search burn rate or flame speed , all gases have a max speed they can burn in feet per second, if its comeing out of the blower too fast it will go out, you can use a fan speed controler for a celeing fan to slow that blower.
As has already been said in the comments on a previous video, you really need to try fitting a proper flare to your outlet. I would be quite surprised if that does not sort out the "blowing out" of your flame.
Finally you should to adjust t the amount of inlet air betwen 28 and 33% respec to stoichiometric, using a valve or a frequency converter The estequimetric cuantity is 4,6 m3 of air/kg of biomass, so the cuantuty of air that should go into the combustion zone is from 1,29 to 1,61 m3 of air/kg of biomass. If you can regulate the amount of incoming air will surely get a gas with a heating value adequate to ignite the flame. You might even built a cleaning system and power generation in an engine.
Like you said, I think there are to much air, you could measure the air velocity in the inlet pipe by means of an anemeter or a rotameterand calculate the air flow (air flow = area of inlet pipe x air velocity) , also you need measure the biomass flow (in a short test of one or two hours you can calculate the biomass consumed in kg/h subtracting the initial and final weight divided by the time).
You can help by using condensation to remove water moister from the gas, and that will make the flame more self sustaining.
Thanks guys!! well done!
Are you guys going to make more videos for us all on TH-cam ??? Thanks
It's blowing itself out!
use a dimmer switch in line with your power supply to slow down your fan.
pretty orange flame there... you are still making tar there i think
Do you sell or share drawings? congratulations!
Funny that the title says( tar Free) en the only thing i see if a flame ful of tar 😅

we need to clean the air from them or not . Can we bring gas to engine directly.
the blower to much high you need fan control so the fire will stay !!!
