Question

List four consequences of losing 50% of condensate return, and for each, identify which link in the boiler circuit is affected.

Answer

Show answer

(a) Softener overload / hardness breakthrough → pretreatment link. (b) Cold deaerator / elevated dissolved oxygen → feedwater/deaeration link. (c) Low cycles / increased blowdown → boiler vessel link. (d) Elevated CO₂ / low condensate pH → steam-condensate link. Also: increased makeup volume, increased fuel cost, increased chemical consumption.
