal ) Briquette making

Question:

Having gone through your website, we would like to inquire on the plant and machinery available for producing briquette out of rice husk ash.

We have rice husk based boiler at our brewery and there is lot of rice husk ash.
We would like to use these ash to produce briquettes.

Regards

DSCF4673

[Answer]:

Thank you for your question.
For smallest system, You would need mixer/feeder and extruder.
You need to mix the rice husk charcoal with binder in our mixer/feeder before feeding to extruder.
Binder can be starch or flour and mixing ratio is about 5% by weight.

Please let us know if you have further question.

Wood Waste to make charcoal briquette

We work with government Wasteplex reduction planning to reduce wooden waste.

We would like to?convert wooden pallets &? wooden waste of construction to sawdust log.

We need? a cartbonization production line to??convert sawdust log? to be charcoal briquette.

Our targeted daily productivity is 300-500 tones per day.

we have some questions:

1) How many msq should be resevered for production line?

2) How many technician can come to assist the development of production line and operation?

3) Maintenance period?

?

Looking forward to hearing from u soonest!

Charcoal Briquette 1

—– Answer —–

Concerning your raw materials (wooden pallets, wooden wastes), the most difficult part would be carbonization of material (either you make briquette then carbonize it or carbonize materials first before making into briquette).In our case (in Thailand), we normally carbonize the wooden wastes into charcoal before using it directly or making into pellet for better usage (we call cold process). However, before we do so (carbonize those wooden materials), we need to remove nails and other metal. Then the wood materials will be converted into charcoal by conventional kilns (because lowest cost, fair quality charcoal, low maintenance cost of kilns, easy construction, etc). Conventional kilns are either brick type kilns or brick-clay type kilns (we have also metal kilns but not much used due to high corrosion of steel kilns resulted from wood vinegar generated during carbonization process).Also, the reason why we carbonize wooden wastes prior to making into briquette is that we can reduce the amount (weight) of wastes after carbonization to less than 30-35%. Then the handling will become easier and less amount. The power required to make charcoal chunk into briquette is much less than making wooden wastes into sawdust and then making into briquette and carbonize it later. The total cost of charcoal briquette making can be 10 times or more different from making them into sawdust first. FYI, machine size for making 150-200 kg/hr in charcoal case is 10 HP, comparing to sawdust case is 40 HP with heater. Maximum temperature (excluding carbonization) in case of sawdust is about 250-270 degree Celsius (we call hot process), compared with 60-70 degree Celsius in case of making into charcoal first.

The sawdust case also requires dryer, shredder, and other related machines too at the original amount capacity (compared with weight reduction about 1/3 in case of making into charcoal first). You can imagine how complicated and difficult between these 2 processes.

Actually we own both factories (maximum of about 600 kg/hr briquetting machine). The maximum capacity in the video file you mentioned in your first e-mail is about 1,500 kg/hr.

Please refer to attached production scheme between these 2 processes.

That is why we need to understand your raw materials.

Please give us comments and we will get back to you asap.
