If you think you are re-inventing the wheel, perhaps you need to sit down with an adult beverage and re-think your proposal.
Look over the AHS gassification units, and all the European Gassers.....you are stumbling into a minefield, but best of luck to you anyway! .
If you have PLENTY of cash floating around, why not goggle GARN.COM.......Shafer.com......Royall.com......Central Boiler.com, etc.
This is a coal forum, however I'm sure everyone here burned wood at one time or another in their past. We know wood burning also, but for reasons publicly stated here, we are "Black Rock Junkies", but support any form of staying warm that doesn't involve sending your hard earned money overseas, and does benefit American Companies and products. I don't want you to think that you are a 'Cobra slithering in a den of mongoose's, it is not that way. We are here to provide advice, and how you use it is your choice. PS: There are some extremely competent individuals on this forum, so consider yourself amongst friends!
PPS: Ever think of coal as a fuel you could learn to like? You sure seem to have a thirst for knowledge....and you are in the right place to get just that. Ask away.........after you enjoy that 'adult beverage'............
