I can't find out how to edit the post, but xxxxx it. I give up. Again, please delete my posts and my account. Thanks

Kk, Zinc boils down to zinc oxide which then burns around 2200 degree Celsius which when burnt releases noxious fumes...whatever. Thank you to the member who did inform me the greenish residue is a result of zinc boiling. I am planning an iron Woodgas stove now because of your answer. I didn't post here to discuss galvanized dangers. I only wanted to see if there was interest in this design and if people who forge and melt metals regular would like to see me further my research. It's expensive to build so many prototypes over 3 years to get this far and I haven't found enough support to continue my research or I need to focus in other uses besides forging, melting. According to the threads I posted in, there seemed to be interest in the idea and I apologize to the community for spamming those topics. I was overexcited that I had found a solution to skipping making charcoal and using straight wood to reach very high temp with charcoal as a byproduct instead of main fuel.

I made a woodgas forge that works pretty dang well. In this video the initial fire smokes for 30-40 seconds and after that there isn't any smoke. I was able to melt a large chunk of aluminium and a piece of copper very quickly. This stove burns on wood chips and a squirrel cage fan. There is no insulation or bricks used in the design. I admit the efficiency for forging isn't optimized as far as the amount of heat that is allowed to escape out the top. One nice thing about using this set up is that after the burn you are left with copious amounts of charcoal. At certain times I am getting a very distinct ugly green residue on my pot and anything inside of it and I have no idea what that is. If anyone knows please advise me. BTW - Yeah, this stove is galvanized metal which has major concerns for welding but not for wood burning fires that do not heat up high enough to vaporize Zinc Oxide which causes the chills. Either way - please understand the concept and don't get fussy about the materials used cause that can all be changed. This you tube video has been removed by the user. Here's another look at the stove as it burns in the daytime on the same wood chips and same fan. This you tube video has been removed by the user.
