Heat the Shop-Sawdust Stove

wow…I’ll have to build one of those for next winter!

Wonder how that would work, just hooking your dust collector up to it…lol

My Dad was really, really interested in building one of those sawdust stoves. The thing that really took him off of the idea was the thought that -God forbid- anything like a fire should ever happen, our homeowner’s insurance would probably not take kindly to a home-made stove. He probably would have made one if our shop was in some sort of an outbuilding, like a barn, but it’s attached to the house so- not going to happen.

But they’re a great idea otherwise!

In the winter e save or wood chops and shavings from the molder and shapers. This stuff gets burn in the wood stove. You wod not beleive the amount odf heat you can get out of this stuff.

You are correct that sawdust is explosive if added to enough moving air in its fine particle state with a source of ignition. Also, if in a pile where heat and moister would cause spontaneous combustion to occur.

However, you are limiting the air supply so as to control the explosive nature and it is compressed in very much the same way the commercially available blocks or log products are produced less the tons of pressure which would only reduces the efficiency BTU/lb recovery.

This type of stove was used during the depression at CC camps for heat and is used worldwide in some of the underdeveloped countries in a very much smaller size as a cooking stove.

I was thinking of scaling down the size because my shop does not generate that much sawdust and chips to use it as a primary source of heat, and recouping some benefit vs. just tossing it into the environment.

At present I am packing small paper bags and adding it to my wood stove, but feel that the efficiency would be increased greatly, more BTU/lb, if this type of stove was used.

I’ve seen where some LJs use egg crates, and then fill the egg holes with a mixture of sawdust and paraffin, using these as fire starters.

I would imagine that bigger versions of the same thing would make pretty good fuel for a wood-burning stove.

My dad works in a millwork shop and they generate a TON of sawdust every day. He brings a truckload to my cousin to use for bedding for the cows at his farm.

A couple of months ago I was looking into getting a pellet mill and making my own for a pellet boiler. A small mill will cost you a couple of grand and generate about 100lbs of pellets an hour.
