There is a guy here with one of those outdoor wood boilers connected to
his house heating system with underground forced hot water pipes. He
seems to be able to burn rather junky wood (pine, stumps, wood starting
to rot etc) but he uses some substance placed on wood which seems to
help it burn. Anyone know what it is? He doesn't, he gets it from the
place that sold him the boiler. Is it a catalyst?
It is no sort of fire accelerant, it is most likely something to help keep the creosote / crap from building up on the heat exchanger surfaces... anything from common salt to trisodium phosphate. You know the "creosote logs"?

MY guess. Just something that will not damage the heated boiler surfaces.
