Waste heat for a ceramic dryer is most often taken from

  • A.the glaze preparation department
  • B.the cooling zone of the kiln
  • C.the electricity supply to the plant
  • D.the raw material stockpile

Answer: B

Correct answer: the cooling zone of the kiln

Ware leaving the firing zone must be cooled, and the air used to cool it emerges hot and clean - exactly what a dryer needs. Ducting it to the dryer recovers heat that would otherwise be vented and is the single largest energy saving available in a ceramic works, which is why kiln and dryer are usually designed and sited as one system.
