Subject: GAS-L: Questions about gasification


All,

I anticipate building a gasifier system in the not too distant future and
two questions keep arising about my "mental" plans.

1) Virtually all gasifirer designs I have seen have been cyndrillical or
drum shaped.

>Is this due to availability of drum shaped containers, to avoid bio mass
"bridging", ease of construction, other, or all the above?

Yes, yes, yes, yes, yes, and yes.

One of the "other considerations" is gas flow....... hard to get gas to flow
to the corners.

>I envision a retangular hopper with a triangular grate/reaction/pyrolisis
chamber. Am I crazy?

Why would you want to do this?
2) Rather than using the gas at the time of generation, I plan to compress
it (similar to LPG) for use later or as needed.

> Is there compelling reasons for NOT doing this?

Yes, indeed. The capital, energy, and maintenance costs associated with a
compressor.

>I anticipate compressing to 180 psi at ambient temps (30 to 90 F) in order
to avail myself of commonly available LPG valves, tanks, fittings and
gauges.

180 psi isn't much. You will need very large tankage to store a decent
amount of energy.

What do you want ot use the gas to accomplish?

Kindest regards,

Kevin CHisholm

Thanks for any responses in advance.
