Anyone know if it is safe to operate a rocket mass heater in a workshop where power tools will be creating sawdust? At normal levels of sawdust created by table saws, skill saws, etc, is there risk of an explosion? Other safety concerns? Thanks.
I done have the math answer of the density of sawdust that will ignite but I can tell you if it is dense enough to ignite, you are going to have one hell of a lung problem when you get older.
In other words, you shouldn't be letting your woodshop get that dusty as that is a killer, wooddust at that level definitely can cause health problems even if you are just using pine and domestic hardwoods.
Seems as though it should be ok, lots of shops are heated with plain woodstoves that have an open flame and significant surface temps. Spray would be a out of the question on a concurrent basis, but then an advantage of an RMH is you can get a lot heat out of the unit when the fire has burned out. I would like an RMH for my shop, and the biggest issue I have is that my shop doesn't need a sofa, so a design that is more workbench shaped would be more to my liking.
My three barrel tower was operated in my old workshop while running a stationary circular saw, bandsaw or planer. I used a dust extractor though like Max is doing. No explosions occured, only scorching of dust on top when the thing was run for the first time in autumn. Oh, by the way, I started my career as an apprentice in a carpentry shop with no dust extractor and small cast iron stoves for heating only, never experienced a dust explosion. Darn cold in winter I have to add...

Thanks! Guess I'll go ahead with this project then.
