Thanks for the reply. The size of the pellets was a thought of mine also, but being so new to this i thought it best to ask the experts. I also wanted to say you have the most amazing ideas in gasification. You must never sleep.
Welcome Darrell. Very nice build. I am always interested in ways that the average person can produce useable gas and I have been recently thinking about building one of Matts ammo box units. Now I know Iâm going to.
Success!! This clean out / grate chamber I think will be the most difficult part of the new machines to produce. Other than some fine tuning I need to make it worked. I just need to enlarge the can shell to fit the flanges a little better. This first one was a bit loose and then the door could be rolled a little tighter. The door needs to be slight under rolled for a proper seal as we learned to do this before. But this makes for a better sealing door system as it sort works like a hose clamp when you pull the latch tight.
I didnât get much sleep, and I just looked at the pictures, and I was like wtf. Is that supposed to be forge burner or a kiln?
Ash bin for the new model.
Welcome Darrrell , thatâs a great build you did there , if i can suggest while you are waiting for the parts on your gen why donât you play a little try mixing in a small % of wood chips or pellets in with your charcoal see how your filter material fairs up if you have made any tars your filter will soon tell you how its doing . you have lots more fun to come
Dave
Thatâs a good idea. It is a 81mm ammo can. I have a 60mm ammo can Iâm going to make a filter. Iâm already reworking the nozzle as per Mattâs new design. My plan is to play with this then order Mattâs weld kit for the DFX-10.
Darn it! I really wanted to do a vidoe to show how to fix a tared up generator. But unfortunatly todays 100% wood gas run was total success. So I guess that video will have to wait another day
Hopper agitator did the trick ran very stable and no bridging issues. I fixed the ammo box and welded in expanded metal so that issue is now put to rest. Very happy with todays run this machine is the way forward cant wait to test the production version it should do even better!!
Ok there it is;; a Gasifier in a can. This is the DXF-10; the reactor is packed inside the hopper. Only thing I cant fit are the legs. This is the base version, wheel kits, automation, the filter system, hose/ammo box/ engine kit will all be sold sepperatly. RTR versions will just be a packaged deal that includes a complete package but everything but will still be individually shipped items. Additional automation will be offered as add ons like the grate agitator and Electronic Mixer controller will come in a simplified form. Along with the kiln that will no longer be free. That is also get revised here soon.
So in 3 days I recieved the parts and built it ready ship; if it were actually shipping somewhere. Not bad plus I worked in production on top of it.
Tomorrow will be a staged unboxing thing to show how to put it together and outside it goes for testing
EEEeeewwwwhhh I got tar in my engine!!! LOL. Yeah cooked the filter media it wasnt the gasifier. The DXF-10 is 1 inch larger than the proto so it has 1 inch thicker insulation. I think instead of gas shedding heat at the gasifier its carrying the heat out causing the gas to be hotter at the filter. Yeah even burnt the paint off the side of barrel drum and the hay pretty much all charcoal.
I did make a change to the gasfier today though and cut out about 40% of the lower insulation section giving some expantion like the proto has. This I think loosen things up at the grate plus increasing the reduction capacity. So I think its a good trade off. This lower chamber was an after thought as I was building the original; I think its partly why that machine worked so well.
Running good and strong today though.
im looking ate the DXF-1- HF build vid. I have a 2x6 bell reducer .25 in thick i was thinking of using. Does this go in the combustion chamber or upside down in the reduction zone?
In installs in combustion chamber sort of like a funnel.
Unlocking the secrets of the HF gasifier.
Ok guys another thing I changed on this pre production DXF-10 from the Proto is I adjusted the Jet nozzle coupling fittings to center the oxidation zone. I think now that maybe a misake and I may have stumbled on a new type of reactor. I think there is something to having having less oxidation from the back to the front. The back I think is preconditioning the fuel along with pyrolisis stage where the primary can then better process both fuel and the pyrolysis gas. To add I think stepping these jets apart may benifit. Where the secodaries are now either angled upwards or placed higher and the the lower Primary is straight / angled down and placed lower. I know stepping jets is nothing new but here Im only stepping 1/3 of the jet ring for the secondary and there is only one larger jet at the front and no additional on either side. I think there maybe something to this.
So ordered parts today to rebuild the reactor. This is the âtwo stage eccentric reactorâ
As I aways say there is something new in the wood gasification world or it has been past forgotten and rediscovered.
Looking forward to this new nozzles arrangements.
Yeah that is the way very impressed with the 50/50 mix. Ran consistant and made good power.
So just pulled the trigger on the " Super Handy" wood chipper from Amazon. lol Weâll see how âhandyâ it is. haha.
Decided to try this one as the shoot should be high enough to spit the chips in a garbage can. The Harbor Frieght has a bag it spits them into and its really combersome. Plus I want to see if this one will produce better chips. The HF unit does not produce very uniform chips. Its either large pieces that bypass the blade or dust and not much in between.
I thought you could get buku amount of chips from that business in your back yard?
Got to pay for it
