Probably Corn Flakes from Cargill

No Sawdust at all in the new test fuel. I am keeping my mouth shut for now as I want to look further into some opportunities.

Its from Cargill but not corn flakes.

Now that you know where its from its a matter of finding out which product of the 30 they sell

I know one thing, this stuff is like nothing I have ever tried and if the price holds everyone would be able to have a Biomizer and save a fortune on propane or fuel oil.

Thought I would put up a pic of the controls as they are running on my PC tonight.

As you can see, the auger feed rate is only 9

The Ash number represents the number of minutes before it cylces on. When its on its only for 10 seconds. I may have to increase the cycle time since there is so little ash with this stuff.

Could I burn the material in my Taylors? Prsoblem is, we do not have that kind of material production, here on the Left Coast.

The first column is Combustion temp. I have my high limit set at 205 and the low at 194. When it hits the high it shuts off automatically then when it hits the low it turns on automatically.

The second column is the combustion temp. 1650 F is the max.

Third column is the ceramic temp. Once the ceramics are heated up they hold the heat for a very long time and also provide the ignition source on start up. If the ceramics are hot enough the unit never even calls for propane.

The last column is the flue temp. I would like to capture the flue heat as I think a lot is being wasted from that, even though this thing is pretty efficient.

Frank,
Not sure on if it would burn in the taylor. If it burns logs I doubt it would work very well. Needs to be a suspended burn. Kind of like throwing flour up in the air above a bon fire.

I had filled the hopper full last night and this morning we have dropped about 8 inches from the top.

Kirk Allen · « **Reply #206 on:** January 03, 2009, 04:30:39 PM »

What I failed to realize until checking the hopper a few minutes ago is that when I filled it last night the biomizer had been off for a day and the water temps were down to 100. It used a good portion of the 8" of fuel last night just getting the water up to 205.

When I checked it a minute ago I was baffled becasue it hasnt dropped more than 4 inches from where it was this morning, then it hit me. The water was up to temp and it only comes on for a very short time to keep within limits, thus very little fuel needed.

From what I see this afternoon I suspect this one hopper will last 3 days comfortably and maybe 4 days. I know it would if I turned down the water temp but our temps are suppose to drop like a rock tomarrow so I am going to leave it as is.

If that is the case, Kirk, I know the Taylor will burn pellets from a hopper system as well as the logs. So, I surmise that your product could burn in such a unit.

Kirk Allen · « **Reply #208 on:** January 03, 2009, 07:38:18 PM »

I suspect so but I know some of the corn burners that can burn pellats cant burn fine dust material because of the blower in the hot box. Not sure how the Taylor works but I know plenty of truckers that would bring you about 45,000lbs

$300 credit on the taxes for a Biomass stove! I can add this to my total savings!

I've run propane converted trucks, off road, in Wyoming in the winter.

The converter/demand valve on the conversion kit is plumbed into the cooling system to provide heat to the converter to prevent freeze up. It's purpose was to convert liquid propane to vapor

The fuel tank had a vapor valve and a liquid valve. You'd start on vapor and had to switch to liquid to get enough power to run the truck engine under load. Idle of high idle was ok either way.

If you didn't start on vapor and warm the engine up a bit the expansion of the liquid propane would freeze the coolant at the converter and make the biggest icecube under the hood of the truck you've every seen.

Are you running vapor or liquid to the valve? That might be your problem. Expanding propane can get -60F, fast.

Also was told it would get so cold in Scoby, MT that the restaurant had to build a fire under their propane tank to get enough gas pressure to have the cook stove work. Now that's scarey! Propane looses a lot of pressure when it gets cold.

The unit uses vapor. Turns out the problem lied within the nozzle port. It was suppose to be a tight fit at the face of the inginiter assembly. The flange was slightly bent and allowing air to get in and causing the problem.

After finding it we are working perfectly as far as the starting problem goes. Still some Ash Stir issues we are working on but the unit is running awesome. 36 hours since the last hopper fill and this morning there is still over half a hopper full. That means I could possibly get 72 hours on one hopper!

Why is that such a big deal? How many OWB (Outdoor Wood Boiler) folks have to fill it with fire wood every 12 hours? Only having to fill this thing once a day was a plus but imagine only every 2-3 days

Suppose it would burn saw dust from a Lucas or MD?

Kirk Allen · « **Reply #213 on:** January 09, 2009, 10:09:49 PM »

I am sure it would!

Kirk Allen · « **Reply #214 on:** January 12, 2009, 05:05:00 PM »

We have managed to get 80 hours on one hopper of the super fuel. I am rather overwhelmed how well this stuff is working.

I have found that you need to have a feed rate that keeps the combustion temps in the 1400-1550 F range. When I kept the temps down around 1250 F I ended up with lots of clinkers. Upping the feed rate to get higher temps took care of that problem.

Right now we are running the auger at a rate of 10 with the air at 28 and have pretty consistant temps of 1475-1525 F.

It sure is nice to not have to worry about filling the hopper every morning or afternooon.

With the cold snap we have coming later in the week I hope to be able to fill the hopper on Thursday afternoon and not have to mess with it in the cold until Sunday night, when it warms up a few degrees

that wood be nice to only feed it 2 a week

Kirk Allen · « **Reply #216 on:** January 12, 2009, 08:26:30 PM »

Nice is an understatement Mike. Its a "relief"! As you know, stoking the burner every 12 hours gets old fast. Even though its free heat, it takes its toll the older we get.

mike p · « **Reply #217 on:** January 13, 2009, 09:16:04 PM »

yes our stove gets fed about every 5 hours

Frank Pender - AKA "Tail Gunner" · « **Reply #218 on:** January 16, 2009, 07:42:44 AM »

What are you talking about, Kirk? I feed mine twice a day and I am 20 years your senior. Get off if age excuse, my friend.

In fact, I feed two furnaces a day. One is all year long, for the kiln.

Kirk Allen · « **Reply #219 on:** January 16, 2009, 08:11:06 AM »

Let me clarify Frank

When I get "much" older, like 65

I don't want to have to cut and split wood. This is much simpler and easier on my body! Us young pups are not built the same as you old farts! You guys walked up hill both ways to school, chipped salt off the cattle's salt blocks for table salt and since your in Oregon, your heritage was built of steel, as mine only made to the midwest

You left out a couple: I used raw milassis on my pancakes and wrestled my cattle without a rope, for doctoring.

Stevem · « **Reply #221 on:** January 16, 2009, 11:36:16 PM »

And didn't put his shoes on 'till he got to school, so they'ed last all year.

Cmon Kirk,

Frank is one of the 'softer' ones here

BTW you should see a pic of his cowboy hat on top of the tinsel one

Frank Pender - AKA "Tail Gunner" · « **Reply #223 on:** January 17, 2009, 09:42:00 AM »

Geeeeee, I got three good friends,out there in syber land. Harry, where are you to make number 4?

Kirk Allen · « **Reply #224 on:** January 17, 2009, 01:25:55 PM »

If its one of Franks pics we will never see it
