Summer projects

It looks like winter is almost over, and the wood boiler did a great job keeping us warm and supplying all the hot water we could use.  I am working on getting a full set of plans made so it will be easy for anyone to make a high quality wood gasifier boiler, and I have already started getting wood for next winter (I want to let it dry out all summer).

Now that the boiler is done, it is time to move on to some other projects.  Here is what I plan to get done this summer:

1- Build some hot water solar panels to heat hot water during the summer (so I don't need to use the wood boiler all summer)
2- Convert a Honda passport over to run on electricity
3- Build a carport to park, and also charge the electirc car  (this will also be used to mount the extra solar panels (see #4)
4- scale up my solar panel arrar you be able to produce enough power to run my electric car
5- Setup an inverter to run off my electirc cars batery bank to power my house during power outages (my car will store 40kwh of power)

I have a feeling this is going to be a busy summer….

Low Power bills

I think rocky mountain power is confused as to why my power bill is so low this winter.

First live run

I just ran my first live run with my wood boiler, and it is working great. I was able to heat up my house (it actually got too hot, because it is not very cold). And I was able to heat my hot water tank. Also my automated controls worked flawlessly turning the burn on and off as needed, to keep the water temperature perfect, and making the wood last longer. I even shut the boiler down for about 15 hours, and it was able to fire up on its own without lighting it. I have made a couple videos. This one shows the burn and the boiler This explains the secondary air injection.

Wood shed and burn test

Building a wood shedI spent today working on a wood shed to keep my wood nice and dry for my wood boiler.

I also did some more test burns with the wood boiler, and think I finally have it working really well.

Primary burn chamberAfter a bunch of testing, I think I finally know what to do to get the primary, and secondary burn to work well.  I will just need to get a second blower to getenough air to both of them.  I have increased the flow to the primary burn chamber, but now the blower does not put out enough air to secondary burn chamber (the blower I am using just does not have the capacity.  You can see my video here

Secondary air injection

Air injection box IMG_0050 IMG_0051I added a secondary air injection box to pre-heat the secondary air before it is injected…

Some more testing

Screenshot from 2013-04-18 21:05:59 Screenshot from 2013-04-18 21:03:23I did some more testing today.  The fire is very easy to start, and the secondary burn is fireing up quickly,  However I still need to get more air into the secondary burn  I plan on working on that some more this weekend, and getting more firebricks setup in the secondary burn area.

New video with fire brick, and exhaust manifold description

starting fireI have enstalled firebrick, in the primary burn chamber, and plumbed air into the secondary burn.  I didn't have any dry wood, and run out of time to get the secondary burn going.  However this video describes my setup.

Hopefully I will get more time this week to give it a better test.

We have fire

snapshot1After a few modifications, the secondary burn is really burning!!

I had to increse my exhast pipes to 3, and got the fire buring hot before closing the door.  It lit up right away, and burned great until I turned it off when the water in my tank was steaming hot (about 20-30 minutes to heat up 200 gallons of water).

Another test burn

Doing some more testing.  I think I need to open up my exhaust into my secondary burn area.  The fire litup very easily, and burned great until I shut the door to force it through the secondary burn chamber.

Here is a video of the whole thing, including an explination of some changes I have made.
