Incineration is popular in countries like Japan where land is scarce and many European countries are recovering heat and electricity by incinerating their waste.  A BSP multiple hearth furnace can convert virtually any combination of waste sludge or sized solids into ash, at less than 5% of its original volume. In addition, the volatiles within the sludge can provide enough energy to eliminate the need for auxiliary fuel.

With the incineration process there are no leaching problems to predict, no potential bacterial breeding grounds, and concomitant noxious odors to control.  Instead, the end product is a dry, sterile, odor-free ash.  More than 99% of the ash is discharged as a dry, cooled product from the bottom hearth furnace. The few remaining entrained solids in the gas are captured in an efficient scrubbing system to assure virtually pollution-free exhaust.
Combustion of waste feeds such as:
  • Biological sludge
  • Chemical plant sludge
  • Pulp and paper mill sludge
  • Oil refinery sludge
  • Still bottoms
  • Spent filter air
  • Sized refuse
