Gasifier the hive

[d100f]

I use a very large gasifier tank a 205 litre drum with a vertical nozzle from below and i suffer from harder than normal starting once fresh charcoal has been run once , what i found best for quicker lighting was to do what the wood gassers do and before lighting poke through the charcoal around the nozzle area and break up some of the charcoal and clinkers that are around the area of the nozzle , and i also poke a allthread bar up through the nozzle as well , and i find that helps a lot to get fresher charcoal reacting .

Thierry,
Congratulations! We look forward to hearing how other tweaks (water drip, EGR, timing advance and increasing nozzle size) affect your system performance.

On the issue of starting up with used charcoal, poking through my nozzle is usually enough. If I want to be sure, I use a small screw type earth anchor to spiral down to the bottom and lift the old charcoal away from the nozzle then I use Kristijan’s pointed and perforated vacuum nozzle to suck out ash and dust from the loosened charcoal. Although I haven’t tried this yet, it has been reported that using your blower/fan to suck some fresh little pieces through your nozzle will do the trick.

I temporarily installed a pipe and an adjustment valve and everything worked. I need to install a new adjustment valve upstream of the flowmeter so that it can, again, run on gasoline or chargas or in hybrid mode .

although I sealed the air line as well as possible
I can not adjust the air / gas ratio with my butterfly valve cituated upstream of
flowmeter.
Do you believe that the hose that comes from the resonator and between the air filter and the flowmeter could de-adjust the valve

Thierry,
Any hose bypassing your valve will offset the air-mix. Try see to that your valve has the same conditions as your flowmeter.

Has anyone ever tried this kind of pressure sensor to measure the differential pressure of gas and air at the mixer?

the sensitivity of this kind of probe is it accurate enough to manually adjust the air restriction valve?

Hi
I am looking for information to build a safety filter to complete the gasification plant on my truck. I read that wire cloth filters were recommended. Does anyone have information on this subject?

Thierry

[trigaux]

I had recovered this some time ago at the scrap yard. I think to use this support to hold a filtering metal mesh
I want to use an anti kitchen splash like this one as a safety filter (16 pin per inch)

Do you think that setup will work?

Thierry

Thierry,
Looks like a beautiful solution to me, just make it fairly easy to inspect, and well-sealed from outside air.

[bsoutherland]

Most guys just trust their regular paper air filter. The metal screen safety filters that I have read about recommend 25 micron or 400 mesh. I think about 100 square inches would be adequate, but have a replacement filter ready since cleaning the fine filter screen can take some time and effort.

thanks for the information Bruce

Hello everyone

I built this automixer for my truck.
I think it’s different from other automixers.
the transfer of the movement does this by a hinge in place of the longitudinal displacement of an axis
this design facilitates sealing and minimizes mechanical losses caused by friction

What do you think?

Sounds interesting…
The video link doesn’t work.

[trigaux]

Try again, I fixed it!

[Terry_Lavictoire]

Excellent solution!
That should make things a lot easier.

[bsoutherland]

Hi Thierry,

Thanks for sharing the idea and video, but I don’t understand what I’m looking at. How about a sketch? I can imagine a hinge fastened to the diaphragm, but don’t understand how you are sealing the output rod.

[trigaux]

Excuse me time for the answer, I am very busy at this time of the year
Bruse here is what I use to seal

Another advantage of this automixer design is that it can also work horizontally

[bsoutherland]

Thank you for taking the time to answer. Very Clever.

Hello everyone

I would like to replace my big 5 "cyclone with two small cyclones in parallel.
Or can I find the information to size cyclones of equivalent efficiency?
Thank , Thierry

[KristijanL]

I think l used 2 4" cyclones on my mb, worked well. Oh, that was paralell!

[abreaks]

Dyson uses a huge array of smaller cyclones in their vacuums. They take their engineering pretty seriously so I don’t think the cyclone arrangement is an accident.

The motivation could be more compact packaging but I think it has more to do with smaller cyclones having higher accelerations to help with separation efficiency. Now that I think about it… I’m sure there is plenty of academic literature on the subject.
