Now that would be fun to check out. 8)

Woodmizer said today that their largest sawdust burner will be about 1 million BTUs.  It will burn any biomass like corn, small chips, sawdust, cardboard, hay, cornstalks even food waste.  They are working on a second phase that involves the processing of the biomass to burner size ie. a grinder of some kind too.  The thrid phase will be a generator.

The boiler is planned to be coming out this fall.  They will be sending a brochure out in about three weeks to people that have shown interest in the boiler.

Doug,

We had a similar conversation with Scott Laskowski a couple days ago. After the phone call, Linda and I were talking about the 1 million BTU burner. Here in Iowa, the DNR regulates all wood burners 1 million BTU's and bigger. However, Wisconsin does not start regulating until 5 million. So, it looks like each state law will have to be looked at. In Iowa an owner will have to obtain a permit and pay a fee to make a million BTU per hour.
Permits take a considerable amount of time to research and file. >:(
Did we mention a considerable amount of time. :o
That's a considerable amount of time for each permit  :-X

Now, there is a quick fix to this little problem. Reduce the sawdust auger RPM by 1%. WaLa 990,000 BTU's.
Add a label to the machine and avoid dealing with the government.

Or just build a 1.5 million and figure that any company big enough to use that many BTU's is already being visited by the DNR for water shed permits, storm water containment, fugitive dust permits, recycling programs, chemical spill plan, it goes on and on.

We did sent Scott Laskowski an Email in regard to Iowa DNR rules. He replied very quickly that he would be researching this issue further.  Wood Mizer has a lot riding on this project, and we are confident that they will develop and build a safe and efficient burner.

We have our name on the "I'll take one" list ;D

I defintly am interested in one too.  It just depends on the final price of it though.  I currently have the CB's largest outdoor boiler just under the pallet burner.  I love it but with each additional greenhouses it is losing the capacity to keep up with heat so instead of another CB I am thinking Woodmizer.  That would allow a whole different heat source material if  you know what I mean.  CB's do not burn cardboard and sawdust very good.

I gave a brief overview to a local tree service owner who wants to burn the chips he makes. He'll need the pulverizer that WM will make available during phase 2.

I kinda hope phase 2 happens quick because we'll use one for the trash under the sawmill.

Depending on what size unit you are getting I am sure you can get a hammermill that will size it to your needs.  They are available for just about anything.

Will the smaller units be the same as your normal pellet stoves?  Just burn loose sawdust instead of compressed?  Has anyone heard any prices mentioned?

Hasn't someone on here showed plans for a sawdust burner before using forced air to stir up the dust and cause it to burn hot?

I visited a sawmill this summer that had their own sawdust burning boiler/generator. 160KW generator that burned only sawdust,

Did you notice if they had to dry the sawdust first or could they use it straight from the mill?
A very wise man once told me . Grand children are great, we should have had them first

The sawdust, splinters, chips, stray bark, etc all moved by conveyor systems. Normally it fell into trailers and was sold to the OSB mill or the particleboard plant. Instead they sorted the bigger stuff out and dumped it into a pile in an open sided building and augured it into the boiler room. From the augur it fell onto a shaker conveyor which sorted out the sawdust that went into the boiler. The larger stuff went back around. I was told they could grind it, but had the impression they didn't do it because they didn't need to.

So to answer your question, no, they do not specifically dry it, although it's handled quite a bit and that may have some affect. The boiler did have forced air into the firebox but I don't think it was a "fluidized bed."

Here is a little more information.

 Bio-Mizer Biodust Burner


 
Pictured is the Domestic 150,000 btu/hr

*Can burn any suspended bio-dust
*Computer controlled with push button simplicity
*Fuel bin holds up to 3 day fuel supply
*Integrated fuel delivery system
*No clinkers (WM sawdust )
*Super clean emissions
*Hydronic heat system
*Air-to-air heat system
*Minimal ash buildup ( WM sawdust )
*Auto ash removal
*Environmentally friendly
*Doesn't "turn down" and smoke like stick burners do.
  This machine turns off when not needed, and reignites in seconds
  with the back up fuel system. Hot ignition virtually eliminates smoke on startup.




It is possible that the design of the Bio-Mizer may change some before it is for sale to the public.  But this gives every one a product update.

I had remembered this old post by Bibbyman and I made a lot of inquiries including Woodmiser,who informed me it was Don Laskowski's pet project.I e-mailed him and asked if there was any more development and I received from him(Don Laskowski) a very curt reply that he had no more involvement with the project.

It left me disatisfied with the lack of answers and I still would like to know what problems the Stirling had,was it a lame Duck or were there politics that ended the project. :-\

Doug,

We got it on Monday ;)



Riles and Paul,

Sunpower and Woodmizer have split up to put it nicely :-X

WM is working on a new system for the Bio-Mizer co gen. I have been told it's better technology than the Stirling engine :o

The Bio-Mizer web site is up.  Don't tell much we don't already know but if you're interested in keeping track of the developments, it'd be a site to mark in your favorites.

Anybody hear any price/availability details?

I thought I had a card from the guy who was at Perkinston with the Bio-Mizer, can't seem to find it.  I think he told me it would be in the $6,000 range, not sure but my feeble memory came up with that number from somewhere.  He did not give me a date of availability.

Hello to all,

Bioman is the new representative for Wood-Mizer.  We thought we'd jump in here to help answer questions related to the sawdust burner we are working on.   We're not here to sell (can't because it isn't ready yet). 

Since this is a forum, we thought this would be a great chance to hear from others on the realities and potential of the ways we can utilize biomass in a dust form.  We believe BioDust has the potential to become that 'new fuel' we've been looking for to make a dent in our dependency on oil on a global level. (There's nothing wrong with thinking 'big' is there?)  :)  I think you'll see what we mean as this thread progresses.....

To those who have researched sawdust burners I'd like to summarize what we've found and then respond to rebuttals.  Maybe we've missed something in our studies of the technology.

When you find a machine that burns sawdust it is typically large and expensive.  It also requires the dust to be relatively dry.  Sawdust will not be the best fuel for the unit - the unit is typically optimized for chips or some larger configuration.

Burn back, clinkers and host of other issues plague current technology when it comes to burning dust.

Most small scale versions simply don't work well or not at all.  If they can burn dust, it is not the optimal fuel. 

You can find drum or bucket smoker style burners but they are not going to solve the heating needs of a typical home today.  They smoke a lot.

There has been a lot of research done on developing small scale dust burners in all corners of the world - to date, we haven't seen or heard of a viable small scale unit that works well and/or falls in a decent price range.

If you do find a sawdust burner, almost without exception the sawdust has to be dry.  Wet sawdust is by nature hard to burn and smokes a lot.

All things considered ,if there was an answer to the list above, wouldn't the product already be on the market and obvious to us all?
