[Gasification] SPAM: Re: newbie question...

[Tom Miles]

Carbonizing wheat straw  is a challenge. It is very low yield. The straw
itself contains enough air to support smoldering combustion. While it is
likely that the terra preta soils in Brazil were partly from smoldering
grasses the yield in char would have been very low. Having said that it is
both possible and desirable to carbonize grasses. Straw gasification is just
harder to control.  Some big bale size batch carbonizers have been developed
in Australia. A small stale externally heated carbonizer was developed by
ARTI in India. 

 

What scale or capacity are you looking for? Our biochar bloggers on Yahoo
may be helpful.

Hi All,

I am looking for a design for a  pyrolysis unit to convert hay (from wheat)
into bio-char.

Is it possible to convert the hay into bio-char with out using any external
fuel such as coal or gas?

Is it possible to use the hay as a fuel for slow pyrolysis.

please give you feed back.

I think Tom has a methane list somewhere. Maybe:

Pyrolysis gas can have a lot of tar in it. What is your plans for that?

Just joined .. and have been interested in gas from wood pyrolysisfor quite
a while - but also in methane from bio-digestion (small scale) .. and
haven't been able to find a suitable group

Does anybody have some suggestions?
