Hi every body
I want to fix the system today
Before I started, I wanted to ask you a comment
1-Close the firetube
2-Air nozzles,about 15cm from the bottom of the firretube
3-steel ring in the firetube
4-Lowering the height of the gas outlet pipe
5-Fill with fine charcoal up to air nozzles
6-i use Dimmer for control my fan speed
Thank you so much
You will need to place the charcoal inside, then light through air nozzle.
I did not know you had nozzles so I will let other help from here on. They will be better at this design.
The ring can come up higher, lets say somewhere in between the nozzles and firetube bottom. 7cm lower thain the nozzles. The gas outlet doesent need changeing.
You just fill the system with bean size charcoal and light trugh one air nozzle.
I think it would be more difficult to raise the ring Kristjan. I am sure there are plenty of rings that are on the bottom. An ash cone will build up around the ring and protect that portion of the fire tube. This way he has more charcoal for gas conversion available.
If the ring (restriction) is the same diameter as the id of the firetube it can be moved up and down easyaly.
The restriction that low wuld make the oxy zone much too big (15cm high) and the reduction much too small (3cm) for good clean gas production.
My first gasifier I ran with wood chips was a 10cm fire tube with 8- 6mm air jets that were 20cm from a fixed grate. It ran a 13hp Honda just fine with no tar buildup in my engine. I started out like Saman here with the only difference of having preheated air jets.
Befor you change you system try Mr. Wayne suggestion. If you can’t get a flammable gas, the you can make physical changes as Kristijan is recommending. Check your vacuum. TomC
No restriction? Well l guess good preheat might made it somewhat similar to wk design.
I stand corrected. I just found a drawing of my first gasifier.
Exactly. Be sure to report your sucess!
Kristijan, he needs a grate, yes?
Yes, sure, he shows the grate on all top skeches and most likely forgot about it here.
Yes i forgot to draw a grate.
I hope he doesn’t forget to let us know what happened.
Coming from the dark side of gasification, this conversation really helped clarify my understanding of how a small and basic wood gasser woks. I too hope to hear good news from Saman.
I do not remember, I’m sure.
I’m a member of this group from now
I hope that I will be useful
I repaired my gasifier
I am very glad. I’ve had good progress with your help
Thank you all
I completely ignited the charcoal. Then I added the pellets
The device worked after 30 seconds and the gas ignited
But after a few seconds it did not work anymore
I think I have 2 problems
