  • so you should wait until the flames go out by themselves? i built one just early and it worked sweet, but i put the flames out myself. 

  • @nden85 You can put it out when the flames stop or slightly before.

  • @theoriginalSkooby thanks for the response. do you use water or suffocate it?

  • @nden85 I use water.

  • i made one from a 20 gallon oil drum and a 6'' stove pipe, but im getting a lot of smoke and i get no flame from the holes at the top of the stove pipe. do i need to vent more?

  • Do you have a lot of ventilation at the bottom? It is hard to say without seeing it. My larger barrel also doesn't run right unless I power feed air at the bottom. Check out my Biochar 2 video and see if it is doing the same thing.

  • That is NOT a gasifier. THAT is an overly elaborate and inefficient wood burning stove.

    Youtube search this:

    MAKING BIOCHAR: with Peter Hirst of New England Biochar

    THAT is a gasifier. THAT makes charcoal.

    I built a retort stove based on the Hirst design that uses an old water heater tank for the INNER drum. This makes about enough charcoal to fill two 5 gallon buckets per burn. And the charcoal is insanely light and crumbly.

    Don't youtube unless you have to.

  • @evifj or you could just get the ratio of holes right so there is a natural draft and skip the blower.

  • @WDW888 put a blower on the bottom to help push air thru the gasifier

  • Thanks for sharing, I set my microwave on fire drying chips. It has been two years and my wife will still will not let me live it down!

  • i am in the same situation as you, i can`t get flamable gas. can you help me? project it is in my videos
