Do you already have the generator you want to run on woodgas? What is the displacement of the engine?
Also if you could manage to run through 250kg of wood in a day I would be very surprised. I believe with a Ben Peterson gasifier you get a few hours out of a hopper running a 500cc engine. The hopper load is maybe 20kg unless you expanded it.
joep actually I would produce pellets since the idea is to generate energy at a cost below 0.20 cents (here it costs 1.25 kWh) and pellets would not be viable since they cost around 2 reais per kg. They are not really used here, it is even difficult to find, believe it or not.
Cody, I chose to buy a 210cc stationary engine and an alternator. I’m not an expert in generators, so I imagine that engine maintenance would be easier and more practical to put a rectifier bridge on the alternator and transform it into direct current and connect it to a photovoltaic inverter.
O básico está ± funcionando vou enviar um link antes disso peço desculpas pela bagunça a cabeça borbulhando faltou tempo pra limpeza (nunca pensei em enviar vídeos pra ninguém rsrs)
Hi Caio, welcome to the forum. The Ben Peterson is the probably the best option if you want to use pellets. Here is some links for some charcoal gasifiers you may find helpful.
Gary Gilmore has designed a real nice and simple charcoal gasifier. The design is so simple it can be made from almost anything you have available.
Matt Ryder has made some really nice gasifiers made specifically for a generator setup. Most of those are charcoal also.
Let me just say I have no hands on experience with charcoal gasifier. Hope you find something useful in those threads.
bronlin thank you very much I am very happy to find the forum and see it active and working. I have been swallowing the information that has been repressed for years I think I will go crazy before everything happens lol. I will take a look there. I have already found Matt Ryder on YouTube I sent an email and he was receptive. Maybe the easiest way would be to transform the chips that I have available into charcoal in the barrel as in the video above to start raising money for books and equipment. Here things are more complicated (from what I saw books that cost a few hours of your work at the convention become almost two weeks here) but no problem. By putting it to work I transform waste into money (I will connect it to the on grid network and transform it into energy credit) I do not know if it is like that there but here I inject energy into the network with photovoltaic panels or biomass or hydroelectric and it returns to another meter that I prefer in credits. That would be the main idea. A big hug thanks for answering
Caio,
Welcome to the forum. From your videos it looks like you are well on your way to success. Keep up the good work. If books are unaffordable, there are many gasifier books available as free pdf downloads on-line, including from this website. Thanks for posting your work.
Steve, thanks for the comment. It seems like I’ve just been born crazy, even when I thought I had a minimum of knowledge, I come across thousands of gasifiers, fuel diameters, temperature equations, melting nozzles, etc. But great, I believe I’ll get a lot out of you and in the near future I’ll be able to contribute too.
Welcome here Caio.
In the library section there are many publications about gasification to read.
As Steve said, by the looks on the videos you are already on your way and understand the processes. Keep it up and good luck 
Caio, forget making pellets. Dont believe everything you see on YT. Very difficult and you need serious equipment, at least a 7,5 kW press, augers, dryers etc, to make a continuous flow of pellets. Been there, done that. And then you still dont produce any woodgas.
Nice puctures! Looks like a Koen gasifier and a Hookway retort. Looking good!
Tone mentioned capacitors. I am waiting for them and want to use a three phase motor , rectifier and solar inverter. I think a car alternator has a bad efficiency.
My experimental setup is grid tied, standard three phase running 3050 rpm. Works great.
Hello Ciao, I would like to mention only a few features that apply to the conversion of wood into clean gas:
-larger pieces of wood turn into gas more slowly than smaller ones
if we use small wood chips or sawdust as raw material for gas, it is necessary to ensure that enough charcoal is produced higher up and that it does not burn there
, that the inside of the gasifier is of the same diameter, that there is no fuel bridging
, so that the flow of gases weakens below - it raises the mixture of fine coal and ash and thus withdraws the ash from the process

Welcome to the site Ciao. Here is a post a while ago by Eddie Ramos. Here is from Argentina and has driven all over southern South America. If you could contact him you would get a lot of valuable information in your native tongue. I couldn’t find a link to his youtube channel,
Johan, I’m taking a look around there. I like to read and execute projects. I’m a fan of “knowledge doesn’t take up space”. Joe, I’ll do that. I’ll start with coal, it’s definitely the easiest way to deal with it at the beginning. Tom, I have to understand the project better. I did it and it worked, but I don’t know to what extent. Now I know I had a problem with the bridge, but one day at a time.
Tom Thank you very much I will find him
Caio,
Welcome! Eddie Ramos does most of his communications on the Auto A Basura group on Facebook. here is a basic link to that page.

He is very genuine about sharing the knowledge about gasification.
@Matt as well as a few others, have tried whole systems similar to what you are proposing. There are 3 issues. The pellets themselves have binders that are additives and can cause issues. The power output of woodgas is <40% of rated power on gas, and single cylinder engines don’t create continuous air flow which causes issues in the combustion chamber.
Eventually Matt changed to coal and dual generators.
It sawdust works much better at a much larger, industrial scale.
Honestly, if you are looking for grid power, then you are probably better off installing solar panels and using the sawdust to improve your soil nutrients. Solar is a lot less work, but also more expensive to start.
Yeah you need solar first. You need an inverter with battery storage reguardless for any wood gasifier of any kind made by anyone to be practical and viable. This is only a good solution for solar and wind back up. Its not a reliable technology for everyday usage and you need a battery storage system.
Running a stationary wood gassed power generator as a primary power solution is the last thing you will ever want to do. After about a week you will throw that gasifier in the landfill and resort back to candles.
Dont waste one second more of your life thinking about or designing a wood gasifer of anykind for small engines. Its a waste of your time, your money and your sanity. Stop and start learning about charcoal gasifier. Reguardless you will end up here in the end. So do it now and forget wood fueled systems and wasting all that time, money and energy. Charcoal is the only way to run small engines under 1000cc reliably and making charcoal is not less efficient. If you have an efficient retort and a gasifier that can crack a lot of water the gross energy in versus out is about the same. What you lose in charcoaling the water cracking puts back. Plus you and use that charcoal retort for heating and hot water production. You can make charcoal into a CHP system far easer than a wood gasifier system.
Mike I’ll stop by, thanks. Sean is a mix of DIY and initial savings. I have plans to install more solar panels but I would really like to do it with wood gas/coal, I think it’s fantastic and I’m not limited to the sun for a few hours. Sorry for the delay in responding, it seems I was too quick and was blocked from responding.
Matt, I have solar energy (I installed it myself. I like to get my hands dirty). The system here in Brazil is distributed generation. I’ll explain better. You get approval from the electricity company for generation, whether it’s solar (much simpler) or biomass or hydraulic, of any power up to 75 kW peak. You spend part of it in your home or business, and the rest you can use in any meter or meters from the same company in your city or neighboring cities. I don’t have batteries; the grid itself serves as one. I’m very inclined to coal, I know it’s easier. I did an updraft (video above). I’m studying to improve and understand the practice of all this. I haven’t used water yet. I did coal too. I have to fix leaks.
