Jim Mason could you please review this Torsten Kalle paper " The making of the Kalle-Gasifier" for inclusion. I believe it is open source.

Did the previously posted
prove to be copywrited/licenced or did it just get lost in reformatting? Would work well on the All Power site as "BASIC".
Thanks Steve Unruh

steve, i already have this paper up on the main gek info site. see here: . yes, the kalle paper is a work of elegant engineering to ponder and imitate. his solution will only work for char, but the ideas in the unit, as well as the paper, are deeply impressive.

there are a variety of high value papers, books, sizing info and other things on the above page. i will in time be migrating all this and a much larger giant pile of other info to here. (actually, if you are bored, you can migrate it stephen . . . ;-). i have folders and folders of these types of resources, but so far hours have not allowed to a thorough migratory deluge.

in time, we'll have here a large curated library of high value resources for all aspects of gasification. in the interim, i tend to just post things as questions or other work surfaces them.

Yes Jim, I apologize. I found your Kalle paper listing after I had posted my comment. Then read the Lutz paper and rebuttal. Not bored - frustrated, snow the last two days - too cold to weld. Firing Marcus B.s GEK v1.0 I observed tar circulation in the pyro/oxidization section as a doughnut shape. The Finnish monorator paper describes this doughnut heat circulation and now Mr Kalle is describing a doughnut shaped heat/char circulation potential in the reduction area. You DID design this unit with a upper and lower central air injection potential. Kalle cooled his central nozzle with engine exhaust CO2. An Australian fellow named Kurt G. Johannsen used water injection to do the same with his central air jet and the Kalle rebuttal author(?) verifies the heat potential and and gas improvements to do this. Plus we do have Monel metal today. Central plumbing would keep the heats concentrated in the center to encourage these heat circulation patterns and keep the highest heats off of the cooler walls for easiest heat conservation and recycling strategies. Even if I had the skills to help with information cataloging I live in a 40 kps dial-up world. Sorry. Steve Unruh
