Re: GAS-L: Small Scale Gasifiers Defined

["John Davies" <jmdavies@xsinet.co.za>]

Greetings to All,

I have been quietly listening recently without commenting. I find the
discussion on terminology quite puzzling.

1. Producer gas can only be manufactured in a gasifier, be it large or
small, stand alone or as a part of a cook stove.

2. When producer gas is burned, I can only consider it to be combustion, be
it large or small, stand alone or as a part of a cook stove.

In the railway world, the Argentinean locomotive engineer L D Porta called
the "Staged Gasification" or a "Close Coupled  Gasifier" as adapted to steam
locomotives, " GAS PRODUCER COMBUSTION SYSTEM" or  GPCS. This made it quite
clear that both processes were involved as opposed to straight combustion of
the fuel. Once again, I do not see any limitation to size in this
description.

I hope that this reference gives food for thought in the quest of finding a
suitable description for stoves using this process.

Regards,
John Davies.
