Subject: Re: [Gasification] RH brings up another question....
I wish to run my Kubota WG752 on full load @ 3500 RPM. to deliver
about 13 KW. This should give me at least, 30kw of waste heat with
which to Torrify biomass at an elevated temperature.
The exhaust manifold of the engine is connected to a chamber
containing biomass, having brought the engine up to opering
temperature using natural gas.
The exhaust stream has picked up considerable un oxidized "fuel" on
exiting the torrifyer.
My question is: can this gas stream be recycled?
I have just read through the contents of a very interesting US
Patent,4883570. which describes a device which is capable of
converting this CO2, wood vinegar and tar laden crud into gas and
liquid fuel.
Is this proposal like having the tail wag the dog.? Will there be
any efficiency gains by gasification without oxygen?.
The introduction of steam in the process might augment the hydrogen
content of the gas yeald.
In which case this could be provided from the surplus water being
separated from the product.
There will be a considerable amount of red hot charcoal available.
The bottom line is, will I have utilized 30 KW of waste energy.
Check out the patent.

Wood gasification can happen in as little as 350 c BUT, happens much
etter around the 800c mark.

n my totally uneducated view, the methane,, acetone, etc. are NOT even
n the wood yet as you heat it slowly. You have to get up to the
emperatures where the "destructive distillation" occurs to break down
xisting chemicals into those other components that you list. You need
emps high enough to disassemble and maybe recombine things like the
ellulose and the famous "pyrolignous acids". I'm thinking well over
00C to even start most of those processes.

So if we tossed that example out, and simply heated wood at a gradual
rate, would the distillation order be simply the boiling point of each
olecule?
By rights, then the methane should come out first, but I never see
flames
shooting out of the butt ends (or the worm hole pores) until the
water is
one.
What is going on?
