Allright! Looking realy good!
Feels good to see that flame for the first time no?
How do you seal the firetube to the gasifier shell?
Fix your airleaks! When air from a air leak meet the hot woodgas, it egnites in the gasifier, burning a part from the gas!
Allso, the gas seems steamy. Is your wood too moist?
You may get a lot better resaults with actual wood. Just cut a old wooden board or a pallet to about 1x1cm peaces and it shuld work good.
Allso, every gasifier needs time to set its self properly, so try burning it longer next time
