To date they have had almost 300 inquiries regarding this and the guy I just spoke with at WM said he is as eager to get the status on it as everyone else.
They are going to send out questionaires and maybe make phne calls etc. to select folks about their intended usage etc.
I hope it turns out to be as good as it sounds. Sawdust isn't hard to come by around here.
I wonder if the pulpwood market could get eclipsed by the sawdust market once enough of them are out in the field.
That sounds like a joke because the pulpwood market is so huge but what if this thing is so effecient that it rivals current home heating technology? I could see Sawdust Wagons replacing oil trucks in neighborhoods.

It would help raise pulp prices if that turned out to be the case.

yeah but what would it do to lemonade and flounder. And the ozone.

I just don't see it getting all that big.
I can see folks that have easy access to sawdust jumping on the band wagon, but there are already uses for sawdust and I think it will just drive the cost of obtaining sawdust up.

Wasn't there a sawdust burner that you could make out of a couple of 55 gal oil drums? I remember them back a number of years ago.

We can't get enough sawdust arond here for bedding now. Some is alreading being burned to heat the mill buildings and such. Unalam is burning their own shavings to heat the plant.
Dust from small bandsaws is not very good for bedding as it is too fine, so a burner will be a good use for that.

I'm curious how they intend to keep fresh, wet, sawdust from freezing up before burning. I would think it would be an issue for us potential northern customers.

I am one of those that are waiting to hear details. I would love to set one next to the Taylor that heats the house, hot water, and kiln.

I don't have alot of problems with sawdust freezing. My guess is that some of the moisture is removed in the blower system, either that or it is quick frozen and stays that way?

I already collect my sawdust in a gravity bed wagon, some goes to horse people, alot just goes to the burn pile or on trails in the woods.

waiting patiently..................sortof..........

I don't mean to hijack the thread, I'm anxious to hear about the WM burner too, but there is a sawdust burner on the market now for those who can't wait. It plugs into existing boilers. The one I saw referenced some years back was attached to a Taylor Outdoor boiler.

I see a big chipper feeding a large hopper eating all those pesky slabs coming off the mill. I could sell all my firewood to pay for it all. Have any idea what that auger system sells for? Joe

i just got a email from burnchips.the dragon is no longer made or sold.he didn,t tell me why..to bad it looked just like something i needed.
i wonder if a guy could make his own?? it don,t really look like it would be hard to do.
i,de like to build my own outdoor wood boiler and have it built right from the start with that dragon style hopper as part of it.

I too am anxious to hear more about the WM sawdust burner. Price and payback will be the big deciding factors for a lot of people.

woodmizer called me yesterday about the saw dust burners .they are getting info from potential costumers on what they will be heating: buildings, kilns etc. They said looks like they have 4 sizes available. I told them that I was concerned about frozen sawdust they said they only thing they are concerned about is the sawdust freezing in the auger. Sounds like they have a couple of different ways to combat that problem. It's gonna depend on your location. Only the largest size is gonna be able to burn sawdust, corn, pellets, wood chips, this unit is 1.5 million BTU. The smaller units will only burn the powder dust so if I want to burn my slab wood it has to be ground into a fine dust like a bandsaw produces. These will be duel fuel units. The ignition system will be propane fired for 5-10 minutes then the sawdust will be a perpetual burn. If you wanna leave the house for a weekend it has the propane burner is just as many BTU output as the sawdust burner itself so it can switch to propane if you are gone. They are also looking at generating small amounts of electricty with these units. Hope I got the information right this is as close as I can remember.

Are the WM units heating air like a forced air furnace or heating water like an outdoor boiler?

wood-mizer will be having a small scale sawdust burner with them for there 25th anniversary tour

I visited a sawmill this summer that had their own sawdust burning boiler/generator. 160KW generator that burned only sawdust, the larger stuff shook out to be ground up or sold. The whole setup was in it's own building and computer controlled. As big as it was, I assumed they needed a dedicated operator, but the boss only checked on it a couple times a day. They said it paid for itself in nothing flat, still didn't cover all their power requirements and they were looking to put in a bigger one. The only problem they had was their former customers were upset they weren't getting the sawdust anymore.

The surprising thing to me was how little sawdust it seemed to be burning. I figured the conveyor feed would be running continuously, but it started up and ran for a couple minutes and then would shut down for about 5 minutes. Might have been burning a couple of buckets of sawdust every ten minutes.

Riles,

You do not happen to remember who made the system do you? Sounds like a neat setup, heat and electricity too.

Oops, sorry about the bum steer.

If they are not selling it anymore you think they would update their website.

I was looking at that too.

Farmerdoug, I don't remember the name, but it was industrial sized, not what you would expect to see on your typical farm. The firebox alone was probably 8 x 8 and the building the whole thing was in might have been 30 x 30.
