A quadruple effect evaporator is fed 1 tonne of steam per hour. Roughly how much water can it evaporate?

  • A.about 1 tonne per hour
  • B.about 0.25 tonnes per hour
  • C.about 16 tonnes per hour
  • D.about 4 tonnes per hour

Answer: D

Each effect reuses the vapour of the one before, so the steam economy is roughly the number of effects. Losses and boiling point rise make the real figure a little lower than the ideal one. Steam economy is the figure a mill actually quotes.
