This is the build of a simple Wood gas generator for small 5HP electric generator.This is made from simple materials that can be easily found around your home.
STEP 1 : THE SETUP
The main generator here is a 20 gallon garbage can. Inside I have a wine cooler and inside there I have hung a small steel bowl.
STEP 2 : CONNECTING THE FILTER
It’s just connected up to this very long aluminum duct line to my filter and my filter has been filled with wood pellets to also serve as the fuel.
.
STEP 3 : AIR INTAKE
Then the outlet line goes over to an air inlet port.When you burn the gas you have to add air and this is the valve I’ve designed to allow that.
It goes all the way to the RV Gas engine.You can cut off the fuel by using a wire to cut off the fuel pump.
We use a 20 gallon garbage can as the filter.So first I use a quarter inch drill to put two holes in here and then I’ve enlarged it with a nibbler.Put a harbour wire down in the can where the filter medium is dumped.
I use pine wood shavings as a filter medium.Use about 1/3 to fill up my 20 gallon.
STEP 4 : THE REACTOR
The reactor is basically constructed out of a stainless steel thermos, which is a central cylinder that is double walled and it has like a one inch opening at the bottom. And below that we’ve just hung a steel mixing bowl that we basically drilled a lot of holes into and then hung by these three chains that you have riveted in.
And then we just connected it with a simple 20 foot ordinary dryer duct.
The reactor is filled up some wood pellets ,we have stretched out the hose, this will cool the gas into the improved 20 gallon filter.
And I’m going to be driving this with a small air mattress pump. And what I’ve done is I’ve rigged myself a dimmer control here so I can actually control the speed.
