Here are some pictures of the steamer at work. I really do not know all of the specifics but there is a large vat of water that is heated producing steam into the aluminum building. The temperature of the wood is brought up to 200 degrees and held for at least 24 hours. Pictures of building and vessel that holds water and tubing to heat water. We run a large boiler just to provide heat for running two of these steamers. More pictures to come. Please bare with me and ask questions if you like. I’ll try to get answers for you as this is not what I do at work but want to share.
