Demonstration Of A Wood Gasifier Making Wood Gas Fuel

Description

Link Knight demonstrated a very simple wood gas generator he built. Wood gas is often used to power gasoline engines in vehicles and stand by generators. You can find Link's Youtube channel here: https://www.youtube.com/channel/UCD8OGNWIK0mzgAQgZPL1EPA Link has a very simple wood gas generator made using a paint can with a copper tube soldered onto its lid. The paint can is filled up with wood chips, dried grasses or saw dust. When you place the can over a heat source flammable gas comes out the end of the copper tube. You can collect this gas in a container for later use. Link used a turkey oven roasting bag to collect his wood gas. I must admit that I was quite nervous about the idea of collecting this gas in a bag but Link assured me that it is actually very safe. He said that the gas is not really explosive until it is exposed and mixed with normal outside air. It took a few minutes for the bag to fill up with enough gas for our demonstration. The gas was a bit cloudy. Link explained that he often pushes the gas up through a container of water which filters the gas some. After filling the bag with gas Link removed the can from the heat source and then took the bag off of the copper tube. When lighting the gas with a match there was a perfect beautiful flame which shot up almost two feet into the air. As Link has told me there was no dangerous explosion and the gas only flamed up after exiting the bag and mixing with outside air. As Link squeezed the bag more gas came out and the flame kept going until the bag was fully emptied. You could scale this system up to power a small gas engine, lawn mower, generator, tractor or even a car. Many such systems have been built in the past and are still running today. The wood gas must be filtered before you run it into an engine in order to prevent gumming up the internal parts of the engine. I do plan to build a wood gas generator myself next year. This demonstration only fuels my ideas. Thank you Link for the fine demonstration.
