Spring Newsletter

It’s time for the Spring Wood Gas Newsletter… Hooray!

Welcome and thank you for taking a few minutes out of your day to stay updated on our favorite gas, WOOD GAS! I have some tutorials for you, new stuff & prize winner announcements.

First order of business

Yes! Blower motors are back in stock

I have made shipping free for everybody all over the world. You can order blowers in the builder area on the top right:

Next I want to share a tutorial video with you that explains why the blower is so important and all the suction sources I have used and experimented with so you don’t have to endure that yourself. Blower specs now in builder’s area.

Blower Tutorial

Combustion Tutorial

Here is a video discussing the inner workings and heat ranges inside your reactor’s hearth.

A Word About Gas Grading

There are basically two grades of gas you can make with your gasifier depending on your feedstock type and preparation.

Grade 1- Engine grade. This is a clean gas made from wood chunks and thick wood chips. Wood is ideal because of it’s low ash content. Wood breaks down from a solid, to oil vapors, to pure gas and small carbon molecules that are filtered before reaching the engine.

Grade 2- Heating grade. This is a more energy dense gas, but it has impurities that can foul an engine, like tar, a cooled oil vapor. Tar is no problem when you are just burning gas for heat. And you can use a wider range of feedstocks including chipped wood and some biomass. Chipped wood tends to stick together so be sure to have a stirring mechanism to keep it from clumping. Biomass is best gasified at lower temperatures to avoid fusing the silica into small stones called clinkers. To make this happen, you can use a slightly larger choke plate hole opening. Consider that tarry gas can foul your blower motor, so use a suction blower to start (10 min) and then switch to a push blower to maintain gas flow after start-up.

Wood Chunk Sizing to Engine Size

Your engine size will determine how much air passes over the charcoal in your gasifier. The more air there is, the faster it will eat up the charcoal, so with larger engines you can use larger wood chunks and with smaller engines you must use smaller wood chunks.

Wood sizing is also key in making the char reduce to a size that will pass through the opening in the choke plat in your hearth.

Rule of thumb for new users (newbies)

1″ sq./round chunks for 2 cylinder engines, kohler type

2″ sq./round chunks for 4 cylinder engines, generac type

2.5″ sq./round chunks for 8 cylinder engines, ford industrial genset type

For hardwoods you can reduce the size 15% because of the higher density.

Community Question

Which engine should I use when I get started making woodgas for stationary power?

Well, there is no one size fits all answer, but if it were me these would be my priorities:

  1. Spark ignited genset.  Gasoline, natural gas or propane.
  2. At least 2 cylinders, but I would definitely prefer a 4 cylinder engine. Plenty of suction to keep the gasifier hot, but not so big it will eat a ton of wood a day. The wood is free, but your time isn’t.
  3. How much power do you need? Take the genset rating and half it for woodgas, ex. 20kw natural gas to 10kw woodgas.
  4. Price. Don’t spend an arm and a leg. Get something good and used with low hours. You may dirty up your engine while you learn this woodgas thing, so start with something affordable and tough. Something that you can sell for the same price you bought it for.

Based on that and a quick search of ebay I found this listing:

woodgas genset

Hard to beat $3,000 for a good, solid, slow speed (quiet) water cooled genset. Just my 2 cents.

Woodgas Contest Prize Winners

My sincere apologies for taking so much time to get this announced. I was going to do it at Christmas time, but I was out of country volunteering and everything was on my big computer back home. When I came back I found my ex-wife was plotting shenanigans and walked into a shit storm of manufactured drama involving my kids that has side tracked me considerably. I bless and thank her for the work she did at Victory Gasworks back in the day, but enough is enough, let it go darling.

So with that out of the way I have finally found the time to add more stuff to the site, write a newsletter and announce these badass winners of free woodgas parts and advice! Thank you so much for being action takers, trail blazers and independent souls. The world needs you now more than ever.

DINK, Thanks for contacting me, but when I write back to your Yahoo address it bounces! I tried from several different accounts and no luck. This has happened before. Im not ignoring you. Do you have another email address perhaps? Thanks, Ben

Tech Support Update

If you didn’t get your book or need to renew a download link, please contact us. That being said…

After providing free tech support via email for the last 18 months, answering thousands of questions that are already answered in the Builder Area, FAQ, Wood Gas Crash Course, Free Report and the Wood Gasifier Builder’s Bible. I am informing everybody that I am not providing tech support any more. There is a solid body of work to get you going.

Most real world problems come from people going outside the specs of the book, using coal, small chips, tire chunks, etc. as feedstock or not using the specified blower and dealing with weak suction. If you want to trail blaze that’s awesome but you have to be your own guide.

Thank you for understanding. I am just too swamped with email and it slows everything down to answer questions that are already answered in our abundant free resources.

Thanks for reading

Cheers,

Ben Peterson
