The type of gasifier I'm showing you today is what is called a "stratified downdraft gasifier." This name is because of the operation of the fire tube. This is where the fuel is preparing to be burned in the shaker grate. So that'll be the determining factor in how long you'll be able to go in between refueling. Build it as big as you'd like! In my research, the general rule of thumb is that 20 pounds of wood is the approximate equivalent energy of 1 gallon of gasoline. Anything that somewhat guides anything into the fire tube would be fine haha. I'll start explaining from the beginning of the process to the end.įirst stop? Fuel storage! A simple feeding hopper with sides that are steeper than the angle of repose for the highest friction coefficient fuel you could possibly use is ideal. The main parts can be labeled and explained in general terms while still conveying the ideas pretty easily. Gasifiers work on some very simple processes, so there is quite a bit of flexibility in the construction. It certainly doesn't take anything away for this, but I thought it was worth mentioning. I used photos pulled from the video footage. I apologize for my hands being present in some of the photos. Perhaps even improve on it!! The nice part is, they're quite cheap to make if you use re-purposed materials! Supplies The principles are quite simple and I believe that most, with some workshop knowledge and tools, should be handily capable of replicating this. So, in this video and Instructable, I'll be showing off the final product of just a week or so of work. I am very much hoping to spread some awareness and educate those interested in the topic through this brief effort. It doesn't take much thinking to realize the potential usefulness here. There's debris everywhere and most of it will be ripe for the picking to be utilized in a gasifier to generate power. Many preparedness minded people are still drawn to them because of the potential for sustainability in a world where fuel might not be as easy to get. The versatility of gasifiers still remain however. The technology was soon forgotten because of the inherent convenience of liquid fossil fuels once it was more readily available. More recently, in WW2, gasifiers were not an uncommon sight to see attached to the backs of cars, trucks, and tractors as a result of the fuel shortages. Back in the 1800's, coal was gasified for the production of town gas used for lighting, heating, and cooking. ![]() Gasification for use in producing energy has been around for longer than some might realize. ![]() I also chose to stay away from media type filters with this design to practically eliminate maintenance aside from emptying the accumulated liquids in the collection jar. With this second machine I have been able to reduce the unit size and use what I learned to make the process more efficient. I use mine occasionally for generating electricity when the need arises. So in this video and Instructable, I show you how I built my new and improved homemade gasifier out of parts I could find for little to no cost. The blower wasn't able to move enough air, the unit was over-sized for the amount of gas produced, and the gas wasn't cool enough upon exiting the gasifier, resulting in an unsatisfactory amount of condensate getting to the engine. I made this gasifier a couple of years ago now as a second attempt at the technology.
