Dan: About 25 years ago, at a grain producers meeting, we had a chap describe his gassifier being used in grain drying. I have forgotten most of the details, but he was using round bales of straw as fuel. He had what he called a tower, which was a cylinder the size of the round bales and standing vertical. It had a sealed cover on top that he could open to lower the bales in with a crane device. I think it held 3 or 4 bales and he just kept adding from top. He somehow controlled the fire to the bottom 2 or 3 feet, thus the bales just kept settling, as they burned. The gas produced was then fed to the grain dryer. He has long since passed away, as have most of the guys who worked on the farm. His family still operate the farm. Send me an e mail, my e mail is exposed, just click on my name. I do have the e mail address of one guy that worked on that farm back then. I will send him an e mail, see if he can tell me if there is anyone still around, that either currently still operates this or at least knows how it operated. Another option that may take you to this is do a search. You may find this under Nova Scotia Dept of Agriculture or Lyndhurst Farms Ltd. Lyndhurst is the name of the farm and they do have a web site. I have looked at their site few times, can't say I've ever seen anything on the gassifier. I'm sure interest in this, even if not in use will have been rekindled by current energy prices, thus Dept of Agri. may be a good option. Those guys down there have to dry all their grain. Good luck and come back if you need help.
