[Stoves] wheat husk pellets

[Crispin Pemberton-Pigott]

Dear Bjarne

 

>Any reasonable commercial production of fuel pellets will require pellet
mills that are designed for that, and they are somehow more expensive.

 

The Chinese are looking very hard into this and have an aggressive pelleting
programme that gives tons output per year as the metric. They have major
problems with equipment at any price. Teams are working on how to solve the
materials and wear issues. This was reported in detail at the conference in
October last year at the China Agricultural University, Prof Dong in charge.

 

The economic are strongly affected by transport issues of the product, and
the cost of replacing wearing parts, even when made from tungsten materials.
Agricultural wastes are very dirty and abrasive. If you want to make char,
make it from the uncompressed materials just as AD Karve suggests. If you
want to make fuel, try to get the best materials and pellet or briquette it.

 

If you want to generate power from the char making process, no problem
though the infrastructure required would be a problem.

 

Incidentally the processing centres that take in the agri-wastes do not get
involved in the transport of the materials from the farmer to the centre.
That is up to the farmer who is paid for the material, delivered. 

 

Regards

Crispin
