burning particle board sawdust in a rocket

Does anyone have any info on health risks of burning the sawdust from particle board in a rocket? I know there is glue that holds the board together and I want to know how badly I should look for a clean source of sawdust if I am going to try to heat with sawdust. I have a freind who says his sawsust is about 80/20 hardwood/particle board which is better thsan burning straight particle board dust, but I could look harder for a shop that only mills hardwood so I don't have to worry about chemicals in the glue.

Look for cabinet shops in the area as well. I get HUGE bags of sawdust from them every few months.

I would be interested in you idea and plan as well.

This is what I had in mind...

Bump for more info.

I was thinking the same thing as I have an endless supply of sawdust available.

Another video.



I think it looks like it burns kind of like a rocket (burning out it's riser every time). May be the perfect thing for a night stove in a greenhouse.

But could it be made as a true rocket? Could you make it to draw down through the sawdust and then into a rocket and riser or would your riser have to be stupid tall to have a chance for it to work?

Interesting idea, as we have a lot of saw mills local to me. Instead of buring the actual sawdust, could you make them into biofuel "logs" to burn in a rocket stove? I was actually looking at this concept the other night on www.home.fuse.net/engineering under their Easy BioMold − Your Choice document. Straight sawdust would be easier, if you could get it to work, eliminating the extra step of making the "logs".

This is an interesting idea and I like the clean-tech aspect. But is it a good idea to burn particle board? As much as I wish it were possible, plastics (including resins/glues/coatings, containers, bags, coated cardboard, etc) shouldn't be burned in a home-made situation. Go read about dioxins and scrubbers for a while and see if you still think it's a good idea. Leave that sh*t for a regulated/inspected incinerator. Instead, plant some trees and get coppicing! And buy real wood furniture so there's less of a market for wood products like particle board. Or somehow create a market for the sawdust before it can be made into particle board. Lots of good options that don't involve burning the stuff near your house!

K, good point. I missed the particle board part of the OP. I was thinking of plain old sawmill sawdust.

Jen, I have looked at the bio logs and they are good for using biomass in a normal wood oven--but they are kind of a PITA to make unless you have slave labor to do it. Even with the engineers without borders press (probably the fastest human-powered method there is) it takes a lot of time.
