Condensate handling

Ensure 100% condensate return

• look around your plant

Condensate return to boiler’s hot well

• energy efficiency
• low salts content
  • reduced pretreatment costs
  • reduced blowdown requirement
    • consider blowdown automation by conductivity measurement

Size pipework according to start up (warm up) load

• perhaps three times higher than normal operation

Flash steam from condensate

• is there a low pressure load to recover heat to?
  • perhaps through a heat exchanger to preheat boiler feed water
• if so consider expert help / advice in recovering the heat
• also reduces unsightly steam plumes

Small steam loads a long distance from the boiler house

• may not be viable to recover condensate
  • take into account energy, water and water treatment
• consider separate boiler / distributed steam system

Contaminated condensate? consider recovering heat with a heat exchanger

• as long as there is a use for the recovered heat
