   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.
