Made easy - the mechanical way


  • Metso submerged chain conveyors are designed on rollers to allow easy access to the boiler
  • Moves material approximately 8 to 12 feet per minute
  • Has up to a 35 degree incline which allows excess water to drain from material


  • Reduced capital costs
  • Less space-consuming equipment
  • Lower power consumption
  • Less maintenance requirements
  • Lower water consumption

How it works

Bottom ash is continually collected, cooled and dewatered with a submerged chain conveyor. Ash falls constantly from the boiler through a discharge hopper into a water filled chamber where the continuous-loop, dual-strand submerged chain conveyor cools it and transports it for disposal.  The inclined section allows excess water to be drained from the ash material.
