A challenge that we face here at the school is the rising cost and difficulty in getting good forging coal. The cost has doubled in the past three years; what hasn’t right? So I had the thought and have been researching and developing plans for building a charcoal retort out of recycled materials. What has developed is quite interesting. With the fabricating abilities of our school we fabricated the retort out of a 330 gallon oil tank, 2 – 100 pound propane tanks, 10 feet of old but good exhaust pipe and some scrap plate and flat stock.

 

Our goal is to produce charcoal out of pallets. Maine Oxy Supply Co.; our main benefactor has so many pallets that they actually have to pay some one to get rid of them. We can fire the retort with the pallets as well as using the nail-free clear wood for making charcoal out of, kiln dried hardwood for free. We also made some contacts with the local timber framers who gifted us all of the scrap from their operations, nice solid pine and spruce.

The idea behind the retort is to capture the wood-gas produced when the temperature of the wood in the chamber reaches 752 degrees Fahrenheit. This wood gas is then introduced into the furnace, burning gasses to fire the retort itself. Here you can see the horizontal disturbance in the flames, actually the force is so great coming out of the burner tube that it burns over a foot away from the tube.

                                                

We are still learning the burn times for various thicknesses of wood and conditions of the day. It is typically taking one hour to bring the chamber to the right temperature and then when the smoke disappears the gassing has started. From then, the one hour mark it fires for another 3 hours eating another 4 or 5 pallets. So in the 4 hour period we can produce 40 pounds of charcoal. We are also studying the burn rates of charcoal verses coke in our forges, we’ll let you know how we make out.

  2. I not to mention my pals were actually checking out the good pointers found on your web blog and at once came up with a horrible suspicion I had not expressed respect to the web site owner for those techniques. My ladies came for that reason excited to read all of them and have actually been enjoying these things. Appreciate your being quite helpful and for selecting certain ideal things most people are really wanting to be informed on. Our own sincere apologies for not saying thanks to you sooner.
