I have access to a steady supply of free pallets. I have not burned any through my boiler yet. I use them for stacking my cord wood on and burning in bonfires during the warmer season. I am going to cut a few up and try burning them through my boiler. Have any of you burned pallet wood through your gassification boilers? What do you use to "knock them down" or cut them up? I have seen some talk on Hearth about burning pallets. Some use special blades in there circ. saws, some use sawzalls, chain saws, etc. Suggestions? Any concerns for boiler? Metals, etc.?
